JP-A-2-174098

However, in the case of the conventional example, an area for confirming the number of images and an area for operating the divided composite image are displayed even though the divided composite image is not created. For this reason, information that the operator does not need to see is displayed, which may hinder thinking.
In addition, since the area for confirming the number of images and the area for operating the divided composite image are always displayed, necessary information is hidden, visibility is lowered, and the burden on the operator is reduced. It was.

  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to the following embodiment, It shows only the specific example advantageous for implementation of this invention. In addition, not all combinations of features described in the following embodiments are indispensable as means for solving the problems of the present invention.

  1 is an overall side view of an X-ray imaging apparatus according to Embodiment 1 of the present invention. This X-ray apparatus includes an X-ray generator 1000, an X-ray tube 1001, a console 1002, an X-ray detector 1003, an X-ray controller 1004, and a display 1005. The X-ray control apparatus 1004 includes an I / F 1006, a CPU 1007, a RAM 1008, an HDD 1009, a divided imaging program 1010, an input unit 1011 and an output unit 1012.

  Here, the X-ray generator 1000 irradiates the subject H with X-rays using the X-ray tube 1001. In particular, the X-ray generator 1000 is operated by the console 1002. X-rays irradiated from the X-ray tube 1001 and transmitted through the subject H are detected by an X-ray detector 1003 which is a flat panel X-ray detector (FPD). The X-ray detector 1003 detects radiation generated from the radiation generator 1000 and obtains a radiation image. The X-ray imaging image obtained by the X-ray detector 1003 is notified to the X-ray imaging control apparatus through the I / F 1006.

  In addition, the X-ray control apparatus 1004 performs divided imaging by developing the divided imaging program 1010 held in the HDD 1009 in the RAM 1008. Here, the division imaging is an imaging method for capturing images of a plurality of X-rays and outputting them as a single image. For example, in the case of 2 × 2 divided imaging, radiographic images corresponding to four small areas are captured, and when output, the four images are arranged in a 2 × 2 layout and output as one image. Is done. At the time of radiographic image capture corresponding to each small area, radiography is performed by narrowing the irradiation field to the area corresponding to the small area. FIG. 2 is a diagram showing functional blocks realized by the divided photographing program 1010. As shown in FIG. The divided photographing program 1010 includes a program module corresponding to each function of the photographing control unit 2000, display control unit 2002, divided format designation unit 2003, and divided composite image creation unit 2004, and a GUI module corresponding to the divided composite image operation UI 2006. And are included.

  Here, the imaging control unit 2000 controls X-ray imaging. An X-ray image 2005 received by the I / F 1006 after X imaging is recorded in the recording unit 2001, and the display control unit 2002 displays the X-ray image 2005 on the display 1005 connected to the X-ray control apparatus 1004 (FIG. 3 (a)).

  The division format designation unit 2003 can designate the division format of the divided composite image by the input unit 1011 of the X-ray control apparatus 1004. Here, the format is information that defines the layout of an image obtained by divided shooting, and defines a layout of 2 × 1, 1 × 2, for example. The input unit 1011 can be implemented using the GUI displayed on the display 1005, but the method of specifying the division format is not limited to this.

  When the division format is designated by the division format designation unit 2003, the designated format is clearly displayed on the display 1005, and division photographing is started (FIG. 3B).

  After that, when an X-ray image that matches the number of frames in the format specified by the divided format specifying unit 2003 is recorded by the recording unit 2001, the X-ray image recorded in the recording unit 2001 by the divided composite image creating unit 2004 is used. Create split composite images.

  The created divided composite image is output to the display 1005 by the display control unit 2002. In this respect, the display control unit 2002 also functions as an output unit that collectively outputs radiographic images captured according to the format as one image. In addition, a communication unit that outputs an image to an external server such as PACS is also included in the category of the output unit.

  In another embodiment, it is not always necessary to synthesize a plurality of images, and it is only necessary to output a single image arranged in a format specified by a division format.

  Further, the display control unit 2002 displays the divided composite image held in the recording unit 2001 when, for example, at least one divided composite image is generated by the divided composite image generation unit 2004 according to the progress of the divided shooting. An operation UI (GUI) 2006 for operation is displayed on the display 1005 (FIG. 3C). After that, it is possible to operate the number of created divided composite images and the divided composite image in the operation area of the divided composite image operation UI 2006 displayed on the display 1005. The operation herein includes an operation of switching between a display form in which the divided composite image is simultaneously displayed in a specific display area and a display form in which the radiation images obtained by individual imaging are displayed one by one. For example, when 2 × 2 divided imaging is instructed and a total of four radiographic images are obtained, a display form in which the four radiographic images are collectively displayed according to the format, and a layout defined by the format Buttons for switching the display form for individually displaying the upper right, lower right, upper left, and lower left images. When such a button is repeatedly pressed, the display control unit 2002 switches the display of a specific display area so as to display the entire, upper right, lower right, upper left, and lower left images, respectively. This facilitates detailed confirmation of the divided images.

  In addition to the above-described buttons, the number of times of divided photographing is displayed for each divided photographing format, so that, for example, when the number of photographing corresponding to each format is predetermined in medical examinations of the abdomen, etc. The number of times of imaging in one unit examination for each patient can be easily notified.

  Such a GUI 2006 is useful when manipulating an image obtained by divided shooting, but is not necessary for normal shooting. Therefore, the GUI 2006 is displayed only when it is necessary from the viewpoint of effective use of the screen area. I am going to do that.

  Note that various timings for displaying the GUI 2006 may be considered depending on the situation.

  For example, if the display control unit 2002 displays the GUI 2006 at the timing when divided shooting is instructed, the photographer can be notified more effectively that the divided shooting mode is set as the display screen. Also, for example, when the divided shooting mode and other modes can coexist explicitly, the display control unit 2002 displays the GUI 2006 at the timing when the format is specified by the divided format specifying unit 2003. The GUI 2006 can be displayed at the timing when divided shooting is performed, and the display area can be used effectively.

  Alternatively, it may be possible to specify the division format in advance and perform normal shooting first. For example, in such a case, by displaying the GUI 2006 in response to one radiographic image being taken as the divided shooting, the situation in which the GUI 2006 is displayed at the timing when the divided shooting is not performed is reduced.

  In addition, immediately after one image is taken, there is little inconvenience in that each image is browsed even if it is coexisting with normal photography. Therefore, by displaying the GUI 2006 in response to a plurality of radiographic images being captured as divided imaging, the GUI 2006 can be displayed only at a timing that may be necessary, and the display area can be used more effectively.

  In another example, in response to a workflow in which each image is viewed in detail after imaging for one division format is completed, the display control unit 2002 displays all radiographic images for one designated format. The GUI 2006 is displayed on the display 1005 in response to the shooting. In this way, the display area can be used efficiently along the work flow.

  In another example, it is conceivable that shooting is repeated, the division format is specified at the timing of output or browsing, and the images are displayed or output side by side in a layout defined by the format. In response to such a case, the display control unit 2002 causes the display 1005 to display the GUI 2006 in response to the application of the specified format to the captured radiographic image. Thereby, it is possible to appropriately display the GUI in a scene where it is necessary to operate the divided images.

  In the above example, the display control is performed when the GUI 2006 is transitioned from the non-display state to the display state. However, the display control unit 2002 also performs control for changing the GUI 2006 from the display state to the non-display state according to the situation. For example, when divided shooting and normal shooting are sequentially performed, the GUI displayed on the display unit is not displayed in response to an instruction to perform shooting that is not divided shooting. In this way, for example, the GUI 2006 can be displayed only at a necessary timing in a situation such as an abdominal medical examination in which divided imaging and normal imaging are used together for one patient. The area can be used effectively.

  In particular, when a display screen as shown in FIG. 3 is used, the effect is remarkable. As shown in FIG. 3A, the display control unit 2002 sequentially displays reduced images (thumbnail images) of a plurality of radiation images in the examination information display area (first display area) 3003 on the imaging screen 3001 according to the imaging. Display. In addition, a designated radiographic image among a plurality of radiographic images corresponding to each of the reduced images designated in the captured image display area (second display area) 3002 is displayed. Then, the GUI 2006 is displayed so as to overlap the lower part of the second display area 3002 (position shown in FIG. 3B). By displaying the GUI 2006 in such an area, the captured image display area 3002 is enlarged to facilitate detailed confirmation.

  As described above, when the display area of the reduced image and the display area of the GUI 2006 overlap, the display area can be efficiently used by displaying or not displaying the GUI 2006 according to the progress of the divided shooting. .

  In addition, there may be a case where an output unit for outputting an image or a divided image captured as described above to an external server is provided, or a reduced image is not displayed when an image captured once is lost. Alternatively, even if the reservation is canceled after the divided shooting format is specified and the shooting reservation is made, the display related to the divided image may disappear from the reduced image area. In response to such a case, the display control unit 2002 hides the GUI 2006 displayed on the display 1005 in response to the fact that the reduced image 3004 corresponding to the divided shooting does not exist in the first display area 3003. To do. In this way, priority can be given to the display of reduced images.

  On the other hand, for example, in an abdominal examination, since a plurality of photographing including divided photographing are performed, there are cases where the reduced image cannot be displayed in the examination image display area 3001. Therefore, if the display area is smaller than the divided composite image operation UI 2006 when the divided composite image operation UI 2006 is displayed, the display area of the captured image thumbnail display area 3004 is reduced at the display timing of the divided composite image operation UI 2006. An area in which the captured image thumbnail cannot be displayed because the captured image thumbnail display area 3004 is made small can be displayed using the scroll bar 3007. As described above, when the reduced image of the radiographic image corresponding to the divided imaging is displayed in the specific display area at the timing when the GUI 2006 is displayed in the specific display area by the display control unit 2002, the display control is performed. The unit 2002 displays the GUI 2006 in a specific area and controls the display position of the reduced image so that the reduced image is displayed in an area outside the specific display area. Accordingly, the divided composite image operation UI 2006 is displayed in the limited display area of the display 1005 at the timing when the divided composite image is created in order to improve the visibility of the operator as much as possible.

  In another example, the display control unit 2002 can control the display timing of the GUI 2006 according to the number of reduced images displayed in the first display area 3003. For example, when the number of reduced images is larger than the threshold, the GUI 2006 displays the images according to the fact that all the divided images for a specific format have been captured, and maintains the display area of the reduced images as much as possible. To do. On the other hand, when the number of reduced images is smaller than the threshold value, it is considered that the burden on the operator is small even if the GUI 2006 is displayed. Therefore, at the timing at which division shooting is instructed or the timing at which division format is specified. The GUI 2006 is displayed.

  In addition, it is not always necessary to automatically pop up the GUI 2006 in a situation where predetermined imaging is sequentially performed on each subject and diagnosis is performed at another place or by another person in charge. sell. Corresponding to such a case, a setting unit is provided for setting whether or not to display the GUI 2006 according to the progress of the divided shooting. For example, the setting unit acquires a user operation input from the input unit 1011 or the like, and sets whether to automatically pop up the GUI 2006 according to the user operation. This makes it possible to provide a simple and convenient GUI without displaying a GUI unnecessary for shooting work on the screen.

  In response to the need to manually display the GUI 2006 in the above-described situation, for example, a GUI (second GUI) for instructing display or non-display of the GUI 2006 (first GUI) on the display screen is displayed. It is displayed according to the control of the display control unit 2002.

  For example, the second GUI displays a GUI for displaying the second GUI by designating a specific button or icon on the screen by an operation from the input unit 1011. Thereby, the user can display / hide the GUI for operating the divided captured images at a necessary timing.

  In another example, the display control unit 2002 causes the second GUI to be displayed according to the progress of the divided shooting. Since the second GUI generally has a larger display area than the first GUI 2006, the second GUI occupies less display area and can be displayed with one click at the required timing. Alternatively, the display control unit 2002 can display the second GUI in a non-selectable state in advance, and make a transition to a selectable state according to the progress of the divided shooting. It is possible to reduce the problem that the user makes an erroneous selection at a timing other than when it is in a selectable state.

  In yet another example, the display control unit 2002 gives priority to the GUI 2006 according to the progress of divided shooting over GUIs such as image processing parameter adjustment, distance measurement tool in the image, and rotation inversion tool different from the GUI 2006. Can be displayed. For example, the display order in the vertical direction of the screen is changed so that the GUI 2006 is positioned above the other GUIs at the timing when a plurality of shootings corresponding to a specific divided shooting format are performed. In this way, the GUI 2006 that may be necessary can be displayed with priority at an appropriate timing.

  The flow of Example 1 is shown in the flowchart of FIG. First, inspection is started in S1001. In step S1002, a shooting screen is displayed. When the shooting is ready, a general thumbnail is displayed instead of a thumbnail for split shooting in step S1003.

  In step S1004, it is determined whether a division format is designated by the division format designation unit 2003. If the division format is designated, the general thumbnail displayed in S1003 is changed to a divided thumbnail in S1005. In step S1005, divided shooting is started. However, if the division format is not designated in S1004, general X-ray imaging is started in S1006. When imaging is performed in S1006, the X-ray imaging image 2005 acquired in S1007 is recorded in the recording unit 2001.

  In step S1008, the presence / absence of a divided composite image is checked. If at least one divided composite image is created by the divided composite image creation unit 2004, a divided composite image operation UI 2006 is displayed in S1009, and it is determined in S1011 whether the inspection is finished. However, if a divided composite image has not been created by the divided composite image creation unit 2004, it is determined in S2010 whether or not divided shooting is in progress. If it is in the middle of divided shooting, shooting is continued in S1006. If it is not divided shooting, it is determined in step S1011 whether or not the inspection is completed.

  Finally, it is determined whether or not the inspection is completed in S1011, and if the inspection is not completed, the general thumbnail is displayed again in S1003. If the inspection is completed, the inspection is terminated in S1022 and the imaging screen is hidden.

  The overall side view of the second embodiment is the same as that of the first embodiment. FIG. 4 is a detailed side view when the divided photographing program 1010 is developed. The divided photographing program 1010 includes a photographing control unit 2000, a recording unit 2001, a display control unit 2002, a divided format designation unit 2003, and a divided composite image creation unit 2004. Further, the X-ray generation apparatus 1000 as an external device is provided with an external division format designation unit 4001 and a division format transmission unit 4002. Further, a console 1002 (FIG. 6) for designating a division format is provided.

  Here, the imaging control unit 2000 controls X-ray imaging. An X-ray image 2005 received by the I / F 1006 after X imaging is recorded in the recording unit 2001, and the X-ray image 2005 is displayed on the display 1005 connected to the X-ray control apparatus 1004 by the display control unit 2002.

  In the X-ray generator 1000, the division format is designated on the console 1002. However, the division format designation method is not limited to this. When the division format is designated, the division format transmission unit 4002 notifies the division format reception unit 4003 of the X-ray control apparatus 1004. The control when the division format is notified is the same as in the first embodiment.

  The flow of Example 2 is shown in the flowchart of FIG. The difference from the first embodiment is that the division format is designated at the console 1002 of the X-ray generation apparatus 1000 in S1004.

  The third embodiment has the same configuration as that of the first embodiment. In the third embodiment, the display control unit 2002 displays the divided composite image operation UI 2006 at the timing when at least one X-ray image 2005 constituting the divided composite image is recorded in the recording unit 2001. Alternatively, the divided composite image operation UI 2006 is displayed at the timing when the division format is designated by the division format designation unit 2003.

  The fourth embodiment has the same configuration as that of the second embodiment. In the fourth embodiment, the display control unit 2002 displays the divided composite image operation UI 2006 at the timing when the divided format receiving unit 4003 receives the divided format. However, when the non-divided format is received again in a state where no divided composite image has been created thereafter, the divided composite image operation UI 2006 is hidden.

  The fifth embodiment has the same configuration as that of the first or second embodiment. In the fifth embodiment, the display control unit 2002 hides the divided composite image operation UI 2006 when the divided composite image is deleted such as a copy failure and at least one divided composite image does not exist.

  As described above, according to the embodiment of the present invention, the area for confirming the number of images and the area for operating the divided composite image are displayed at the timing when at least one divided composite image is created. . By doing so, it is intended to improve visibility and reduce the burden on the operator.
