Description

  The present invention relates to an image processing system and an image processing method for performing processing for arranging an image in an output region corresponding to an output device, and a program for causing a computer to execute the image processing method.

  In recent years, a technique for digitally detecting and generating an X-ray image using a sensor such as a flat panel sensor has become widespread as an X-ray image capturing apparatus (radiation image capturing apparatus) for medical diagnosis. An X-ray digital image obtained by the X-ray imaging apparatus (hereinafter, the X-ray digital image is simply referred to as “X-ray image”) is subjected to various correction processes and computer processing such as image processing. Thereafter, it is output on a monitor, film, etc., and a doctor's diagnosis is performed.

  In addition, an X-ray image output mode at the time of diagnosis uses either a life size output that is output at the image size on the sensor or a fixed reduction rate output that is output at a constant reduction rate. Moreover, since the reduction rate change according to the output area corresponding to the output device is difficult to diagnose and leads to misdiagnosis, it is not generally performed.

  The size of the output area varies depending on the performance of an output device such as a monitor or a film. Therefore, depending on the selected output device and the height and body shape of the subject, the observation area in the X-ray image may not fit within the size of the output area. At that time, for example, a method of cutting out an X-ray image and outputting an appropriate observation area is known (for example, see Patent Document 1 below).

  Specifically, in Patent Document 1, the irradiation field area size is compared with the output area size corresponding to the output device, and the user is alerted when the irradiation field area size is large. In addition, the maximum size frame of the output area and the frame to be output to the output device are displayed on the X-ray image together with the frame of the irradiation field area, thereby assisting the clipping operation.

  Further, when the size of the observation area is small, it is cost efficient to arrange and output a plurality of images in an output area of a certain size. And, for example, as a method of efficiently arranging more images in the output area, if a plurality of images of arbitrary size cannot be arranged in the output area, the periphery of the image is determined based on the arrangement area / width of the image. It is known that a part is deleted and rearranged (for example, refer to Patent Document 2 below).

JP 2006-296554 A Japanese Patent No. 3854766

  By the way, in the case where a plurality of arbitrary X-ray images are sequentially cut out and arranged in an output area of a certain size corresponding to the output device, the areas that can be cut out differ depending on the empty area for the output area. In addition, when one or more images have already been arranged, there may be a plurality of empty areas that can be arranged depending on the cutout range.

  In the conventional method according to Patent Document 1 described above, the maximum size frame of the irradiation field area and the output area is displayed on the X-ray image, thereby assisting in setting the clipping range. This is efficient for the cutout operation when arranging one observation region in an output region of a certain size, but the cutout operation when arranging a plurality of observation regions is not considered. For this reason, the cut-out operation when arranging a plurality of observation areas in an output area of a certain size becomes complicated, and there is a problem that work efficiency decreases.

  In addition, in the conventional method according to Patent Document 2 described above, when a plurality of images of an arbitrary size are arranged in an output region of a certain size, the periphery of the image is deleted and rearranged according to the amount of protrusion of the image. ing. For this reason, there is a possibility that an area that is different from the observation area specified by the user is output and an area necessary for diagnosis is deleted.

  The present invention has been made in view of the above-described problems, and when arranging a plurality of images in an output area corresponding to an output device, the operator's operability is improved and an appropriate observation environment is ensured. It is an object of the present invention to provide an image processing system, an image processing method, and a program which are realized.

  The image processing system of the present invention is an image processing system that performs processing for arranging an image in an output region corresponding to an output device, and includes an outputable region calculation unit that calculates an outputable region of an image with respect to the output region, Based on the first input means for inputting the cutout start position of the image, the outputable area calculated by the outputable area calculation means, and the cutout start position input by the first input means, the cutout possible area is determined. A cuttable area calculating means for calculating, a cuttable area display means for displaying the cuttable area calculated by the cuttable area calculating means on the image together with the image, and the first input means.

And image placement means for placing the image on the output area.

When this cutout start position 451 is designated, the preview image display unit 450 displays cutable areas 452 and 453 and noncuttable areas 454 and 455. Specifically, in the preview image display unit 450, the croppable areas 452 and 453 and the uncuttable areas 454 and 455 are displayed with different background colors.

  When the next button 470 is operated by the operator, the process proceeds to the next process. When the output image button 480 is operated by the operator, the confirmed output image confirmation screen 500 (FIG. 5) and the output image confirmation screen 600 (FIG. 6) are displayed on the operation / display unit 116.

The output image confirmation screen 600 shown in FIG. 6 is an output image display in which an X-ray image 611 is added to the output image display unit 510 (more specifically, the empty area 511) of the output image confirmation screen 500 shown in FIG. Part 610 is shown. Similar to the output image confirmation screen 500 shown in FIG. 5, an output device information display unit 620 that displays detailed information of the output device is displayed on the output image confirmation screen 600 shown in FIG. 6. Further, the output image confirmation screen 600 shown in FIG. 6 is provided with an OK button 630 as in the case of the output image confirmation screen 500 shown in FIG. 5, and when this OK button 630 is operated (pressed), FIG. Returning to the cutout area setting screen 400 shown in FIG.

  Next, the overall processing flow of the X-ray image processing system 100 according to the first embodiment will be described with reference to FIGS.

  For example, when the patient 200 completes the outpatient reception and, for example, it is determined by the doctor's diagnosis that X-ray images of the chest front and the side of the chest are necessary, the patient 200 moves to the X-ray imaging room. Then, the examination order issued by the doctor is transmitted to the X-ray imaging control unit 115 via the RIS 130. The radiologist (operator) selects an examination order for the patient 200 from the display screen of the operation / display unit 116, and starts imaging (imaging order) related to the examination order.

  When an irradiation button (not shown) is pressed by a radiologist (operator), the X-ray generation control unit 112 is controlled by the X-ray generation unit 111 to X-rays according to the imaging conditions from the X-ray image imaging control unit 115. Is generated. The sensor 113 detects the X-ray transmitted through the patient 200 as an electrical signal (charge), and the sensor unit 114 performs A / D conversion on the charge corresponding to the transmitted X-ray dose of the patient 200 detected by the sensor 113. This is transferred as an X-ray image to the X-ray image capturing control unit 115.

  Then, the X-ray image transferred from the sensor unit 114 is read into the image input unit 210 of the X-ray image capturing control unit 115-1 shown in FIG.

  After that, the image processing unit 220 shown in FIG. 2 performs predetermined image processing such as preset correction processing, gradation processing, and frequency processing on the X-ray image read from the image input unit 210. Thereafter, the X-ray image subjected to the image processing by the image processing unit 220 is displayed on the display screen of the operation / display unit 116 (for example, the clipping region setting screen 400 shown in FIG. 4). Thereafter, the radiologist (operator) designates the cutout range of the output X-ray image using the cutout region setting screen 400 shown in FIG. 4 displayed on the operation / display unit 116, for example. The cutout control process by the cutout control unit 230 (FIG. 2) when the cutout range is designated will be described with reference to FIGS.

  First, the free space calculation unit 231 acquires output device information such as a size and a pixel pitch related to an output device set as an output destination from the output device information holding memory 240. For example, when the output device of the output destination is set to the printer 1, as the output device information of the printer 160-1 corresponding to the printer 1, for example, the pixel pitch is 80 μm, the film size width is 4268 pixels, and the height is Information such as 5108 pixels is acquired.

  Furthermore, the empty area calculation unit 231 acquires image arrangement information such as the image size and arrangement position of the X-ray image currently arranged in the output area from the image arrangement information holding memory 250. Here, for example, one X-ray image has already been arranged, the width of the cut-out size is 2000 pixels, the height is 1400 pixels, and the start point (X, Y) of the arrangement position is the upper left. The information such as (0, 0) is acquired using as the origin.

  In step S101 of FIG. 3, the free space calculation unit 231 outputs the output based on the output device information acquired from the output device information holding memory 240 and the image arrangement information acquired from the image arrangement information holding memory 250. Free space for the area is calculated. Here, for example, when the output device of the output destination is set to the printer 1 (printer 160-1), the output region is an output region corresponding to the printer 1, and is based on the output device information.

  In this case, the output area of the printer 1 (printer 160-1) is a size obtained by multiplying the pixel pitch by the number of effective pixels, and is vertical (height) 408.64 mm × horizontal (width) 341.11 mm. In the above-described example, the arranged image size is vertical (height) 224 mm × horizontal (width) 320 mm, so the free area is 184.64 mm long × 341.11 mm wide (empty area 511 in FIG. 5) or The height is 408.64 mm × width 21.11 mm (empty area 512 in FIG. 5).

  As a result of acquisition from the image arrangement information holding memory 250, when there is no image already arranged in the output area, the free area calculation unit 231 applies the output device acquired from the output device information holding memory 240 to the output device. The corresponding output area is calculated as a free area.

  Thereafter, when the radiologist (operator) designates the cutout start position 451 on the cutout area setting screen 400 illustrated in FIG. 4, the cutout start position input unit 260 extracts the information of the cutout start position 451 from the cutout area calculation unit 232. Enter against.

  Subsequently, in step S102 of FIG. 3, the clippable area calculation unit 232 selects a clippable area based on the cutout start position information input from the cutout start position input unit 260 and the empty area calculated in step S101. calculate. For example, when the cutout start position (X, Y) is (0,400), the cutout area has a width of 21.11 mm, a height of 344.64 mm (cutoutable area 452 in FIG. 4), and a width of 341. 11 mm and a height of 184.64 mm (the cutable area 453 in FIG. 4).

  Subsequently, in step S103 in FIG. 3, the X-ray image capturing control unit 115 (for example, the cutout area calculation unit 232) displays the cutout area calculated in step S102 as the operation / display unit 116 (cutout area in FIG. 4). On the setting screen 400). Specifically, in step S103, the preview image display unit 450 shown in FIG. 4 displays the clippable areas together with the X-ray image as clippable areas 452 and 453 on the X-ray image, and visualizes them (can be clipped). Area display step).

  At this time, the X-ray image capturing control unit 115 sets the uncuttable regions 454 and 455 on the X-ray image other than the cutable regions 452 and 453 shown in FIG. Are displayed separately (identified). The method for distinguishing (identifying) and displaying the cuttable areas 452 and 453 and the noncuttable areas 454 and 455 shown in FIG. 4 is not limited to this mask, and other methods may be used.

  Thereafter, when the radiologist (operator) designates the cutout end position with reference to the cutout start position 451 on the cutout area setting screen 400 shown in FIG. 4 and designates the cutout area, the cutout area input unit 270 Input information about the cut-out area. Specifically, the cutout area input unit 270 inputs information about the cutout area to the image size changing unit 233 and the image placement unit 234.

  Here, it is conceivable that the cutout start position input unit 260 and the cutout region input unit 270 described above are configured by a pointing device such as a mouse, for example. In this case, for example, the cutout start position input unit 260 inputs information on the coordinates using the first right click of the mouse by the radiologist (operator) as the cutout start position. The cutout area input unit 270 cuts out a rectangular area from the cutout start position designated by the first right click to the cutout end position clicked for the second time by the second right click of the mouse by the radiologist. The coordinates information is input as the area.

  Subsequently, in step S104 of FIG. 3, for example, the image size changing unit 233 has the cutout area size input from the cutout area input unit 270 within the cutout possible range based on the cutout area calculated in step S102. Determine whether or not.

  As a result of the determination in step S104 in FIG. 3, when the size of the cutout area input from the cutout area input unit 270 is within the cuttable range, the process proceeds to step S105 in FIG.

  When the processing proceeds to step S105 in FIG. 3, the image size changing unit 233 uses the size of the cutout area input from the cutout area input unit 270, that is, the size of the cutout area specified by the radiologist (operator). Change the image size of the line image. Here, the information on the set image size is held in the image arrangement information holding memory 250. Then, the X-ray image capturing control unit 115 (for example, the clipping control unit 230) sets the clipping frame with the image size changed by the image size changing unit 233, that is, the size of the clipping region designated by the radiologist (operator). This is displayed on the cutout area setting screen 400 shown in FIG. Thereafter, the process proceeds to step S107 in FIG.

  On the other hand, as a result of the determination in step S104 in FIG. 3, if the size of the clip region input from the clip region input unit 270 is not within the clippable range (that is, out of the range), the process proceeds to step S106 in FIG. move on.

  When the process proceeds to step S106 in FIG. 3, the image size changing unit 233 invalidates the cutout area from the cutout area input unit 270, and uses the maximum size of the cutout area based on the cutout area calculated in step S102. Change the image size of the line image. Here, the information on the set image size is held in the image arrangement information holding memory 250. Then, the X-ray image capturing control unit 115 (for example, the clipping control unit 230) sets the clipping frame with the image size changed by the image size changing unit 233, that is, the maximum size of the clipable range shown in FIG. It is displayed on the screen 400. Thereafter, the process proceeds to step S107 in FIG.

  When the processing proceeds to step S107 in FIG. 3, the image arrangement unit 234 arranges the X-ray image cut out in step S105 or step S106 in an empty area where the output area can be arranged (for example, arrangement of the X-ray image 611 in FIG. 6). Display: Image display step).

  Note that the radiographer (operator) appropriately depresses the output image button 480 shown in FIG. 4 before and after designating the cutout region, and the X-ray imaging control unit 115 detects this and confirms the output image. Screens 500 (FIG. 5) and 600 (FIG. 6) are displayed on the operation / display unit 116. Then, the radiologist (operator) refers to the output image confirmation screen displayed on the operation / display unit 116 and confirms information such as whether an observation area necessary for diagnosis is included or how much is an empty area. In addition, the timing for designating the cut-out area may be performed for each imaging order or collectively after all imaging orders in one inspection order are completed. In addition, X-ray images arranged in one output area can be set to a plurality of cutout areas on the same image as well as different images.

  Here, when setting a plurality of cutout regions on the same image, the radiologist (operator) presses a new button of the cutout processing button 463 shown in FIG. 4, and the X-ray image capturing control unit 115 Based on this operation, a clipping region addition process is performed. Further, when changing or deleting the cutout region, the radiologist (operator) selects a target cutout frame from the preview image display unit 450 and presses the change button or the delete button of the cutout processing button 463. Based on this operation, the X-ray image capturing control unit 115 performs cutout area change processing and deletion processing.

  Then, when all the X-ray images output by the processing of the clipping control unit 230 are arranged in the output area, the image output unit 280 sets X-ray image data based on the X-ray image to the designated output device. Is output.

  As described above, in the first embodiment, when the operator specifies a cutout area, it is possible to visualize the cutout area according to the empty area for the output area and the cutout start position specified by the operator. The burden of the operator's cut-out operation can be reduced. In addition, by arranging an X-ray image of an appropriate image size in the output area, the operator can proceed with the operation while confirming the output image, and the X-ray image is cut out in an image area not intended by the operator. This can be prevented. Furthermore, since it is possible to prevent the cutout area from being specified in a size larger than the cutout area, it is possible to reduce the repetition of the cutout area setting operation.

  Therefore, according to the first embodiment, when a plurality of images are arranged in the output area corresponding to the output device, it is possible to improve the operability for the operator and secure an appropriate observation environment. Become.

Enter the clipping information. The cutout information input by the cutout information input unit 710 is stored in the cutout information holding memory 720.

  The cutout control unit 730 controls the cutout of the X-ray image based on the cutout area calculation method set in the cutout information holding memory 720.

  First, the free area calculation unit 731 obtains a cutout area calculation condition from the cutout information holding memory 720, such as whether the rotation of the cutout image is valid or the rotation of the output area is valid. The rotation here means a 90-degree rotation. Furthermore, the free area calculation unit 731 acquires the output device information of the output destination from the output device information holding memory 240 and the image arrangement information of the X-ray image already arranged in the output area from the image arrangement information holding memory 250, A free area is calculated based on these information and calculation conditions.

  The cutable area calculation unit 732 can cut out a cutable area based on the information on the free area calculated by the free area calculation unit 731 and the information on the cutout start position input from the cutout start position input unit 260. Calculate the area. At this time, the X-ray image radiographing control unit 115 (for example, the cutout area calculation unit 732 of the cutout control unit 730) acquires information such as line types and display conditions from the cutout information holding memory 720, and selects the cutout area. It is displayed on the operation / display unit 116.

  The image size changing unit 733 is an appropriate cutout area based on the cutout area input from the cutout area input unit 270 or the cutout area calculated by the cutout area calculation unit 732, and sets the image size of the X-ray image. change. Then, the image size changing unit 733 saves the image size information in the image arrangement information holding memory 250 and outputs the image size information to the image arrangement unit 734.

  The image placement unit 734 determines the placement position of the X-ray image (cutout image) with respect to the output region based on the image size information from the image size changing unit 733 and the cutout region information from the cutout region input unit 270. At this time, if there are a plurality of arrangeable areas, the image arrangement unit 734 acquires the priority information of the arrangement areas from the cutout information holding memory 720, and arranges the X-ray image (cutout image) for the output area. Determine the position. Then, the image placement unit 234 stores the determined placement position information of the clipped image in the image placement information holding memory 250.

A control unit 914 is also provided. Further, in the setting screen 900 shown in FIG. 9, when the cancel button 920 is pressed, the changed setting becomes invalid, and when the OK button 930 is pressed, the changed screen is reflected on the original screen. Return to.

  FIG. 10 is a schematic diagram illustrating an example of a setting screen 1000 displayed on the operation / display unit 116 illustrated in FIG. 1 according to the second embodiment of this invention. Specifically, FIG. 10 shows a cutout area setting screen 1000.

  A setting screen 1000 shown in FIG. 10 displays a message display unit 1010 for instructing the next operation, a patient information input unit 1020 for inputting patient information, and various information (X-ray parameters) regarding the X-ray generation unit 111. An X-ray parameter display unit 1030 is provided. Further, the setting screen 1000 includes a thumbnail image display unit 1040 that displays an acquired image, a preview image display unit 1050 that displays a preview of the acquired image, and an image processing parameter change unit that changes an image processing parameter of the selected image. 1060 is also provided. Further, the setting screen 1000 is provided with a next button 1070 and an output image button 1080.

  The image processing parameter changing unit 1060 is switched by the tab 1061 for each type of image processing, and the example shown in FIG. 10 shows a case where “geometric” processing such as inversion or rotation is selected. In the case of this “geometry” processing, for example, a rotation / reverse button 1062, a cutout processing button 1063, and a control unit 1064 for switching display of a cutout area frame are provided. Based on the selection by the control unit 1064, the cutout area frame is reflected and displayed on the preview image display unit 1050.

  In the preview image display unit 1050, the cutout start position 1051 is a cutout start position designated by the operator. When the cutout start position 1051 is designated, the preview image display unit 1050 displays cutable areas 1052, 1053, 1054, and 1055, and uncuttable areas 1056 and 1057. Specifically, in the preview image display unit 1050, the croppable areas 1052, 1053, 1054, and 1055 and the uncuttable areas 1056 and 1057 are displayed with different background colors.

  When the operator operates the next button 1070, the process proceeds to the next process. When the output image button 1080 is operated by the operator, a confirmed output image confirmation screen is displayed on the operation / display unit 116.

  FIG. 11 shows a second embodiment of the present invention, and a screen 1110 showing an empty area when the output area is not rotated and an empty area when the output area is rotated, which are displayed on the operation / display unit 116 shown in FIG. It is a schematic diagram which shows an example of the screen 1120 which shows an area | region.

  Here, FIG. 11A shows a screen 1110 showing empty areas (1111 and 1112) when the output area is not rotated, and FIG. 11B shows empty areas (1121 and 1122 when the output area is rotated). A screen 1120 showing) is shown.

  Next, the overall processing flow of the X-ray image processing system 100 according to the second embodiment will be described with reference to FIGS. 1 and 7 to 11.

  Also in the second embodiment, since the flow from when the patient 200 receives a diagnosis by a doctor and when imaging is performed is the same as that of the first embodiment, the description thereof is omitted. The radiologist (operator) designates the cutout range of the output X-ray image using the cutout region setting screen 1000 shown in FIG. 10 displayed on the operation / display unit 116, for example. The cutout control processing by the cutout control unit 730 (FIG. 7) when the cutout range is designated will be described with reference to FIGS.

  First, the free area calculation unit 731 obtains a cutout area calculation condition from the cutout information holding memory 720, such as whether the rotation of the cutout image is valid or the rotation of the output area is valid. Here, the cut-out area calculation condition can also be referred to as a free area calculation condition. Here, it is assumed that both rotations are set to be valid. Also, the free space calculation unit 731 acquires output device information such as a size and a pixel pitch related to the output device set as the output destination from the output device information holding memory 240. For example, when the output device of the output destination is set to the printer 1, as the output device information of the printer 160-1 corresponding to the printer 1, for example, the pixel pitch is 80 μm, the film size width is 4268 pixels, and the height is Information such as 5108 pixels is acquired.

  Furthermore, the empty area calculation unit 231 acquires image arrangement information such as the image size and arrangement position of the X-ray image currently arranged in the output area from the image arrangement information holding memory 250. Here, for example, one X-ray image has already been arranged, the width of the cut-out size is 2000 pixels, the height is 1400 pixels, and the start point (X, Y) of the arrangement position is the upper left. The information such as (0, 0) is acquired using as the origin.

  In step S201 in FIG. 8, the free area calculation unit 731 determines whether rotation of the output area is valid as a cut-out area calculation condition.

  If the result of determination in step S201 in FIG. 8 is that the rotation of the output area is valid as the cut-out area calculation condition, the process proceeds to step S202 in FIG.

  When the process proceeds to step S202 in FIG. 8, the free area calculation unit 731 determines whether or not an X-ray image already arranged in the output area can be arranged when the output area is rotated.

  As a result of the determination in step S202 in FIG. 8, if the X-ray image already arranged in the output area can be arranged when the output area is rotated, the process proceeds to step S203 in FIG.

  When the processing proceeds to step S203 in FIG. 8, the free area calculation unit 731 determines the output area based on the output device information acquired from the output device information holding memory 240 and the image arrangement information acquired from the image arrangement information holding memory 250. Calculate the free space when rotating and when not rotating.

  In this example, rotation of the output area is effective as a calculation condition, and the arranged X-ray image of 224 mm x 320 mm can be arranged with respect to the vertical 341.11 mm x 408.64 mm of the output area at the time of rotation. The empty area when the output area is rotated and when it is not rotated is calculated. In this case, the empty area at the time of non-rotation is 184.64 mm long × 341.11 mm wide (empty area 1111 in FIG. 11) or 408.64 mm long × 21.11 mm wide (empty area 1112 in FIG. 11). Further, the empty area at the time of rotation is 117.11 mm long × 408.64 mm wide (empty area 1121 in FIG. 11) or 341.11 mm long × 88.64 mm wide (empty area 1122 in FIG. 11).

  Then, when the radiologist (operator) designates the cutout start position 1051 on the cutout region setting screen 1000, in step S204 of FIG. 8, the cutable region calculation unit 732 determines whether the rotation of the cutout image is valid. Judge whether or not.

If the result of determination in step S204 of FIG. 8 is that rotation of the clipped image is valid, the process proceeds to step S205 of FIG.
When the process proceeds to step S205 in FIG. 8, the clippable area calculation unit 732 extracts the clippable area when the clipped image is rotated and when the clipped image is rotated based on the specified clip start position 1051 and the empty area calculated in step S203. Is calculated.

  Here, in this example, since the rotation of the cutout image is valid, if the cutout start position (X, Y) is (0, 400), a total of eight patterns are obtained from the free area calculated in step S203. A cuttable area is calculated.

On the other hand, if the result of the determination in step S204 in FIG. 8 is that the rotation of the clipped image is not valid (invalid), the process proceeds to step S206 in FIG.
When the process proceeds to step S206 in FIG. 8, the cutout area calculation unit 732 calculates a cutout area when the cutout image is not rotated based on the specified cutout start position 1051 and the empty area calculated in step S203. .

  Further, when it is determined in step S201 in FIG. 8 that the rotation of the output area is not valid (invalid), or the X-ray image that has been arranged in the output area in step S202 in FIG. 8 is arranged when the output area is rotated. If it is determined that it is not possible, the process proceeds to step S207 in FIG.

  When the processing proceeds to step S207 in FIG. 8, the free area calculation unit 731 determines the output area based on the output device information acquired from the output device information holding memory 240 and the image arrangement information acquired from the image arrangement information holding memory 250. The free area at the time of non-rotation is calculated.

  Then, when the radiologist (operator) designates the cutout start position 1051 on the cutout area setting screen 1000, subsequently, in step S <b> 208 of FIG. 8, the cutout area calculation unit 732 determines whether the rotation of the cutout image is valid. Judge whether or not.

If the result of determination in step S208 in FIG. 8 is that rotation of the clipped image is valid, the process proceeds to step S209 in FIG.
When the process proceeds to step S209 in FIG. 8, the clippable area calculation unit 732 extracts the clippable area when the clipped image is rotated and when the clipped image is rotated based on the designated clip start position 1051 and the empty area calculated in step S207. Is calculated.

On the other hand, as a result of the determination in step S208 in FIG. 8, if the rotation of the cut-out image is not valid (invalid), the process proceeds to step S210 in FIG.
When the process proceeds to step S210 in FIG. 8, the cutout area calculation unit 732 calculates a cutout area when the cutout image is not rotated based on the specified cutout start position 1051 and the empty area calculated in step S207. .

When the processing in step S205, step S206, step S209, or step S210 in FIG. 8 ends, the process proceeds to step S211 in FIG.
When the process proceeds to step S211 in FIG. 8, the X-ray imaging control unit 115 (for example, the cutout area calculation unit 732) uses the cutout area calculated in step S205, S206, S209, or S210 as the cutout area in FIG. It is displayed on the setting screen 1000. In step S211, along with the X-ray image on the preview image display unit 1050 shown in FIG. 10, based on the setting of the control unit 1064, the croppable region frame related to the croppable region is displayed on the X-ray image and visualized. (Cutable area display step).

  Here, the clippable area when the standard + image rotation is selected by the control unit 1064 in FIG. 10 is reflected in the preview image display unit 450 in FIG. Specifically, the standard frames 1052 and 1053 when the output area is not rotated, and the image rotation frames 1054 and 1055 when the output area is not rotated and the clipped image is rotated are line types designated by the control unit 1064, respectively. Is displayed.

  Further, the uncuttable areas 1056 and 1057 of the preview image display unit 450 in FIG. 10 are displayed by being distinguished (identified) from the cuttable areas by a mask or the like, for example. Note that the method for distinguishing (identifying) and displaying the cuttable area and the noncuttable area is not limited to this mask, and other methods may be used. Then, the operator switches the selection with the control unit 1064, so that the operator can select a frame that the operator wants to see, such as display of all clippable area frames and display of the clippable area frame of rotation of the output area + rotation of the clipped image. It is possible to display.

  Thereafter, when the radiologist (operator) designates the cutout end position with reference to the cutout start position 451 on the cutout area setting screen 1000 shown in FIG. 10 and designates the cutout area, the cutout area input unit 270 Input information about the cut-out area. Specifically, the cutout area input unit 270 inputs information about the cutout area to the image size changing unit 733 and the image arranging unit 734.

  Subsequently, in step S <b> 212 of FIG. 8, for example, the image size changing unit 733 determines that the size of the cutout area from the cutout area input unit 270 is within the cuttable area based on the cutout area calculated by the cutout area calculation unit 732. It is determined whether or not.

  If it is determined in step S212 in FIG. 8 that the size of the clip region input from the clip region input unit 270 is within the clippable range, the process proceeds to step S213 in FIG.

  When the processing proceeds to step S213 in FIG. 3, the image size changing unit 733 uses the size of the cutout area input from the cutout area input unit 270, that is, the size of the cutout area specified by the radiologist (operator). Change the image size of the line image. Here, the information on the set image size is held in the image arrangement information holding memory 250. Then, the X-ray imaging control unit 115 (for example, the cutout control unit 730) shows the cutout frame with the image size changed by the image size changing unit 733, that is, the size of the cutout region designated by the radiologist. It is displayed on the setting screen 1000 for the cutout area. Thereafter, the process proceeds to step S215 in FIG.

  On the other hand, as a result of the determination in step S212 in FIG. 8, if the size of the cutout area input from the cutout area input unit 270 is not within the cuttable range (that is, out of the range), the process proceeds to step S214 in FIG. move on.

  When the process proceeds to step S214 in FIG. 8, the image size changing unit 733 invalidates the cutout area from the cutout area input unit 270, and the maximum size of the cutable area based on the cutout area calculated by the cutout area calculation unit 732 To change the image size. Here, the information on the set image size is held in the image arrangement information holding memory 250. Then, the X-ray image capturing control unit 115 (for example, the clipping control unit 730) sets the clipping frame with the image size changed by the image size changing unit 733, that is, the maximum size of the clipable range shown in FIG. It is displayed on the screen 1000. Thereafter, the process proceeds to step S215 in FIG.

  When the processing proceeds to step S215 in FIG. 8, the image arrangement unit 734 determines whether or not there are a plurality of arrangementable areas of the X-ray image cut out in step S213 or S214.

As a result of the determination in step S215 in FIG. 8, if there are a plurality of X-ray image arrangementable regions cut out in step S213 or S214, the process proceeds to step S216 in FIG.
When the processing proceeds to step S216 in FIG. 8, the image placement unit 734 acquires the priority information of the placement area from the cutout information holding memory 720, and the X-ray cut out in step S213 or S214 in the empty area with high priority. Arrange the images.

On the other hand, as a result of the determination in step S215 in FIG. 8, if there are a plurality of X-ray image arrangementable regions cut out in step S213 or S214 (only one exists), the process proceeds to step S217 in FIG.
When the processing proceeds to step S217 in FIG. 8, the image placement unit 734 places the X-ray image cut out in step S213 or S214 in a free area where the output area can be placed.

  Note that the radiographer (operator) presses the output image button 1080 as appropriate, as in the first embodiment, and the X-ray imaging control unit 115 detects this and operates the output image confirmation screen. -Display on the display unit 116. Then, the radiologist (operator) confirms the output image confirmation screen displayed on the operation / display unit 116.

  Then, when all the X-ray images output by the processing of the cutout control unit 730 are arranged in the output area, the image output unit 280 sets X-ray image data based on the X-ray image to the designated output device. Is output.

  According to the second embodiment, in addition to the effects in the first embodiment, the area that can be cut out when the operator designates the cut-out area is increased, and the free area for the output area can be used effectively. become. In addition, the cost can be reduced when the film is output. Furthermore, since the operator can arbitrarily change the calculation condition of the free area, it is possible to flexibly cope with the requested doctor's preference and the difference in operation such as group examination and normal examination.
