[Purpose of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical image display device that selects and displays a region of interest only in a desired region of a medical image.

0002

[Background Art] When making a diagnosis by displaying medical images (hereinafter simply referred to as images) taken with various medical devices on a monitor such as a CRT, a region of interest is selected to make it easier to see only a specific region. It is common practice to perform image processing, for example window processing, only on a region based on image processing parameters.

[0003] This is because the contrast of CRT monitors, which are most widely used for image display, is low, so when you want to observe a patient's chest X-ray image, for example, it is difficult to observe the same lung field or mediastinum, which has different brightness and contrast. This is because it is difficult to observe under window processing conditions. For example, when processing is performed using window processing conditions that make it easy to observe lung field A, as shown in Figure 3, an image that makes it difficult to observe mediastinum B is displayed; When processed under these conditions, an image in which the lung field A is difficult to observe will be displayed. Therefore, when observing the lung fields and mediastinum, it is necessary to select regions of interest on each display image and independently set and process optimal window processing conditions.

0004

[Problems to be Solved by the Invention] However, in conventional medical image display devices, when setting the optimal window processing conditions each time a region of interest is selected, a complicated operation is required each time, making the operation time-consuming. There is a problem. That is, in order to set the optimal window processing conditions, it is necessary to operate operation buttons, a mouse, etc. each time a region of interest is selected, and find a state in which, for example, the lung field or mediastinum can be most easily observed.

The present invention has been made in response to the above-mentioned problems, and provides a medical image display device that can easily display a desired image in an easy-to-see manner by simply performing an operation to select a region of interest. The purpose is to

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a medical image display device that displays medical images photographed by an image photographing device on a monitor, in which a selected region of interest is set in advance. A first display means that displays a medical image processed based on processing parameters, or a second display means that displays only an image of a selected region of interest of a medical image processed based on preset image processing parameters.
and a region of interest selection means for selecting the region of interest by touching the displayed image.

[0008]

[Operation] When displaying an image by selecting a region of interest in a medical image that has been image-processed based on image processing parameters for each region of interest, or a medical image that has been image-processed based on image processing parameters, The operator selects the region of interest, for example by direct contact. This allows the desired image to be displayed easily and easily by simply selecting the region of interest on the displayed image, and since all the operator has to do is touch the displayed image, the operator does not have to take his or her eyes off the image. Therefore, diagnostic efficiency can be improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the medical image display device of the present invention, and 1 is a CPU (central processing unit).
2 is a memory for controlling the entire control operation, and 2 is a memory for storing image processing parameters corresponding to a region of interest such as the lung field or mediastinum. 3 is an image processor, 4 is an image memory, and 5 is a multi-display system, each of which is connected in parallel. Reference numeral 6 denotes a monitor consisting of a CRT for displaying images, 7 a touch panel disposed on the surface of the monitor 6, and 8 a keyboard. The touch panel 7 and the keyboard 8 constitute input means. Note that 9 indicates a high-speed data bus.

On the touch panel 7, while an image is being displayed on the monitor 6, the operator can touch a region of interest such as the lung field or the mediastinum with a finger 11 as shown in FIG.
A region of interest, such as the mediastinum or lung field, can be automatically selected by touching an arbitrary region. Alternatively, the operator may make contact using a touch pen or the like.

Next, the operation of this embodiment will be explained.

The operator first selects the patient I from the keyboard 8.
Enter D. As a result, the MDS 5 interrupts the CPU 1, and the input patient ID is read into the CPU 1. Based on this, the address and size of the image corresponding to the patient ID is searched from the table in MEM2, and this image is transferred from IM4 to MDS5 via high-speed data bus 9.
MA (Direct Memory Access) transfer is performed. At this time, the CPU 1 reads the region code of the transferred image from the MEM 2. As a result, the image to be processed is displayed on the monitor 6.

With the image displayed on the monitor 6, the operator directly touches, for example, a region of interest, such as the lung field or the mediastinum, with the finger 11 on the touch panel 7 as shown in FIG. As a result, data on the coordinates (X, Y) of the tentacled position is input to the MDS 5, and the CPU 1 reads the coordinate data via the MDS 5. Next, the CPU
1 refers to a pre-stored coordinate-image processing parameter correspondence table corresponding to the retained part code, learns, for example, gamma table type A as an image processing parameter corresponding to the input coordinate data, and selects it from MEM2. and set the IP3 gamma table parameter register to that gamma table type A.

Next, the CPU 1 transfers the image data to be processed from the IM4 to the IP3, processes the image data based on the image processing parameters, and then returns the processed image data from the IP3 to the IM4. Next, the CPU 1 transfers this image data to the MDS 5, and the MDS 5 transfers the image data to the monitor 6. As a result, the image of the region of interest specified by the finger 11 is displayed on the monitor 6 after being subjected to desired image processing.

As described above, according to this embodiment, when displaying a medical image that has been image-processed based on image processing parameters for each region of interest, all that is required is to select the region of interest on the displayed image on the monitor. A desired image can be easily displayed in an easy-to-see manner, and all that is required is for the operator to touch the displayed image, for example, by touching the displayed image. Therefore, the operator does not have to take his/her line of sight off the image each time and can continue observing the image, thereby improving diagnostic efficiency.

Next, another embodiment of the present invention will be described.

In the configuration of FIG. 1, the processed and unprocessed images of the selected region of interest are stored in the IM 4, and the monitor 6 and the image of the processed region of interest are stored in the MDS 5. Information will be inputted, and other parts will have the same functions as in FIG.

First, the CPU 1 checks the unprocessed image of the region of interest in the IM 4. Further, the CPU 1 selects an image processing parameter in the MEM 2 corresponding to the unprocessed image of the region of interest, and writes this image processing parameter to the parameter register of the IP 3. Next, the unprocessed image in IM4 is
The unprocessed image is transferred to P3, and after image processing is performed using image processing parameters, it is returned to IM4 and stored there. At this time, the leading edge address and data length of the processed image stored in IM4 are transmitted to CPU1, and MEM2
is memorized.

Next, with the image displayed on the monitor 6 as shown in FIG. 2, the operator points out a region of interest with his finger 11, and the coordinate data of this tentacle position is input into the MDS 5. This coordinate data is read into the CPU 1, and based on this input data, the tip address and data length of the processed image of the desired region of interest are determined from the MEM 2. Based on the leading address and data length obtained in this manner, the processed image of the region of interest in the IM 4 is transferred to the MDS 5 and displayed on the monitor 6 as in the previous embodiment.

As described above, in this embodiment, even when displaying an image by selecting a region of interest in a medical image that has already been image-processed based on image processing parameters, the same operations as in the previous embodiment can be performed. A similar effect can be obtained.

[0022] In this text, an example is shown in which a region of interest is selected when observing the mediastinum and lung field, but the target region can be set arbitrarily.

[0023]

As described above, according to the present invention, when selecting a region of interest on a displayed image, the operator touches the desired position to observe.
The region of interest can be selected with a simple operation that does not require any effort, and diagnostic efficiency can be improved.
