Description

  The present invention relates to a radiographic apparatus capable of acquiring a fluoroscopic image of a subject, and more particularly to a radiographic apparatus that displays a radiographic image and various radiographic conditions on a single monitor.

  A medical institution is equipped with a radiation imaging apparatus that acquires a captured image of a subject. A conventional configuration of such a radiation imaging apparatus will be described. A conventional radiation imaging apparatus includes a top plate on which a subject is placed, a radiation source provided on the top of the top, a radiation detection means (FPD) provided on the bottom of the top, and a captured radiography. A display unit (monitor) for displaying an image is provided. Such a configuration is described in Patent Document 1, for example.

  A configuration of a conventional monitor will be described. The conventional radiation imaging apparatus is provided with two monitors 51 and 52 as shown in FIG.

  However, the conventional radiographic apparatus has the following problems. In other words, the conventional radiographic apparatus has a disadvantageous configuration when aiming to reduce the size of the apparatus. In order to achieve miniaturization, it is better to adopt a system that has a single console rather than having two consoles. In connection with this, the structure which makes a monitor single is desired. By doing so, the monitors can be combined into one, so that the space necessary for occupying one monitor can be released.

  Such a change in settings may seem easy to achieve, but it is not. When a single monitor is used, the radiographic image displayed on the first monitor 51 is displayed largely at the center of the monitor, and various conditions displayed on the second monitor 52 are displayed on the end of the monitor. . Then, the various conditions displayed on the second monitor 52 must be displayed in a small line in a band-like area on the monitor, which is difficult for the operator to see.

  The surgeon at the time of examination does not move around the subject and keep sitting in front of the monitor by giving instructions to the subject or operating the radiation imaging apparatus main body. If the operator does not stare at the monitor, the operation cannot be performed, which hinders the mobility of the operator and makes the examination inefficient. Because of such a problem, even if a single console is used, there is a situation where a single monitor cannot be used.

  In addition, it seems that the above-mentioned problem will be solved if a single huge monitor is prepared. However, such a monitor occupies a limited space in the examination room. When the examination room is small, it is difficult to install a radiation imaging apparatus having a huge monitor. Thus, it is necessary to realize excellent operability even with a small monitor by devising the display method of the monitor.

  Embodiments of the radiation imaging apparatus according to the present invention will be described below. The X-ray in Example 1 is an example of the radiation of the present invention.

  First, the configuration of the X-ray imaging apparatus 1 according to the first embodiment will be described. FIG. 1 is a functional block diagram illustrating the configuration of the X-ray imaging apparatus according to the first embodiment. As shown in FIG. 1, the X-ray imaging apparatus 1 according to the first embodiment is provided with a top plate 2 on which a subject M is placed, an FPD 4 provided at a lower portion of the top plate 2, and an upper portion of the top plate 2. The X-ray tube 3 for irradiating the cone-shaped X-ray beam toward the FPD 4 and a position where the FPD 4 and the X-ray tube 3 are interposed, and provided to cover the X-ray detection surface of the FPD 4 are scattered. An X-ray grid 5 for removing X-rays and an X-ray tube control unit 6 for controlling the tube voltage of the X-ray tube 3 are provided. The X-ray tube corresponds to the radiation source of the present invention, and the FPD corresponds to the detection means of the present invention.

  The X-ray grid 5 is provided so as to cover a detection surface for detecting X-rays in the FPD 4. The X-ray grid 5 is a plate-like member in which elongated absorption foils are arranged in the vertical direction in the horizontal direction. X-rays scattered in the subject M and disturbed in the traveling direction are incident on the absorbing foil and absorbed, and do not reach the FPD 4. In this way, the influence of scattered X-rays that obstruct the acquisition of the projection image of the subject is removed, and a clearer X-ray image can be acquired.

  In addition, the X-ray imaging apparatus 1 according to the first embodiment assembles the detection signals output from the FPD 4 to generate an X-ray imaging image, and the X-ray tube control unit 6 performs X-ray irradiation. A determination unit 13 that determines whether to pass an instruction, a time storage unit 15 that stores time, and an instruction input switch 22 that is used by an operator to instruct X-ray irradiation are provided. The captured image generation unit corresponds to the captured image generation unit of the present invention, and the determination unit corresponds to the determination unit of the present invention. The time storage unit corresponds to the time storage means of the present invention, and the instruction input switch corresponds to the instruction input means of the present invention. This instruction input switch instructs the X-ray tube 3 to actually irradiate the X-ray tube 3 if it can input a prior instruction to notify the X-ray tube 3 that X-ray irradiation is executed in advance. It is also possible to input an actual instruction for performing. Therefore, the instruction input switch has the functions of the prior instruction input means and the actual instruction input means of the present invention.

  The exposure correction unit 12 corrects the pixel value of the original image output from the captured image generation unit 11 and changes the contrast and luminance of the image. The parameter storage unit 16 is a storage unit that stores the tube current, tube voltage, time width of X-ray irradiation, and the like of the X-ray tube 3. The parameter storage unit 16 stores a plurality of data sets associated with the parameters as described above.

  The X-ray imaging apparatus 1 includes a display unit 21 that displays an X-ray imaging image. The configuration of the display unit 21 will be specifically described. As shown in FIG. 2, the display unit 21 has a single screen (display) D and displays various data and parameters in the X-ray imaging apparatus 1. The diagonal dimension of the screen D is 21 inches or less, and even if the space of the examination room where the X-ray imaging apparatus 1 is installed is limited, it can be easily installed. The display unit 21 corresponds to display means of the present invention.

  Various areas are provided on the screen D of the display unit 21. First, the screen D is provided with a photographic image display region R1 for displaying a photographic image of the subject. This area is assigned the maximum area among the various areas provided on the screen D. The photographed image of the subject is captured up to the fine structure of the subject, and the photographed image display region R1 should be large if the operator wants to visually recognize this. Note that a portion of the screen D other than the photographic image display region R1 is referred to as a photographic image non-display region.

  The captured image non-display area is provided with a parameter display area R2 for displaying various parameters such as the subject ID, the X-ray captured image serial number, and the imaging date and time. In the captured image non-display area, various operation icons related to acquisition of the X-ray captured image are arranged in the icon display area R3. The parameter display area R2 and the icon display area R3 are arranged in a portion other than the photographed image display area R1, and specifically, are positioned on the L-shaped side portion of the screen D.

  Next, the instruction input switch 22 will be described. As shown in FIG. 3, the instruction input switch 22 is a hand switch provided at the end of the cord, and the surgeon can hold it during the examination. This instruction input switch 22 is a two-stage switch having two contacts. When the button 22a of the instruction input switch 22 is pressed, first, the button 22a is depressed to the first depth. At this point, one of the contacts is turned on and the other contact remains off. When further force is applied to the button 22a from this state, the button 22a is depressed to the second depth. At this time, the other contact that was in the OFF state is turned ON.

  The X-ray imaging apparatus 1 also includes a main control unit 25 that comprehensively controls the X-ray tube control unit 6, the captured image generation unit 11, the exposure correction unit 12, and the determination unit 13. The main control unit 25 is constituted by a CPU, and realizes the units 6, 11, 12, and 13 by executing various programs.

  The operation of the X-ray imaging apparatus 1 having such a configuration will be described. First, the subject M is placed on the top 2. The surgeon clicks on an icon related to the selection of the examination method arranged in the icon display area R3, and transmits to the X-ray imaging apparatus 1 the mode of imaging to be executed from now. At this time, for example, if the surgeon clicks the chest imaging icon, a parameter data set relating to X-ray imaging conditions suitable for chest imaging is read from the parameter storage unit 16. Thus, the X-ray imaging apparatus 1 can know the parameters necessary for X-ray imaging all at once by simply clicking on the chest imaging icon. This parameter can be changed manually according to the operator's instruction. Thereby, the X-ray imaging apparatus 1 according to the first embodiment can perform imaging in accordance with the physique of the subject. The icons arranged in the icon display area R3 in this way function as setting change means for changing the set value of the X-ray tube 3.

  At this point, the screen D is as shown in FIG. That is, the surgeon has acquired a plurality of captured images of the subject M, and the previously captured X-ray image is reflected in the captured image display region R1 in FIG. And

  The surgeon confirms that the body movement of the subject M has settled, and presses the button 22a of the instruction input switch 22 to the first level. Then, the surgeon inputs a prior instruction to the X-ray imaging apparatus 1. The advance instruction notifies the X-ray tube 3 that X-ray irradiation is performed in advance, and the X-ray tube control unit 6 that has received the advance instruction sends the X-ray tube 3 an X-ray. Start preparation for irradiation.

  At this time, as shown in FIG. 4, the display unit 21 displays set values indicating the tube current of the X-ray tube 3, the tube voltage, the focus state of the X-ray tube 3, and the presence or absence of exposure correction performed by the exposure correction unit 12. It is displayed in region R4. At this point, the surgeon can clearly know the details of X-ray imaging to be performed.

  “120 kv” shown in FIG. 4 means a tube voltage of the X-ray tube 3, and “200 mA” means a tube current of the X-ray tube 3. Further, “40 msec” shown in FIG. 4 means an X-ray irradiation time. The “small focus” in FIG. 4 means a focus state in the X-ray tube 3. The X-ray tube 3 has a plurality of filaments, and is configured to output X-rays when electrons emitted from the filament hit the target. The output of the X-ray tube 3 can be adjusted by increasing or decreasing the number of filaments used. The small focus mode is suitable for imaging with a small output, and means, for example, X-ray irradiation using a single filament. “120 kv”, “200 mA”, “40 msec”, and “small focus” are examples of the setting of the radiation source according to the present invention.

  The set value display area R4 is overlapped with the captured image display area R1, and is also overlapped with the captured image non-display area. In this way, the set value display area R4 is displayed across both areas. Thus, the set value display region R4 is displayed in a large pop-up on the screen D across the boundaries of the regions R1 to R3 displayed on the screen D. Therefore, the surgeon can easily visually recognize this.

  An OK icon 26 that can be clicked by the surgeon is displayed in the OK icon region R5. The OK icon area R5 is provided inside the set value display area R4. However, this may be provided in the vicinity of the set value display region R4. By doing either, the surgeon can click the OK icon 26 without greatly moving the line of sight on the screen. When the cancel icon 27 (cancel input means) in FIG. 4 is clicked, the X-ray imaging apparatus 1 returns to the stage before the surgeon inputs a prior instruction. The OK icon corresponds to the confirmation input means of the present invention.

  After clicking the OK icon 26, the surgeon presses the button 22a of the instruction input switch 22 up to the second level. This operator's instruction means an actual instruction to actually irradiate X-rays. With this, the X-ray imaging apparatus 1 starts X-ray irradiation. Incidentally, when the surgeon gives an actual instruction without clicking the OK icon 26, the determination unit 13 invalidates the actual instruction and does not perform X irradiation by the X-ray tube 3. That is, after the OK icon 26 is displayed, the determination unit 13 stands by until the OK icon 26 is clicked. That is, the surgeon must always click the OK icon 26 before X-ray irradiation, and the set value display region R4 is visually recognized at that time. In this way, the X-ray imaging apparatus 1 can surely notify the operator of the irradiation conditions.

  X-rays transmitted through the subject M enter the FPD 4. The FPD 4 sends the detection data to the captured image generation unit 11. The X-ray image acquired in this way is displayed in the captured image display area R1 of the display unit 21. That is, a new X-ray image shown in FIG. 5 is displayed in the captured image display region R1 instead of the X-ray image displayed in FIG. At this time, as shown in FIG. 5, the set value display area R4 and the OK icon area R5 displayed in FIG. In this way, both regions R4 and R5 are configured not to interfere with the display of a new X-ray image. In this way, the operation of the X-ray imaging apparatus according to Embodiment 1 is completed.

  In addition, the appearance timing of the OK icon region R5 on the screen D is associated with that of the setting value display region R4. That is, the OK icon area R5 appears as a pop-up display on the screen D when the set value display area R4 appears on the screen D, and is erased from the screen D when the set value display area R4 is erased from the screen D. The The cancel icon 27 is the same as the OK icon 26.

  As described above, according to the first embodiment, the X-ray imaging apparatus 1 with excellent operability can be provided. That is, the X-ray imaging apparatus 1 according to the first embodiment includes an instruction input switch 22 that inputs an instruction to the X-ray tube 3. When an instruction is input to the instruction input switch 22, the display unit 21 The setting of the X-ray tube 3 such as the tube current and the tube voltage is displayed so as to overlap the captured image display region R1 on the screen. That is, a photographic image of the subject M is displayed in the photographic image display area R1 on the screen, and the setting of the X-ray tube 3 is displayed so as to overlap therewith. By doing in this way, even if the diagonal dimension of the screen is 21 inches or less, the setting of the X-ray tube 3 which is important information in the X-ray imaging is superimposed on the imaging image display region R1 on the screen. Will be displayed prominently. Therefore, the surgeon can perform X-ray imaging while reliably recognizing important information in X-ray imaging.

  Further, the setting of the X-ray tube 3 in the first embodiment is displayed larger by being displayed so as to protrude from the captured image display area R1 toward the captured image non-display area. Therefore, the surgeon can perform X-ray imaging while more surely recognizing important information in X-ray imaging.

  The instruction input switch 22 according to the first embodiment includes a prior instruction input switch 22 and an actual instruction input switch 22. In this way, by dividing the X-ray irradiation instruction into two stages, the X-ray imaging apparatus 1 can prepare in advance to irradiate the X-ray tube 3 with X-rays, thereby enabling smoother imaging. It becomes. In addition, the setting of the X-ray tube 3 is displayed on the screen when the prior instruction is input. Therefore, the surgeon can confirm the setting of the X-ray tube 3 before the X-ray is actually irradiated.

  Moreover, according to the structure of Example 1, the determination part 13 is provided. The determination unit 13 intervenes transmission of information between the instruction input switch 22 and the X-ray tube 3 and can invalidate the actual instruction. The determination unit 13 causes X-ray irradiation only when an actual instruction is given after confirmation input by the operator. Thereby, before an actual instruction | indication is performed, the period which makes the operator visually recognize the setting of the X-ray tube 3 can be given.

  The OK icon 26 is an operation icon displayed on the screen. Moreover, the OK icon 26 is displayed in or near the set value display area R4. Therefore, when the OK icon 26 is operated, the set value display region R4 is within the operator's field of view. Thus, the visibility of the setting of the X-ray tube 3 can be further improved.

  Further, the OK icon 26 is a configuration for allowing the operator to confirm the setting of the X-ray tube 3. Therefore, the OK icon 26 appears on the screen in accordance with the appearance of the setting of the X-ray tube 3 on the screen.

  Moreover, the diagonal dimension of the screen which the display part 21 has is 21 inches or less. If the display unit 21 is of this size, the display unit 21 can be easily installed even if the examination room in which the X-ray imaging apparatus 1 is installed is narrow.

  Further, the present invention is not limited to the above-described configuration, and can be modified as follows.

  (1) Although the above-described configuration is configured to display the OK icon 26 on the screen D, the present invention is not limited to this. That is, the determination unit 13 invalidates the actual instruction and causes the X-ray tube 3 to perform X-ray irradiation when an actual instruction is given within the standby time starting from the time when the prior instruction is input. There may be no configuration. Thus, the set value is displayed on the screen D during the standby time. The standby time is stored in the time storage unit 15 in FIG. According to the configuration of the present modification, the determination unit 13 performs X-ray irradiation only when an actual instruction is given after the standby time has elapsed. Thereby, before an actual instruction | indication is performed, the period which makes the operator visually recognize the setting of the X-ray tube 3 can be given.

  (2) In the case where the above modification is adopted, as shown in FIG. 6, a countdown indicating the remaining time until the actual instruction becomes valid may be displayed on the image D during the standby time period. . As a result, the surgeon can clearly know the elapse of the standby time by counting down, and can provide the X-ray imaging apparatus 1 with more excellent operability. In FIG. 6, the area where the countdown is displayed is provided in the set value display area R4. However, this may be provided in the vicinity of the set value display region R4.

  (3) Each of the above-described embodiments is a medical device, but the present invention can also be applied to industrial and nuclear devices.

  (4) The X-ray referred to in each of the above-described embodiments is an example of radiation in the present invention. Therefore, the present invention can be applied to radiation other than X-rays.
