Description

Embodiments of the present invention relate to a medical image diagnostic apparatus and a medical image processing apparatus.

Since the ultrasonic wave transmitted from the ultrasonic probe travels while being attenuated in the body, the reflected signal returned from a deep part in the body is more likely to be attenuated. Therefore, the ultrasonic diagnostic apparatus has a function of presetting a gain according to the depth direction in order to make the image quality uniform. However, in reality, the degree of attenuation varies from one examination to another because of differences between organs and individuals. Therefore, the ultrasonic diagnostic apparatus has a function called STC (Sensitivity Time Control) or TGC (Time Gain Control) for adjusting the gain in the time direction, that is, the depth direction.

Further, depending on how the ultrasonic probe is applied and the condition inside the subject, the image quality may differ in the azimuth direction, for example, the left side of the ultrasonic image becomes dark. Therefore, the ultrasonic diagnostic apparatus is provided with a function called an LGC (Lateral Gain Control) that adjusts a gain in the azimuth direction.

(First embodiment)
FIG. 1 is a block diagram showing a configuration example of an ultrasonic diagnostic apparatus 1 according to the first embodiment. As shown in FIG. 1, the ultrasonic diagnostic apparatus 1 according to the first embodiment includes an apparatus body 100, an ultrasonic probe 101, an input device 102, a display 103, and a touch panel 104. The ultrasonic probe 101, the input device 102, the display 103, and the touch panel 104 are each connected to the device body 100.

The ultrasonic probe 101 is brought into contact with the body surface of the subject P and transmits/receives ultrasonic waves (ultrasonic scanning). For example, the ultrasonic probe 101 is a 1D array probe (probe) having a plurality of piezoelectric vibrators arranged one-dimensionally in a predetermined direction. The plurality of piezoelectric vibrators generate ultrasonic waves based on a drive signal supplied from a transmission circuit 110 included in the device body 100 described later. The generated ultrasonic waves are reflected by the acoustic impedance mismatching surface in the subject, and are received by the plurality of piezoelectric vibrators as reflected wave signals including components scattered by the scatterers in the tissue. The ultrasonic probe 101 sends the reflected wave signal received by the plurality of piezoelectric vibrators to the receiving circuit 120.

In the present embodiment, a case where a 1D array probe is used as the ultrasonic probe 101 will be described, but the present invention is not limited to this. For example, as the ultrasonic probe 101, a 2D array probe in which a plurality of piezoelectric vibrators are two-dimensionally arranged in a lattice pattern or a plurality of one-dimensionally arranged piezoelectric vibrators mechanically swings to 3 Any form of ultrasonic probe may be used, such as a mechanical 4D probe that scans a dimensional region.

The input device 102 has a mouse, a keyboard, buttons, a panel switch, a touch command screen, a foot switch, a trackball, a joystick, etc., and accepts various setting requests from the operator of the ultrasonic diagnostic apparatus 1 and causes the apparatus body 100 to receive the various setting requests. Transfers the various setting requests accepted.

The display 103 displays a GUI (Graphical User Interface) for the operator of the ultrasonic diagnostic apparatus 1 to input various setting requests using the input device 102, ultrasonic image data generated in the apparatus main body 100, and the like. Or display.

The touch panel 104 is a device that displays a medical image and detects a touch operation on the displayed medical image. For example, the touch panel 104 receives a touch operation including an operation such as a tap operation, a long press operation, and a slide operation. In other words, the touch panel 104 is a device that displays a medical image and detects a tap operation or a long-press operation on the displayed medical image. Specifically, the touch panel 104 detects, as the content of the touch operation, information such as a position (coordinates) touched by the operator by the touch operation, a time of touching the position, and the number of touches, and the detected information. Is output to the apparatus main body 100. The touch operation may be performed using a tool such as a stylus, for example, without the operator directly touching it.

The apparatus body 100 is an apparatus that generates ultrasonic image data based on the reflected wave signal received by the ultrasonic probe 101. As shown in FIG. 1, the device main body 100 includes, for example, a transmission circuit 110, a reception circuit 120, a signal processing circuit 130, an image processing circuit 140, an image memory 150, a storage circuit 160, and a control circuit 170. Have. The transmission circuit 110, the signal processing circuit 130, the image processing circuit 140, the image memory 150, the storage circuit 160, and the control circuit 170 are communicably connected to each other.

The transmission circuit 110 controls the transmission of ultrasonic waves by the ultrasonic probe 101. For example, the transmission circuit 110 has a trigger generation circuit, a transmission delay circuit, a pulser circuit, and the like, and supplies a drive signal to the ultrasonic probe 101. The pulsar circuit repeatedly generates rate pulses for forming transmission ultrasonic waves at a predetermined rate frequency. In addition, the transmission delay circuit determines the delay time for each piezoelectric vibrator required to focus the ultrasonic waves generated from the ultrasonic probe 101 into a beam shape and determine the transmission directivity, at each rate generated by the pulsar circuit. Give to the pulse. In addition, the trigger generation circuit applies a drive signal (drive pulse) to the ultrasonic probe 101 at a timing based on the rate pulse. That is, the transmission delay circuit arbitrarily adjusts the transmission direction from the surface of the piezoelectric vibrator by changing the delay time given to each rate pulse.

The reception circuit 120 controls reception of a reflected wave signal in which transmitted ultrasonic waves are reflected by internal tissues. For example, the reception circuit 120 has an amplifier circuit, an A/D converter, an adder, a phase detection circuit, etc., and performs various processes on the reflected wave signal received by the ultrasonic probe 101 to generate reflected wave data. To do. The amplifier circuit amplifies the reflected wave signal for each channel and performs gain correction processing. The A/D converter A/D-converts the gain-corrected reflected wave signal and gives digital data a delay time necessary for determining the reception directivity. The adder adds the reflected wave signals processed by the A/D converter. By the addition processing of the adder, the reflection component from the direction corresponding to the reception directivity of the reflected wave signal is emphasized. The phase detection circuit converts the output signal of the adder into a baseband band in-phase signal (I signal, I: In-phase) and a quadrature signal (Q signal, Q: Quadrature-phase). Then, the phase detection circuit outputs the I signal and the Q signal (IQ signal) to the subsequent signal processing circuit 130. The data before being processed by the phase detection circuit is also called an RF signal. Below, "IQ signal, RF signal" generated based on the reflected wave of the ultrasonic waves will be collectively referred to as "reflected wave data".

The signal processing circuit 130 performs various kinds of signal processing on the reflected wave data generated from the reflected wave signal by the receiving circuit 120. For example, the signal processing circuit 130 receives the reflected wave data from the receiving circuit 120, performs logarithmic amplification, envelope detection processing, and the like to generate data (B-mode data) in which the signal strength is represented by brightness of brightness. To do. In addition, the signal processing circuit 130 frequency-analyzes velocity information from the reflected wave data received from the receiving circuit 120, extracts blood flow, tissue, and contrast agent echo component due to Doppler effect, and moves average velocity, dispersion, power, and the like. Data (Doppler data) extracted from multiple points of body information is generated.

Here, the signal processing circuit 130 can process both two-dimensional reflected wave data and three-dimensional reflected wave data. That is, the signal processing circuit 130 generates two-dimensional B-mode data from the two-dimensional reflected wave data and three-dimensional B-mode data from the three-dimensional reflected wave data. The signal processing circuit 130 also generates two-dimensional Doppler data from the two-dimensional reflected wave data and three-dimensional Doppler data from the three-dimensional reflected wave data.

The image processing circuit 140 generates ultrasonic image data from the data generated by the signal processing circuit 130, and performs various kinds of image processing on the generated ultrasonic image data. That is, the image processing circuit 140 generates B-mode image data in which the intensity of the reflected wave is represented by brightness from the B-mode data. The image processing circuit 140 also generates Doppler image data as an average velocity image, a dispersed image, a power image, or a combination image thereof, which represents moving body information, from the Doppler data. The image processing circuit 140 can also generate a composite image in which the ultrasonic image is combined with character information of various parameters, scales, body marks, and the like. The image processing circuit 140 is an example of an image generation unit that generates a medical image based on the data collected by scanning the subject.

The image processing circuit 140 also converts (scan-converts) the scanning line signal sequence of ultrasonic scanning into a scanning line signal sequence of a video format typified by a television or the like, and generates ultrasonic image data as a display image. To do. Further, the image processing circuit 140 performs various image processing other than scan conversion, for example, image processing (smoothing processing) for regenerating an average brightness image using a plurality of image frames after scan conversion, Image processing (edge enhancement processing) using a differential filter is performed in the image.

That is, the B-mode data and the Doppler data are ultrasonic image data before the scan conversion process, and the data generated by the image processing circuit 140 is the ultrasonic image data for display after the scan conversion process.

Further, the image processing circuit 140 performs a rendering process on the volume data in order to generate various two-dimensional image data for displaying the volume data on the display 103 or the touch panel 104. As the rendering process performed by the image processing circuit 140, there is a process of performing a cross-sectional reconstruction method (MPR: Multi Planar Reconstruction) to generate MPR image data from volume data. The rendering process performed by the image processing circuit 140 includes a process of performing “Curved MPR” on the volume data and a process of performing “Intensity Projection” on the volume data. Further, as the rendering process performed by the image processing circuit 140, there is a volume rendering (VR) process for generating two-dimensional image data that reflects three-dimensional information.

The image memory 150 is a memory that stores the image data generated by the image processing circuit 140. Further, the image memory 150 can also store the data generated by the signal processing circuit 130. The data stored in the image memory 150 can be called by an operator after the diagnosis, for example, and becomes ultrasonic image data for display via the image processing circuit 140.

The memory circuit 160 stores a control program for performing ultrasonic wave transmission/reception, image processing, and display processing, diagnostic information (for example, patient ID, doctor's findings, etc.), and various data such as a diagnostic protocol and various body marks. .. The storage circuit 160 is also used for storing image data stored in the image memory 150, etc., as needed. In addition, the data stored in the storage circuit 160 can be transferred to an external device via an interface unit (not shown).

The control circuit 170 controls the entire processing of the ultrasonic diagnostic apparatus 1. Specifically, the control circuit 170 receives signals from the transmission circuit 110 based on various setting requests input by the operator via the input device 102 or the touch panel 104, various control programs and various data read from the storage circuit 160, and the receiving circuit. The processing of the circuit 120, the signal processing circuit 130, the image processing circuit 140, and the like is controlled. Further, the control circuit 170 causes the display 103 to display the ultrasonic image data stored in the image memory 150.

The image processing circuit 140 and the control circuit 170 according to the first embodiment execute each processing function described in this embodiment. Here, each processing function executed by the image processing circuit 140 and the control circuit 170 is recorded in the storage circuit 160 in the form of a program executable by a computer, for example. The image processing circuit 140 and the control circuit 170 are processors that realize the functions corresponding to the programs by reading the programs from the storage circuit 160 and executing them. In other words, the image processing circuit 140 and the control circuit 170 in a state where each program is read out have each processing function. The processing functions of the image processing circuit 140 and the control circuit 170 will be described later.

It should be noted that the image processing circuit 140 and the control circuit 170 may be configured so that a plurality of independent processors are combined to form a processing circuit, and each processor executes a program to realize the function.

The word "processor" used in the above description is, for example, a CPU (Central Preprocess Unit), a GPU (Graphics Processing Unit), an application specific integrated circuit (ASIC), a programmable logic device (for example, It means a circuit such as a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA). The processor realizes the function by reading and executing the program stored in the memory circuit. Instead of storing the program in the memory circuit 160, the program may be directly incorporated in the circuit of the processor. In this case, the processor realizes the function by reading and executing the program incorporated in the circuit. It should be noted that each processor of the present embodiment is not limited to the case where each processor is configured as a single circuit, and a plurality of independent circuits may be combined to configure one processor to realize its function. Good. Further, the plurality of constituent elements in FIG. 1 may be integrated into one processor to realize its function.

Here, TGC (Time Gain Control) that adjusts the gain in the depth direction and LGC (Lateral Gain Control) that adjusts the gain in the azimuth direction will be described.

2 and 3 are diagrams for explaining the TGC and the LGC. FIG. 2 illustrates the positions where the TGC and the LGC are installed in the ultrasonic diagnostic apparatus 1. Further, FIG. 3 exemplifies gain adjustment by TGC and LGC. As shown in FIG. 2, the TGC and the LGC are arranged on the operation panel 10 of the ultrasonic diagnostic apparatus 1.

As shown in FIG. 3, each of the TGC and the LGC has a plurality of knobs, and by individually moving them, the brightness of the ultrasonic image is partially changed. For example, the TGC has eight knobs in the vertical direction. Each of the eight knobs corresponds to each region obtained by dividing the ultrasonic image into eight equal parts in the depth direction. Further, the LGC has six knobs in the lateral direction. Each of the six knobs corresponds to each region obtained by dividing the ultrasonic image into six equal parts in the azimuth direction.

In FIG. 3, a case where the area 11 of the ultrasonic image is brightened will be described. In this case, the operator moves the fourth knob 12 from the top of the TGC to the right, moves the second knob 15 from the left of the LGC to the top, or performs both operations. These operations make the area 11 brighter, but the operations also affect areas other than the area 11. Specifically, by moving the knob 12 to the right, the regions 13 and 14 in the same depth direction as the region 11 also become bright. Further, by moving the knob 15 upward, the regions 16 and 17 in the same azimuth direction as the region 11 also become bright.

As described above, in the operations of TGC and LGC, when the operator adjusts the brightness of the desired area, the areas other than the desired area are also affected. Therefore, for example, if the brightness of an area that was originally appropriate brightness changes, the diagnosis may be affected. That is, the brightness of a desired area may not always be changed by the operation of TGC and LGC. In the above description, the brightness of the image has been described, but the present invention is not limited to this, and is widely common when changing the parameters that affect the display of the image, such as the image processing filter, frequency, and dynamic range.

Therefore, the ultrasonic diagnostic apparatus 1 according to the present embodiment has the disclosed configuration in order to easily change the image quality of a desired region.

The touch panel 104 displays a medical image and detects a touch operation on the displayed medical image. For example, the touch panel 104 is installed on the operation panel 10 of the ultrasonic diagnostic apparatus 1 and displays the ultrasonic image generated by the image processing circuit 140. Then, the touch panel 104 receives the designation of the position (coordinates) on the displayed ultrasonic image by the touch operation (touch on the screen) by the operator. The touch panel 104 does not necessarily have to be installed on the operation panel. For example, the touch panel 104 may be installed next to the display 103 as a sub-display, or may be installed as a main display that also serves as the display 103. The touch panel 104 may be provided in a separate housing as an external device of the ultrasonic diagnostic apparatus 1.

FIG. 4 is a diagram for explaining the process of the touch panel 104 according to the first embodiment. FIG. 4 illustrates the touch panel 104 that displays an ultrasonic image. As shown in FIG. 4, the touch panel 104 detects a touch operation by the operator. Specifically, when the operator taps one point on the touch panel 104, the touch panel 104 detects the coordinates (X, Y) of the tapped position. Then, the touch panel 104 outputs the detected coordinates (X, Y) to the control circuit 170.

Note that FIG. 4 is merely an example, and the touch panel 104 may receive a touch operation other than a tap, for example. For example, the touch panel 104 accepts operations such as long pressing and sliding as touch operations other than taps. Here, when the long press is accepted, the touch panel 104 outputs the position (coordinates) designated by the operator and the time during which the position is long pressed. When the slide is accepted, the touch panel 104 outputs the coordinates of a plurality of positions traced by the slide. Further, for example, when the touch panel 104 receives a plurality of taps, the number of taps can be output.

The control circuit 170 changes the parameter that affects the display of the medical image in the area based on the position where the tap operation or the long press operation is detected. For example, the control circuit 170 sets the parameter that affects the display of the medical image in the area based on the position where the tap operation or the long press operation is detected, according to the number of tap operations or the long press time of the long press operation. To change.

For example, the control circuit 170 changes the parameter in the area including the position where the touch operation is detected. Specifically, the control circuit 170 changes the parameter in a square area, a cubic area, a circle area, or a sphere area including the position where the tap operation or the long press operation is detected.

5A to 5D are diagrams for explaining the processing of the control circuit 170 according to the first embodiment. FIG. 5A illustrates a plurality of scan lines in Raw data (before scan conversion). Further, FIG. 5B and FIG. 5C exemplify the amount of change in gain according to the distance from the reference (reference point). 5B and 5C, the horizontal axis represents the position (azimuth direction, depth direction), and the vertical axis represents the amount of change. Further, FIG. 5D illustrates a plurality of scan lines on the ultrasonic image (after scan conversion). 5A to 5D, the case where the touch panel 104 taps the position of the coordinates (X, Y) once will be described.

As shown in FIG. 5A, when the control circuit 170 receives the coordinates (X, Y) output by the touch panel 104, the control circuit 170 calculates the coordinates (Xr, Yr) on the Raw data corresponding to the coordinates (X, Y). To do. Then, the control circuit 170 determines the rectangular area 20 having the calculated coordinates (Xr, Yr) as the center (reference point) as the area for changing the parameter. Here, as an example, the control circuit 170 determines the rectangular area 20 centered on the coordinates (Xr, Yr) and included in x in the left-right direction and y in the up-down direction as an area for changing the parameter. The size of the rectangular area 20 is preset by the operator and is registered in the memory circuit 160, for example.

As shown in FIGS. 5B and 5C, the control circuit 170 determines the amount of change in the parameter according to the distance from the reference (reference point). For example, the control circuit 170 determines the change amount in the azimuth direction such that the change amount of the gain decreases as the distance from the reference point (Xr) increases. Similarly, the control circuit 170 also determines the variation amount in the depth direction such that the variation amount of the gain decreases as the distance from the reference point (Yr) increases. The amount of change in gain is preset by the operator and registered in the memory circuit 160, for example.

Then, the control circuit 170 changes the gain corresponding to each sample point included in the determined rectangular area 20 according to the determined change amount. For example, the control circuit 170 changes the gain of the gain correction process performed by the reception circuit 120 for each sample point according to the determined change amount. Specifically, the control circuit 170 changes the gain of each sample point registered in the reception circuit 120 according to the determined change amount.

After that, the gain of the rectangular area 20 centered on the coordinates (X, Y) is changed in the generated ultrasonic image. The shape of the rectangular area 20 in the ultrasonic image is distorted due to scan conversion (see FIG. 5D). In this shape, the sample points whose depth direction coincides with each other are parameters to be changed, and therefore it can be said that the shape is suitable for the characteristics of ultrasonic diagnostic imaging in which the reflected signal is likely to be attenuated in the depth direction.

In this way, the control circuit 170 changes the parameter in the area based on the position of the touch operation. Note that FIGS. 5A to 5D are merely examples. For example, the shape of the area whose parameters are to be changed is not limited to a rectangle (for example, a square area), and any shape such as a circle (for example, a circular area) or an ellipse can be set. Although the shape of the region to be changed is set on the raw data before scan conversion here, the shape is not limited to this, and may be set on the ultrasonic image after scan conversion, for example. Since the reflected signal is likely to be attenuated in the depth direction in the ultrasonic image diagnosis, it is preferable that the shape is set according to the shape of the contact point of the ultrasonic probe 101 with the subject, for example. Further, the amount of change in the parameter according to the distance from the reference is not limited to the curve (S-shaped change) as shown in FIGS. 5B and 5C, and may be linear, or a constant amount of change regardless of the distance. It may be.

Further, in the above example, the case where the parameter related to Raw data is changed has been described, but the present invention is not limited to this. For example, the parameters relating to the IQ signal (IQ data) may be changed. In this case, parameters such as the reception frequency can be adjusted. In other words, since it is possible to locally set the high-frequency image quality, it is suitable for viewing only the tumor part in the image with high image quality. Alternatively, the parameters of the ultrasonic image after scan conversion may be changed.

In the above example, the case where the touch panel 104 receives one tap is described, but the embodiment is not limited to this. For example, when taps are received multiple times, the control circuit 170 may change the parameter according to the number of taps. In addition, if it is a long press, the control circuit 170 may change the parameter according to the time of the long press. According to this, for example, the longer the operator is tapping, the brighter the brightness of the image in the area with the contact point as the reference point. In this case, the degree of increase of the gain with respect to the contact time may be set by the user. Further, conversely, it may be set so that it can be darkened according to the contact time.

FIG. 6 is a flowchart showing a processing procedure of the ultrasonic diagnostic apparatus 1 according to the first embodiment. The processing procedure shown in FIG. 6 is started, for example, by receiving an instruction from the operator to start B-mode imaging when the ultrasonic probe 101 is in contact with the body surface of the subject P.

In step S101, the ultrasonic diagnostic apparatus 1 determines whether to start B-mode imaging. For example, when the control circuit 170 receives an instruction to start B-mode shooting from the operator, the control circuit 170 starts B-mode shooting. If step S101 is denied, the control circuit 170 does not start shooting and is in a standby state.

When step S101 is affirmed, in step S102, the ultrasonic diagnostic apparatus 1 generates a B-mode image and displays it on the touch panel 104.

In step S103, the touch panel 104 determines whether a touch operation has been detected. For example, when the touch panel 104 detects a touch operation, the touch panel 104 outputs the coordinates designated by the detected touch operation to the control circuit 170. In addition, when step S103 is denied, the control circuit 170 transfers to the process of step S105.

When step S103 is positive, the control circuit 170 changes the parameter in the area based on the position of the touch operation in step S104. For example, the control circuit 170 determines the rectangular area 20 centered on the tapped position as the area for changing the parameter. Then, the control circuit 170 determines the amount of change in the parameter according to the distance from the reference (reference point). Then, the control circuit 170 changes the gain corresponding to each sample point included in the determined rectangular area 20 according to the determined change amount.

In step S105, the control circuit 170 determines whether or not an instruction to end the B-mode shooting has been received from the operator. Here, when step S105 is denied, the control circuit 170 moves to the processing of step S102. That is, the ultrasonic diagnostic apparatus 1 performs ultrasonic scanning of the next frame to generate and display the B-mode image of the next frame.

If step S105 is affirmed, the ultrasonic diagnostic apparatus 1 ends the process of B-mode imaging. Note that FIG. 6 is merely an example. For example, the processing procedure described above does not necessarily have to be executed in the order described above. For example, the above steps S101 to S105 may be executed by appropriately changing the order as long as the processing content does not conflict.

As described above, in the ultrasonic diagnostic apparatus 1 according to the first embodiment, the touch panel 104 displays a medical image and detects a touch operation on the displayed medical image. The control circuit 170 changes the parameter that affects the display of the medical image in the area based on the position where the touch operation is detected. According to this, the ultrasonic diagnostic apparatus 1 can easily change the image quality of a desired area.

(Modification of the first embodiment)
In the first embodiment, the case where the parameter is changed according to the preset value, that is, the case where the parameter is increased or decreased has been described, but the embodiment is not limited to this. For example, the ultrasonic diagnostic apparatus 1 may change the parameter by the touch operation after the operator selects the increase/decrease of the parameter.

FIG. 7 is a diagram for explaining processing of the touch panel 104 and the control circuit 170 according to the modified example of the first embodiment. The touch panel 104 illustrated in FIG. 7 displays a GUI 30 for selecting increase/decrease of parameters on the ultrasonic image. The GUI 30 illustrated in FIG. 7 is currently displaying “Down”. The display of "Down" indicates that when the touch panel 104 receives a touch operation in this situation, the predetermined parameter decreases.

As shown in FIG. 7, the touch panel 104 displays the GUI 30. Here, when the operator taps the GUI 30, “Down” is switched to “Up”. The display of “Up” indicates that when the touch panel 104 receives a touch operation in this situation, the predetermined parameter increases.

That is, the touch panel 104 displays a graphic for determining whether to increase or decrease the parameter, and detects a touch operation on the displayed graphic. Then, the control circuit 170 changes the setting of whether to increase or decrease the parameter by the touch operation on the medical image according to the touch operation detected on the graphic. According to this, the operator can change the parameter by the touch operation after selecting whether to raise or lower the parameter.

The GUI displayed on the touch panel 104 is not limited to the GUI 30 described above. For example, the touch panel 104 may display a “Undo” button for returning the operation content for one time. This is useful when the operator wants to invalidate the immediately preceding operation when the gain is increased too much.

The touch panel 104 may also display a “Reset” button for returning the parameter change history to the initial state. This is useful when changing the field of view (operation range). For example, if the user browses the tomographic image of the liver in a state where the gain of a part of the ultrasound image is increased and then switches to the browsing of the kidney, the change history of the parameters changed in the browsing of the liver should be unnecessary. .. In this case, by pressing the “Reset” button once, the change of the parameter set in the liver is returned to the initial setting, and the tomographic image of the kidney can be drawn in the initial setting.

(Second embodiment)
In the first embodiment, the case where the parameter is changed in the area including the position where the touch operation is detected has been described, but the embodiment is not limited to this. For example, the ultrasonic diagnostic apparatus 1 may change the parameters of the area surrounded by the plurality of positions designated by the touch operation.

The ultrasonic diagnostic apparatus 1 according to the second embodiment has the same configuration as the ultrasonic diagnostic apparatus 1 illustrated in FIG. 1 and a part of the processing of the control unit 170 is different. Therefore, in the second embodiment, the points different from the first embodiment will be mainly described, and the description of the points having the same function as the configuration described in the first embodiment will be omitted.

FIG. 8 is a diagram for explaining the processing of the control circuit 170 according to the second embodiment. The arrow in FIG. 8 represents the locus of the touch operation traced by the operator on the touch panel 104.

As shown in FIG. 8, when the operator performs a circular touch operation on the touch panel 104, the touch panel 104 sequentially detects the coordinates of a plurality of positions on the traced trajectory. Then, the touch panel 104 outputs the detected plurality of coordinates to the control circuit 170.

Then, when the touch panel 104 detects a touch operation that specifies a plurality of positions, the control circuit 170 changes the parameter in the area surrounded by the detected plurality of positions. Specifically, the control circuit 170 changes the parameter in the area surrounded by the arrow in FIG. According to this, the operator can change the parameters for a region having an arbitrary shape.

(Third Embodiment)
In the above embodiment, the case where the parameter is changed in the two-dimensional ultrasonic image data has been described, but the embodiment is not limited to this. For example, the ultrasonic diagnostic apparatus 1 may change parameters for three-dimensional ultrasonic image data.

9A and 9B are views for explaining the processing of the touch panel 104 and the control circuit 170 according to the third embodiment. In FIG. 9A and FIG. 9B, the lower right image is an image obtained by VR-processing the volume data in which the appearance of the fetus is depicted. The upper right, upper left, and lower left images are cross-sectional images in the x, y, and z directions of the volume data.

As shown in FIG. 9A, for example, the touch panel 104 detects the coordinates (X, Y, Z) in the volume data by tapping the cross-sectional image. Then, the touch panel 104 outputs the detected coordinates (X, Y, Z) to the control circuit 170.

Then, the control circuit 170 changes a predetermined parameter by a predetermined amount in a region based on the coordinates (X, Y, Z) output by the touch panel 104. As a result, as shown in FIG. 9B, an image in which the parameters of the areas 40, 41, 42 are changed is displayed. If the changed area is not included in the cross section, an image that does not include the area in which the parameter is changed is displayed as shown in the upper right of FIG. 9B. As described above, the change of the parameter by the touch operation can be applied to the three-dimensional ultrasonic image data.

Further, even on the VR image (the image at the lower right of FIG. 9A), it is possible to apply the parameter change by the touch operation by setting a predetermined algorithm. For example, when a point (position) on the three-dimensional surface is designated by tapping, the position can be designated also on the VR image. Therefore, the parameter change by the touch operation can be applied by the processing described above. Further, here, the case where the parameter is changed for the spherical region has been described, but the present invention is not limited to this, and the parameter may be changed for the cubic region, for example.

(Other embodiments)
Other than the above-described embodiment, various other forms may be implemented.

(Combination of touch operation)
For example, although cases have been described with the above embodiments where various touch operations such as a tap operation, a long-press operation, and a slide operation are individually performed, these operations may be appropriately combined and implemented. For example, the operator may increase the gain according to the time of the long press operation, and then perform a tap operation to perform fine adjustment of the gain, and change the gain according to the number of tap operations. Further, the parameter to be changed may be different for each touch operation. For example, the operator may change the gain according to the time of the long press operation and change the dynamic range according to the number of tap operations.

(When the medical image is not displayed on the touch panel)
For example, the present embodiment can be applied to a touch panel without displaying a medical image.

FIG. 10: is a figure which shows the structural example of the ultrasonic diagnosing device 1 which concerns on other embodiment. As shown in FIG. 10, the touch panel 50 is provided in a housing different from the display 103 of the ultrasonic diagnostic apparatus 1, has an area whose positional relationship corresponds to the medical image displayed on the display 103, and The touch operation from the operator is detected. For example, the touch panel 50 does not display a medical image, but its position on the screen is associated with the position of the medical image on the display 103. Then, the touch panel 50 detects a touch operation performed by the operator. By this operation, the touch panel 50 can detect the touch operation on the medical image.

Then, the control circuit 170 changes the parameter that affects the display of the medical image in the area based on the position in the medical image corresponding to the position where the touch operation is detected. For example, the control circuit 170 changes the parameter based on the position on the display 103 corresponding to the position detected on the touch panel 50.

(Other position input means)
In addition, the ultrasonic diagnostic apparatus 1 can change the parameters by other position input means. That is, in the ultrasonic diagnostic apparatus 1, the input device 102 receives a non-contact operation for designating a position in the medical image. Then, the control circuit 170 changes at least the parameter that affects the display of the medical image at the position designated by the non-contact operation.

FIG. 11 is a diagram for explaining a position input means according to another embodiment. FIG. 11 illustrates position input by an operator who wears an HMD (Head Mounted Display) as the input device 102. As shown in FIG. 11, the operator wearing an HMD (Head Mounted Display) designates the position (coordinates) by looking at one point on the medical image. When the position is detected, the control circuit 170 can change the parameter in the region based on the position, as in the above-described embodiment.

Further, as the input device 102, an input unit by pseudo contact with a medical image projected in space may be applied. This is a means for drawing an image at a position where nothing should exist by forming an image in space by a technique called spatial display, spatial projection, or the like. Then, by specifying the position for this image with a plurality of infrared sensors, for example, position input becomes possible. For example, the operator designates the position with a fingertip on the spatially projected medical image. The position designated individually is detected by a plurality of infrared sensors. Then, the position detected by the infrared sensor is coordinate-converted based on the positional relationship with the position of the image spatially projected, whereby the position can be detected as the position designation for the medical image.

A voice input unit may be applied as the input device 102. In this case, the keyword capable of voice detection and the position (area) on the medical image are associated and registered in advance. For example, the medical image is divided into four and associated with keywords such as upper right, lower right, upper left, and lower left. Thus, for example, when the operator says "upper right", this keyword is detected by the voice input means and converted into a medical image area. In this case, the parameters in the upper right area of the medical image are changed.

(Other shooting modes)
Further, in the above embodiment, the case where the parameter is set in the B mode shooting has been described, but the embodiment is not limited to this. For example, it is also applicable to B mode, M mode, Doppler mode, color Doppler mode, power mode, tissue Doppler mode, and elast mode.

In this case, when the medical image is generated in the B mode, the control circuit 170 changes any one of the gain, the dynamic range, the noise reduction filter level, and the reception frequency as a parameter, and the medical image is changed in the M mode. If it is generated, any one of M gain, M dynamic range, noise reduction filter level, edge enhancement level, and reception frequency is changed as a parameter, and if a medical image is generated in the Doppler mode, the Doppler gain is generated. , Doppler dynamic range, noise reduction filter level, and received frequency are changed as parameters, and when a medical image is generated in color Doppler mode, color gain, motion artifact reduction filter level, low cut filter level, And change any one of the reception frequency as a parameter, when a medical image is generated in the power mode, change any one of the color gain, power dynamic range, low cut filter level, and the reception frequency as a parameter, When a medical image is generated in tissue Doppler mode, one of color gain, motion artifact reduction filter level, and reception frequency is changed as a parameter, and when a medical image is generated in elast mode, Any one of the stance level, the reception frequency, and the mixing ratio between the elast image and the image to be mixed is changed as a parameter. In the elast mode, a color image (hardness image) is displayed in a semi-transparent manner on a 2D image. Increase the transparency of. According to this, it becomes possible to improve the visibility of the 2D image of the lower layer of the color image.

(Flick operation)
Further, although cases have been described with the above embodiments where tap operations, long-press operations, and the like are performed as examples of touch operations, the embodiments are not limited to this. For example, a flick operation may be performed as a touch operation. The flick operation is, for example, an operation in which the operator quickly slides his/her finger on the screen of the touch panel 104. In this case, the touch panel 104 can acquire information such as a position where a flick operation is detected (a position where a finger touches first is preferable), a direction of the flick operation, a speed of the flick operation, and the like. The flick operation may be defined as, for example, a quick operation that is equal to or faster than a predetermined speed, or may be defined separately from an operation (slide operation) that is less than the speed. Alternatively, the flick operation and the slide operation may be defined as the same operation.

That is, the touch panel 104 displays a medical image and detects a flick operation on the displayed medical image. Then, the control unit 170 sets a parameter that affects the display of the medical image in at least one of the direction of the flick operation and the speed of the flick operation in the area based on the position where the flick operation is detected. change.

FIG. 12 is a diagram for explaining processing of the touch panel according to another embodiment. FIG. 4 illustrates the touch panel 104 that displays an ultrasonic image. As shown in FIG. 4, the touch panel 104 detects a flick operation in an upward direction, a downward direction, a right direction, and a fattening direction at coordinates (X, Y) on the ultrasonic image. In FIG. 12, the control unit 170 changes a parameter within a predetermined area centered on the coordinates (X, Y).

Here, the control unit 170 determines the type of the changed parameter to be changed and whether to increase or decrease the parameter according to the direction of the flick operation detected by the touch panel 104. For example, when the touch panel 104 receives an upward flick operation, the control unit 170 determines the parameter type “gain” and the parameter “increase”. That is, when the operator performs a flick operation in the upward direction, the control unit 170 determines to increase the gain of the ultrasonic image. Further, for example, when the touch panel 104 receives a downward flick operation, the control unit 170 determines the parameter type “gain” and the parameter “fall”. That is, when the operator performs a flick operation in the downward direction, the control unit 170 determines to decrease the gain of the ultrasonic image. Further, for example, when the touch panel 104 receives a rightward flick operation, the control unit 170 determines the parameter type “dynamic range” and “increase” the parameter. That is, when the operator performs a flick operation in the right direction, the control unit 170 determines to increase the diamond range of the ultrasonic image. Further, for example, when the touch panel 104 receives a leftward flick operation, the control unit 170 determines the parameter type “dynamic range” and the parameter “fall”. That is, when the operator performs a flick operation to the left, the control unit 170 determines to lower the dynamic range of the ultrasonic image.

The control unit 170 also determines the amount of change in the parameter to be changed according to the speed of the flick operation detected by the touch panel 104. As an example, the control unit 170 determines to change (increase or decrease) the parameter largely as the speed of the flick operation increases.

In this way, the control unit 170 changes the parameter according to the direction and speed of the flick operation detected by the touch panel 104.

Note that FIG. 12 is just an example. For example, the types of parameters and the increasing/decreasing directions of parameters determined according to the direction of the flick operation are not limited to the above example. Specifically, as the parameter type, any of the above-mentioned other meters such as the edge emphasis level and the reception frequency may be changed. Also, the parameter may be reduced by an upward flick operation. Further, when the touch panel 104 detects a flick operation in an oblique direction, the type of parameter may be changed according to the direction.

(Detection of strong push)
When the touch panel 104 can detect the strength of the touch operation, the control unit 170 may change the parameter based on the strength of the touch operation.

For example, the touch panel 104 in which a capacitance type detection mechanism and a pressure sensitive type detection mechanism are combined can detect the strength of the touch operation. In this case, the touch panel 104 includes an electrostatic capacitance type detection mechanism on the outer layer side that can be touched by the operator and a pressure sensitive type detection mechanism on the inner layer side. Here, the capacitance type detection mechanism detects information such as a position (coordinates) touched by the operator by a touch operation, a time at which the operator has touched the position, and the number of times of touch. On the other hand, the pressure-sensitive detection mechanism detects a touch operation with a certain strength or more (also referred to as “strong push” or “push”). The pressure-sensitive detection mechanism includes, for example, a glass that is bent by a pressure of a certain strength or more, and detects whether or not the touch operation is a hard push by detecting the bending of the glass.

In this case, the control unit 170 determines the type of parameter and whether to increase or decrease the parameter each time a tap operation, a long-press operation, or a flick operation with a predetermined strength or more is detected.

For example, the type of the parameter and the pattern of increasing or decreasing the parameter are set in advance, and the control unit 170 switches this pattern each time a strong push is detected.

As an example, the first pattern “increases the gain”, the second pattern “decreases the gain”, the third pattern “increases the dynamic range”, and the fourth pattern “decreases the dynamic range”. It is set in advance, and the control unit 170 switches between the first pattern to the fourth pattern in order according to the number of times of strong pressing.

Specifically, the control unit 170 presets the first pattern when a strong push (tap operation) has not been received even once. In this case, when the touch panel 104 detects a tap operation, the control unit 170 increases the gain according to the position and the number of tap operations.

Here, when the touch panel 104 detects a strong push once, the control unit 170 switches from the first pattern to the second pattern. When the touch panel 104 detects a tap operation with the second pattern set, the control unit 170 lowers the gain according to the position and the number of tap operations.

Subsequently, when the touch panel 104 detects a strong push once (that is, when a total of two strong pushes are detected from the preset state), the control unit 170 switches from the second pattern to the third pattern. When the touch panel 104 detects a tap operation with the third pattern set, the control unit 170 increases the dynamic range according to the position and the number of tap operations.

Further, when the touch panel 104 detects a strong push once (that is, when a total of three strong pushes are detected from the preset state), the control unit 170 switches from the third pattern to the fourth pattern. When the touch panel 104 detects a tap operation with the fourth pattern set, the control unit 170 lowers the dynamic range according to the position and the number of tap operations.

In this way, the control unit 170 switches the type of parameter and the pattern of raising or lowering the parameter each time a strong push is detected, thereby raising or lowering the type of parameter or the parameter. Decide what to do. It should be noted that, in the above example, the strong pressing of the tap operation is described, but it is also possible to detect the strong pressing of the long pressing operation and the strong pressing of the flick operation, respectively, and adjust the parameter according to the detected operation. .. That is, the control unit 170 determines the type of parameter and whether to increase or decrease the parameter each time a tap operation, a long-press operation, or a flick operation having a predetermined strength or higher is detected.

(combination)
As described above, the various embodiments described above may be appropriately combined and implemented. That is, the touch panel 104 displays a medical image and detects a tap operation, a long press operation, or a flick operation on the displayed medical image. The control unit 170 determines the parameters that affect the display of the medical image in the area based on the position where the tap operation, the long-press operation, or the flick operation is detected as the strength of the tap operation, the number of tap operations, and the length of the tap operation. The value is changed according to at least one of the strength of the push operation, the long press time of the long press operation, the strength of the flick operation, the direction of the flick operation, and the speed of the flick operation.
