Description

Display method for X-ray imaging device and X-ray imaging device

[0001] The present invention relates to a display method for an X-ray imaging apparatus and an X-ray imaging apparatus.

[0002] BACKGROUND ART Conventionally, an X-ray imaging apparatus including an X-ray source, an X-ray detector, and a display unit has been known. Such an X-ray imaging apparatus is disclosed, for example, in Japanese Patent Application Laid-Open No. 2018-33552.

[0003] JP 2018-33552 A discloses that an X-ray diagnostic apparatus (X-ray imaging apparatus) includes an X-ray tube (X-ray source), an X-ray detector, and a console (display unit) including a display. JP 2018-33552 A discloses that the X-ray detector converts X-ray information transmitted through the subject into image data and transmits the image data to a console in an operation room.

[0004] Furthermore, Japanese Patent Application Laid-Open Publication No. 2018-33552 discloses that the console is a single console that integrates a system for setting and managing imaging conditions and collecting image data with a system for image processing and image display. Japanese Patent Application Laid-Open Publication No. 2018-33552 also discloses that the console displays imaging conditions on a display and accepts settings of imaging conditions from an operator. Japanese Patent Application Laid-Open Publication No. 2018-33552 also discloses that the console collects captured image data, performs preset image processing on the collected image data, changes the image processing through operations using a mouse or keyboard, and displays images on a display.

[0005] JP 2018-33552 A

[0006] Although not explicitly stated in JP 2018-33552 A, in the X-ray diagnostic apparatus of JP 2018-33552 A, the integrated system for setting imaging conditions and the system including the X-ray detector for image processing and image display are believed to be manufactured by the same manufacturer. Furthermore, although not explicitly stated in JP 2018-33552 A, the integration of these systems is believed to also integrate the software used for setting imaging conditions and the software used for image processing and image display. Therefore, in the X-ray diagnostic apparatus of JP 2018-33552 A, it is believed that the screens for image processing and image display, etc., and the screen for setting imaging conditions can be displayed on a single console.

[0007] In contrast, although not disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2018-33552, X-ray detectors manufactured by different manufacturers may be combined and used in an X-ray diagnostic apparatus (X-ray imaging apparatus). That is, in an X-ray imaging apparatus, a system for setting imaging conditions and a system including an X-ray detector for performing image processing and image display, both manufactured by different manufacturers, may be used. In this case, since these systems are not integrated, the software used for setting imaging conditions (imaging condition setting software) and the software used for image processing and image display (X-ray image generation software) are not integrated. Therefore, it is difficult to display screens for image processing and image display, etc., and a screen for setting imaging conditions on a single console. As a result, the screen displayed by the software used for image processing and image display, etc., and the screen displayed by the software used for setting imaging conditions, etc., are displayed on separate display devices. Therefore, it is desirable to realize an environment in which independently provided software for generating X-ray images and software for setting shooting conditions can be executed simultaneously and individually by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device or the manufacturer of the X-ray detector.

[0008] The present invention has been made to solve the above-mentioned problems, and one object of the present invention is to provide a display method for an X-ray imaging device and an X-ray imaging device that can realize an environment in which independently provided X-ray image generation software and imaging condition setting software can be executed simultaneously and individually by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device or the manufacturer of the X-ray detector.

[0009] A display method for an X-ray imaging device in a first aspect of the present invention includes a screen forming step of forming an X-ray image display screen based on the X-ray image generation software and an imaging condition setting screen based on the imaging condition setting software by simultaneously and individually executing, on a single control device, X-ray image generation software, which is a product of a first manufacturer, that generates an X-ray image based on a detection signal output by an X-ray detector and forms an X-ray image display screen, and imaging condition setting software, which is a product of a second manufacturer different from the first manufacturer and is independent of the X-ray image generation software, that sets X-ray image imaging conditions and forms an imaging condition setting screen, and a screen display step of displaying the X-ray image display screen and the imaging condition setting screen side by side in different areas of a display unit.

[0010] An X-ray imaging apparatus in a second aspect of the present invention comprises an X-ray source that irradiates a subject with X-rays, an X-ray detector that detects the X-rays irradiated from the X-ray source, a display unit, X-ray image generating software that is a product of a first manufacturer and generates an X-ray image based on a detection signal output by the X-ray detector and forms an X-ray image display screen, and imaging condition setting software that is a product of a second manufacturer different from the first manufacturer and is independent of the X-ray image generating software and sets imaging conditions for the X-ray image and forms an imaging condition setting screen, by simultaneously and separately executing these software to form an X-ray image display screen based on the X-ray image generating software and an imaging condition setting screen based on the imaging condition setting software, and a single control unit that displays the X-ray image display screen based on the X-ray image generating software and the imaging condition setting screen based on the imaging condition setting software side by side in different areas of the display unit.

[0011] An X-ray imaging apparatus according to a third aspect of the present invention comprises an X-ray source for irradiating a subject with X-rays, an X-ray detector for detecting the X-rays irradiated from the X-ray source, a display unit, an X-ray image display screen based on X-ray image generating software for generating an X-ray image based on a detection signal output by the X-ray detector and forming an X-ray image display screen, and a control unit for displaying the above in different areas of the display unit side by side, wherein the control unit controls the X-ray image display screen so that, when forming the X-ray image display screen using the X-ray image generating software, the total number of pixels constituting the X-ray image display screen is smaller than the total number of pixels constituting the entire display unit, and controls the control unit to display the total number of pixels constituting the imaging condition setting screen is equal to or smaller than the total number of pixels constituting the entire display unit minus the total number of pixels of the X-ray image display screen.

[0012] The display method for an X-ray imaging apparatus according to the first aspect includes a screen forming step of simultaneously and separately executing, in a single control device, X-ray image generating software that is a product of a first manufacturer and imaging condition setting software that is a product of a second manufacturer independent of the X-ray image generating software, thereby forming an X-ray image display screen based on the X-ray image generating software and an imaging condition setting screen based on the imaging condition setting software, and a screen display step of displaying the X-ray image display screen and the imaging condition setting screen side by side in different areas of the display unit. As a result, by simultaneously and separately executing, in a single control device, the X-ray image generating software and the imaging condition setting software that are made by different manufacturers, it is possible to form the X-ray image display screen and the imaging condition setting screen, and to display the X-ray image display screen and the imaging condition setting screen in different areas of the display unit. Therefore, an environment in which the independently provided software for generating X-ray images and software for setting shooting conditions can be executed simultaneously and individually can be realized by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device or the manufacturer of the X-ray detector.

[0013] In the X-ray imaging apparatus according to the second aspect, as described above, the control unit is a single control unit and simultaneously and separately executes the X-ray image generating software, which is a product of a first manufacturer, and the imaging condition setting software, which is a product of a second manufacturer and is independent of the X-ray image generating software, to form an X-ray image display screen based on the X-ray image generating software and an imaging condition setting screen based on the imaging condition setting software, and to display the X-ray image display screen and the imaging condition setting screen side by side in different areas of the display unit. As a result, by simultaneously and separately executing the X-ray image generating software and the imaging condition setting software, which are made by different manufacturers, in a single control unit, it is possible to form the X-ray image display screen and the imaging condition setting screen, and to display the X-ray image display screen and the imaging condition setting screen in different areas of the display unit. Therefore, an environment in which the independently provided software for generating X-ray images and software for setting shooting conditions can be executed simultaneously and individually can be realized by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device or the manufacturer of the X-ray detector.

[0014] In addition, in the X-ray imaging device of the third aspect, as described above, the control unit displays an X-ray image display screen based on the X-ray image generation software and an imaging condition setting screen based on the imaging condition setting software provided independently of the X-ray image generation software side by side in different areas of the display unit, and when forming the X-ray image display screen using the X-ray image generation software, controls the total number of pixels constituting the X-ray image display screen to be smaller than the total number of pixels constituting the entire display unit, and when forming the imaging condition setting screen using the imaging condition setting software, controls the total number of pixels constituting the imaging condition setting screen to be equal to or less than the number of pixels obtained by subtracting the total number of pixels of the X-ray image display screen from the total number of pixels in the entire display unit. By displaying an X-ray image display screen based on the X-ray image generation software and an imaging condition setting screen based on the imaging condition setting software side by side in different areas of the display unit, an environment in which the independently provided X-ray image generation software and imaging condition setting software can be executed simultaneously and individually can be realized by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device or the manufacturer of the X-ray detector. Furthermore, the X-ray image generating software forms an X-ray image display screen so that the total number of pixels constituting the X-ray image display screen is smaller than the total number of pixels constituting the entire display unit of the X-ray imaging device, and the imaging condition setting software forms an imaging condition setting screen so that the total number of pixels constituting the imaging condition setting screen is equal to or less than the total number of pixels constituting the entire display unit minus the total number of pixels of the X-ray image display screen, and by displaying the X-ray image display screen and the imaging condition setting screen side by side in different areas of the display unit, it is possible to display the imaging condition setting screen in an area of ​​a single display unit excluding the area where the X-ray image display screen is displayed, and therefore it is possible to display both the X-ray image display screen based on the X-ray image generating software and the imaging condition setting screen based on the imaging condition setting software on the display unit. Therefore, even if the X-ray image generating software and the imaging condition setting software are not integrated, displaying the X-ray image display screen and the imaging condition setting screen on a single display unit can prevent the configuration of the display unit from becoming complicated and the number of display units from increasing.

[0027] In addition, the control unit 50 controls the display of an X-ray image display screen 71 (see Figure 3) based on the X-ray image generation software 61 and an imaging condition setting screen 72 (see Figure 3) based on the imaging condition setting software 62 side by side in different areas of the display unit 70.

[0028] In addition, the control unit 50 simultaneously and individually executes the X-ray image generation software 61 and the shooting condition setting software 62 to form an X-ray image display screen 71 based on the X-ray image generation software 61 and an shooting condition setting screen 72 based on the shooting condition setting software 62, and controls the display unit 70 to display the X-ray image display screen 71 based on the X-ray image generation software 61 and the shooting condition setting screen 72 based on the shooting condition setting software 62.

[0029] The X-ray image generating software 61 is software for generating an X-ray image based on a detection signal output by the X-ray detector 30. The X-ray image generating software 61 is also software for forming an X-ray image display screen 71 (see FIG. 3) displayed on the display unit 70. The X-ray image generating software 61 is, for example, a product of the first manufacturer.

[0030] The imaging condition setting software 62 is software for setting imaging conditions for X-ray images. The imaging condition setting software 62 forms an imaging condition setting screen 72 (see FIG. 3) displayed on the display unit 70. The imaging condition setting software 62 is provided independently of the X-ray image generating software 61. The imaging condition setting software 62 is, for example, a product of a second manufacturer different from the first manufacturer.

[0031] The storage unit 60 includes a volatile storage device and a nonvolatile storage device, and stores therein software 61 for generating X-ray images, software 62 for setting imaging conditions, a program 63, setting information 64 for X-ray imaging conditions of the X-ray imaging apparatus 100, acquired X-ray image data 65, and coordinate data 66 of the display positions of an X-ray image display screen 71 and an imaging condition setting screen 72 written in a setting file (not shown).

[0032] The input / output unit 41 is composed of various interfaces for inputting and outputting signals to and from the control device 40.

The input unit 42 is, for example, a keyboard and a mouse. The control unit 50 acquires a detection signal (image signal) from the X-ray detector 30 via the input / output unit 41. The control unit 50 also controls the operation of the X-ray irradiation unit 10 to start or stop imaging via the input / output unit 41.

[0033] 3 , as an example, the display unit 70 is configured to include an X-ray image display screen 71 and an imaging condition setting screen 72. On the display unit 70, the X-ray image display screen 71 and the imaging condition setting screen 72 are displayed side by side in different areas of the display unit 70. On the display unit 70, the X-ray image display screen 71 and the imaging condition setting screen 72 are displayed in this order from the left side of the display unit 70 when the user looks at the display unit 70. For ease of explanation, the X-ray image display screen 71 and the imaging condition setting screen 72 are indicated by thick lines.

[0034] The X-ray image display screen 71 includes an X-ray image display area 71a, a subject information display area 71b, a toolbar 71c, and an image processing operation area 71d. The X-ray image display area 71a displays an X-ray image generated by the image generation unit 51 (see FIG. 2 ), which will be described later. The subject information display area 71b displays subject information about the subject 1 from whom the displayed X-ray image was captured. The subject information includes, for example, the subject ID, the subject's date of birth, and the subject's gender. Input operations on the toolbar 71c allow, for example, zooming in and out of the displayed X-ray image. Input operations on the image processing operation area 71d allow, for example, image processing such as gradation processing.

[0035] The imaging condition setting screen 72 displays information on imaging conditions for X-ray imaging that can be set by the imaging condition setting unit 52 (see FIG. 2 ), which will be described later. For example, the imaging condition setting screen 72 displays information 72a on the tube voltage of the X-ray tube (not shown), information 72b on the tube current, information 72c on the X-ray exposure time, and information 72d on the imaging region of the subject 1, which have been set by the user or initially set. Furthermore, on the imaging condition setting screen 72, the imaging condition setting unit 52 is configured to enable the user to change settings such as the tube voltage, tube current, and X-ray exposure time of the X-ray tube, and the imaging region of the subject 1, through input operations.

[0036] (Processing of Control Unit) The processing executed by the control unit 50 will be described with reference to FIG. 2 . The control unit 50, which is composed of hardware such as a CPU, includes an image generation unit 51, an imaging condition setting unit 52, an imaging control unit 53, and a display control unit 54 as functional blocks of software (application software) and a program 63. The control unit 50 functions as the image generation unit 51 by executing the X-ray image generation software 61 stored in the storage unit 60. The control unit 50 also functions as the imaging condition setting unit 52 by executing the imaging condition setting software 62 stored in the storage unit 60. The control unit 50 also functions as the display control unit 54 and the imaging control unit 53 by executing the program 63 stored in the storage unit 60.

The image generation unit 51 is also configured to form an X-ray image display screen 71 (see FIG. 3). The image generation unit 51 is also configured to display the generated X-ray image on the X-ray image display screen 71. The image generation unit 51 is also configured to perform image processing such as gradation processing on the X-ray image displayed on the X-ray image display screen 71 based on a user's input instruction for an operation image.

[0038] The image generation unit 51 is configured to control, when the X-ray image generation software 61 is executed to form an X-ray image display screen 71 (see FIG. 3 ), the total number of pixels constituting the X-ray image display screen 71 to be smaller than the total number of pixels constituting the entire display unit 70. In detail, when the X-ray image generation software 61 is executed to form the X-ray image display screen 71, the image generation unit 51 is configured to control, when the X-ray image generation software 61 is executed to form the X-ray image display screen 71, the total number of pixels on the X-ray image display screen 71 to be a total number of pixels selected in advance from a plurality of total numbers of pixels set in advance so that the X-ray image display screen 71 can be displayed.

[0039] Here, the commonly used X-ray image generating software 61 is configured to be capable of displaying in accordance with a plurality of total pixel counts in order to perform full-screen display on each of a plurality of display units 70 having different total pixel counts. That is, the X-ray image generating software 61 is configured to be capable of full-screen display of the X-ray image display screen 71 on a display unit 70 having a total pixel count of 1920 horizontal pixels by 1080 vertical pixels, a display unit 70 having a total pixel count of 1280 horizontal pixels by 1024 vertical pixels, a display unit 70 having a total pixel count of 1600 horizontal pixels by 1200 vertical pixels, or a display unit 70 having a total pixel count of 800 horizontal pixels by 600 vertical pixels. The X-ray image generation software 61 is configured to display the X-ray image display screen 71 with an appropriate total number of pixels for full-screen display corresponding to the display unit 70 given as an example above, and when the display unit 70 is changed to one with a different total number of pixels, to switch to an appropriate total number of pixels for full-screen display corresponding to the changed display unit 70 and display the X-ray image display screen 71.

[0040] In the present invention, while using the above-described X-ray image generating software 61, the image generating unit 51 does not form the X-ray image display screen 71 in full screen display on the display unit 70, but forms the X-ray image display screen 71 on the display unit 70 with a number of pixels smaller than the total number of pixels constituting the entire display unit 70. At this time, the total number of pixels of the formed X-ray image display screen 71 is a total number of pixels selected in advance from a plurality of types of total numbers of pixels that are set in advance so that the X-ray image display screen 71 can be displayed.

[0041] 3 , the X-ray image generation software 61 is configured to be able to display an X-ray image display screen 71 full screen on a display unit 70 having a total pixel count of 1920 horizontal pixels and 1080 vertical pixels, a display unit 70 having a total pixel count of 1280 horizontal pixels and 1024 vertical pixels, a display unit 70 having a total pixel count of 1600 horizontal pixels and 1200 vertical pixels, or a display unit 70 having a total pixel count of 800 horizontal pixels and 600 vertical pixels, etc. If the display unit 70 has a total pixel count of 1920 horizontal pixels and 1080 vertical pixels, the image generation unit 51 forms the X-ray image display screen 71 on the display unit 70 with a total pixel count of 1280 horizontal pixels and 1024 vertical pixels that is preselected from a plurality of preset total pixel counts. In this embodiment, the total pixel count of the X-ray image display screen 71 formed on the display unit 70 is selected when the X-ray imaging apparatus 100 is installed.

[0042] 2, the imaging condition setting unit 52 is configured to form an imaging condition setting screen 72 (see FIG. 3). The imaging condition setting unit 52 is also configured to set, based on an instruction input by a user, the tube voltage, tube current, and X-ray exposure time of an X-ray tube (not shown), an imaging region of the subject 1, and the like. The imaging condition setting unit 52 is also configured to display, on the imaging condition setting screen 72, information 72a of the tube voltage of the X-ray tube, information 72b of the tube current, information 72c of the X-ray exposure time, and information 72d of the imaging region of the subject 1, which are set by the user or initially set.

[0043] The imaging condition setting unit 52 is configured to control, when the imaging condition setting software 62 is executed to form the imaging condition setting screen 72, the total number of pixels constituting the imaging condition setting screen 72 to be equal to or less than the number of pixels obtained by subtracting the total number of pixels of the X-ray image display screen 71 from the total number of pixels of the entire display unit 70. In detail, when the imaging condition setting software 62 is executed to form the imaging condition setting screen 72, the imaging condition setting unit 52 is configured to control, when the imaging condition setting software 62 is executed to form the imaging condition setting screen 72, the total number of pixels of the imaging condition setting screen 72 to be a total number of pixels selected in advance from a plurality of types of total numbers of pixels set in advance so that the imaging condition setting screen 72 can be displayed in an area of ​​the display unit 70 where the X-ray image display screen 71 is not displayed.

[0044] Here, the imaging condition setting software 62 is configured to be able to form the imaging condition setting screen 72 with a plurality of different total pixel numbers so as to correspond to each of a plurality of X-ray image display screens 71 with different total pixel numbers formed on a plurality of display units 70. The imaging condition setting unit 52 forms the imaging condition setting screen 72 on the display unit 70 with a pixel number equal to or less than the total pixel number of the entire display unit 70 minus the total pixel number of the X-ray image display screen 71. At this time, the total pixel number of the formed imaging condition setting screen 72 is a total pixel number selected in advance from a plurality of different total pixel numbers set in advance so that the imaging condition setting screen 72 can be displayed in an area where the X-ray image display screen 71 is not displayed.

[0045] 3 , if the display unit 70 has a total pixel count of 1920 horizontal pixels×1080 vertical pixels, and the image generation unit 51 forms the X-ray image display screen 71 with a preselected total pixel count of 1280 horizontal pixels×1024 vertical pixels, the imaging condition setting unit 52 forms the imaging condition setting screen 72 on the display unit 70 with a total pixel count of 640 horizontal pixels×1024 vertical pixels selected in advance from among a plurality of total pixel counts set in advance. In this embodiment, the total pixel count of the imaging condition setting screen 72 formed on the display unit 70 is selected when the X-ray imaging apparatus 100 is installed.

[0046] As shown in FIG. 2, the imaging control unit 53 controls the X-ray source 11 to emit X-rays and to stop the emission based on the imaging conditions set by the imaging condition setting unit 52 .

[0047] The display control unit 54 is configured to display an X-ray image display screen 71 based on the X-ray image generation software 61 and an imaging condition setting screen 72 based on the imaging condition setting software 62 side by side in different areas of the display unit 70.

[0048] The display control unit 54 is configured to display the X-ray image display screen 71 formed by the image generation unit 51 at a fixed position and size on the display unit 70 so that it cannot be enlarged or reduced. The display control unit 54 is also configured to display the imaging condition setting screen 72 formed by the imaging condition setting unit 52 at a fixed position and size on the display unit 70 so that it cannot be enlarged or reduced.

[0049] 3, the display control unit 54 is configured to display an X-ray image display screen 71 at a fixed position and size on the left side of the display unit 70, with a total number of horizontal pixels of 1280×vertical pixels of 1024, and unable to be enlarged or reduced. The display control unit 54 is also configured to display an imaging condition setting screen 72 at a fixed position and size on the right side of the display unit 70, with a total number of horizontal pixels of 640×vertical pixels of 1024, and unable to be enlarged or reduced.

[0050] That is, the display control unit 54 is configured to prohibit the user from changing the display size or position of the X-ray image display screen 71 and the imaging condition setting screen 72, or from displaying only one of the screens, while the control device 40 is running. As a result, the X-ray imaging device 100 is configured so that the X-ray image display screen 71 and the imaging condition setting screen 72 are automatically displayed on the display unit 70 at a fixed position and size and unable to be enlarged or reduced, from the time the control device 40 is powered on until the control device 40 is powered off.

[0051] Moreover, as an example, the display control unit 54 is configured to display the X-ray image display screen 71 and the imaging condition setting screen 72 side by side in the left-right direction of the display unit 70. The display control unit 54 displays the X-ray image display screen 71 and the imaging condition setting screen 72 in order from the left side of the display unit 70 when the user looks at the display unit 70, so that they do not overlap.

[0052] As an example, the display control unit 54 controls the position of one left-right end 71e of the X-ray image display screen 71 so that it is located at one left-right end 70a of the display unit 70, and controls the position of the other left-right end 71f of the X-ray image display screen 71 so that it is located at a position based on the total number of pixels of the X-ray image display screen 71 that has been selected in advance.

[0053] In the present embodiment, the display control unit 54 controls the position of the left end in the horizontal direction of the X-ray image display screen 71 (one end 71e in the horizontal direction of the X-ray image display screen 71) so that it is located at the left end in the horizontal direction of the display unit 70 (one end 70a in the horizontal direction of the display unit 70), and sets the position of the right end in the horizontal direction of the X-ray image display screen 71 (the other end 71f in the horizontal direction of the X-ray image display screen 71) to a position based on a preselected total number of pixels of the X-ray image display screen 71. That is, for example, when the display unit 70 has a total number of pixels of 1920 X coordinates and 1080 Y coordinates, and the X-ray image display screen 71 is formed by a total number of pixels of 1280 horizontal pixels and 1024 vertical pixels, the display control unit 54 is configured to display the X-ray image display screen 71 within the X coordinate range of 0 to 1280.

[0054] As an example, the display control unit 54 controls the position of one left-right end 72e of the shooting condition setting screen 72 so that it is located at the other left-right end 70b of the display unit 70, and controls the position of the other left-right end 72f of the shooting condition setting screen 72 so that it is located at a position based on the total number of pixels of the shooting condition setting screen 72 that has been selected in advance.

[0055] In the present embodiment, the display control unit 54 controls the position of the right end in the horizontal direction of the imaging condition setting screen 72 (one end 72 e in the horizontal direction of the imaging condition setting screen 72) to be located at the right end in the horizontal direction of the display unit 70 (the other end 70 b in the horizontal direction of the display unit 70), and controls the position of the left end in the horizontal direction of the imaging condition setting screen 72 (the other end 72 f in the horizontal direction of the imaging condition setting screen 72) to be located at a position based on the pre-selected total number of pixels of the imaging condition setting screen 72. That is, for example, in a case where the display unit 70 has a total number of pixels of 1920 in the X coordinate and 1080 in the Y coordinate, the X-ray image display screen 71 is formed by a total number of pixels of 1280 in the horizontal direction and 1024 in the vertical direction, and the imaging condition setting screen 72 is formed by a total number of pixels of 640 in the horizontal direction and 1024 in the vertical direction, the display control unit 54 is configured to display the imaging condition setting screen 72 within the X coordinate range of 1281 to 1920.

[0056] In this embodiment, when the X-ray imaging apparatus 100 is installed, the display position coordinate data 66 is written and saved in the setting file so that the screen position of the X-ray image display screen 71 has an X coordinate in the range of 0 to 1280. Also, when the X-ray imaging apparatus 100 is installed, the display position coordinate data 66 is written and saved in the setting file so that the screen position of the imaging condition setting screen 72 has an X coordinate in the range of 1281 to 1920. Similarly, when the X-ray imaging apparatus 100 is installed, the display position coordinate data 66 is written and saved in the setting file so that the screen positions of the X-ray image display screen 71 and the imaging condition setting screen 72 have a Y coordinate in the range of 29 to 1052. That is, the display position coordinate data 66 is written in the setting file so that the screen positions of the X-ray image display screen 71 and the imaging condition setting screen 72 have an extra 28 pixels at each of the top and bottom edges of the display unit 70. When the X-ray image generation software 61 and the shooting condition setting software 62 are started (executed), the display control unit 54 reads the setting file and displays the X-ray image display screen 71 and the shooting condition setting screen 72 based on the coordinate data 66 of the display position.

[0057] (Display Processing of X-Ray Image Display Screen and Imaging Condition Setting Screen) A series of display processing flows for the X-ray image display screen 71 and the imaging condition setting screen 72 according to one embodiment of the present invention will be described with reference to FIG.

[0058] In step S1, the display control unit 54 reads the setting file when the X-ray image generation software 61 and the imaging condition setting software 62 are started (executed), thereby acquiring coordinate data 66 of the display positions of the set X-ray image display screen 71 and imaging condition setting screen 72. Thereafter, the process proceeds to step S2.

[0059] In step S2, the image generating unit 51 generates an X-ray image display screen 71 using the X-ray image generating software 61. Thereafter, the process proceeds to step S3.

[0060] In step S3, the imaging condition setting unit 52 forms an imaging condition setting screen 72 using the imaging condition setting software 62. Thereafter, the process proceeds to step S4. Note that the order of steps S1, S2, and S3 may be any order, or they may be performed simultaneously.

[0061] In step S4, the display control unit 54 displays the X-ray image display screen 71 and the imaging condition setting screen 72 on the display unit 70. Thereafter, the process ends.

[0062] (Effects of this embodiment) In this embodiment, the following effects can be obtained.

[0063] In this embodiment, as described above, the display method in the X-ray imaging device 100 includes a screen formation step of forming the X-ray image display screen 71 based on the X-ray image generation software 61 and the imaging condition setting screen 72 based on the imaging condition setting software 62 by simultaneously and individually executing, on a single control device 40, the X-ray image generation software 61, which is a product of a first manufacturer, and which generates an X-ray image based on a detection signal output by the X-ray detector 30 and forms an X-ray image display screen 71, and the imaging condition setting software 62, which is a product of a second manufacturer different from the first manufacturer and is independent of the X-ray image generation software 61, and which sets X-ray image imaging conditions and forms an imaging condition setting screen 72; and a screen display step of displaying the X-ray image display screen 71 and the imaging condition setting screen 72 side by side in different areas of the display unit 70. As a result, the X-ray image generating software 61 and the imaging condition setting software 62, which are made by different manufacturers, can be simultaneously and individually executed in one control device 40, thereby forming an X-ray image display screen 71 and an imaging condition setting screen 72, and displaying the X-ray image display screen 71 and the imaging condition setting screen 72 in different areas of the display unit 70. Therefore, an environment in which the independently provided X-ray image generating software 61 and the imaging condition setting software 62 can be simultaneously and individually executed can be realized by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device 100 and the manufacturer of the X-ray detector 30.

[0064] Furthermore, in the above embodiment, the following additional effects can be obtained by configuring as follows.

[0065] That is, in this embodiment, as described above, the screen formation step forms the X-ray image display screen 71 by the X-ray image generating software 61 so that the total number of pixels constituting the X-ray image display screen 71 is smaller than the total number of pixels constituting the entire display unit 70, and forms the imaging condition setting screen 72 by the imaging condition setting software 62 so that the total number of pixels constituting the imaging condition setting screen 72 is equal to or smaller than the number of pixels obtained by subtracting the total number of pixels of the X-ray image display screen 71 from the total number of pixels of the entire display unit 70. This makes it possible to display the imaging condition setting screen 72 in an area of ​​one display unit 70 excluding the area where the X-ray image display screen 71 is displayed, and therefore it is possible to display both the X-ray image display screen 71 based on the X-ray image generating software 61 and the imaging condition setting screen 72 based on the imaging condition setting software 62 on the display unit 70. Therefore, when the software 61 for generating X-ray images and the software 62 for setting shooting conditions are not integrated, by displaying the X-ray image display screen 71 and the shooting condition setting screen 72 on a single display unit 70, it is possible to prevent the configuration of the display unit 70 from becoming complicated and the number of display units 70 from increasing.

[0066] Furthermore, in this embodiment, as described above, the screen forming step involves forming the X-ray image display screen 71 by the X-ray image generating software 61 so that the total number of pixels of the X-ray image display screen 71 is a total number of pixels preselected from among multiple total numbers of pixels preselected so that the X-ray image display screen 71 can be displayed, and forming the imaging condition setting screen 72 by the imaging condition setting software 62 so that the total number of pixels of the imaging condition setting screen 72 is a total number of pixels preselected from among multiple total numbers of pixels preselected so that the imaging condition setting screen 72 can be displayed in an area of ​​the display unit 70 where the X-ray image display screen 71 is not displayed. By selecting the total number of pixels of the X-ray image display screen 71 from among multiple total numbers of pixels preselected so that the X-ray image display screen 71 can be displayed, the imaging condition setting screen 72 can be formed using the existing X-ray image generating software 61 as is. Furthermore, the total number of pixels of the imaging condition setting screen 72 can be selected from multiple total numbers of pixels based on the selected total number of pixels of the X-ray image display screen 71. For these reasons, when the X-ray image generation software 61 and the shooting condition setting software 62 are not integrated, the X-ray image display screen 71 and the shooting condition setting screen 72 can be easily displayed on a single display unit 70.

[0067] Furthermore, in this embodiment, as described above, the screen display step displays the X-ray image display screen 71 formed by the X-ray image generation software 61 on the display unit 70 at a fixed position and size so that it cannot be enlarged or reduced, and displays the imaging condition setting screen 72 formed by the imaging condition setting software 62 on the display unit 70 at a fixed position and size so that it cannot be enlarged or reduced. Here, the X-ray image display screen 71 and the imaging condition setting screen 72 are screens on which information necessary for X-ray imaging is displayed, and therefore they need to be displayed on the display unit 70 during X-ray imaging. By displaying the X-ray image display screen 71 and the imaging condition setting screen 72 on the display unit 70 at a fixed position and size so that it cannot be enlarged or reduced, it is possible to prevent the X-ray image display screen 71 and the imaging condition setting screen 72 from being partially or entirely hidden from view due to a change in the display position or display size of the screen during X-ray imaging.

[0068] Furthermore, in this embodiment, as described above, the screen display step displays the X-ray image display screen 71 and the shooting condition setting screen 72 side by side in the left-right direction of the display unit 70, displays one left-right end of the X-ray image display screen 71 formed by the X-ray image generation software 61 so as to be located at one left-right end of the display unit 70, and displays the other left-right end of the X-ray image display screen 71 so as to be located at a position based on the pre-selected total number of pixels of the X-ray image display screen 71, displays one left-right end of the shooting condition setting screen 72 formed by the shooting condition setting software 62 so as to be located at the other left-right end of the display unit 70, and displays the other left-right end of the shooting condition setting screen 72 so as to be located at a position based on the pre-selected total number of pixels of the shooting condition setting screen 72. This makes it possible to easily display the X-ray image display screen 71 and the shooting condition setting screen 72 on a single display unit 70 when the X-ray image generation software 61 and the shooting condition setting software 62 are not integrated.

[0069] In this embodiment, as described above, the displayed imaging condition setting screen 72 is configured to allow the user to set at least the tube voltage, tube current, and X-ray exposure time. This allows the user to easily set the tube voltage, tube current, and X-ray exposure time of the X-ray tube (not shown) on the imaging condition setting screen 72 displayed on the display unit 70, and also allows the user to easily visually confirm the tube voltage, tube current, and X-ray exposure time of the X-ray tube (not shown).

In this way, by simultaneously and individually executing the X-ray image generating software 61 and the imaging condition setting software 62, which are products of different manufacturers, in a single control unit 40, it is possible to form the X-ray image display screen 71 and the imaging condition setting screen 72, and display the X-ray image display screen 71 and the imaging condition setting screen 72 in different areas of the display unit 70. Therefore, an environment in which the independently provided X-ray image generation software 61 and shooting condition setting software 62 can be executed simultaneously and individually can be realized by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device 100 and the manufacturer of the X-ray detector 30.

[0071] Furthermore, in the above embodiment, the following additional effects can be obtained by configuring as follows.

[0072] That is, in this embodiment, as described above, when the X-ray image display screen 71 is formed by the X-ray image generating software 61, the control unit 50 controls the total number of pixels constituting the X-ray image display screen 71 to be smaller than the total number of pixels constituting the entire display unit 70, and when the imaging condition setting screen 72 is formed by the imaging condition setting software 62, the control unit 50 controls the total number of pixels constituting the imaging condition setting screen 72 to be equal to or smaller than the number of pixels obtained by subtracting the total number of pixels of the X-ray image display screen 71 from the total number of pixels of the entire display unit 70. This makes it possible to display the imaging condition setting screen 72 in an area of ​​one display unit 70 excluding the area where the X-ray image display screen 71 is displayed, and therefore it is possible to display both the X-ray image display screen 71 based on the X-ray image generating software 61 and the imaging condition setting screen 72 based on the imaging condition setting software 62 on the display unit 70. Therefore, when the software 61 for generating X-ray images and the software 62 for setting shooting conditions are not integrated, by displaying the X-ray image display screen 71 and the shooting condition setting screen 72 on a single display unit 70, it is possible to prevent the configuration of the display unit 70 from becoming complicated and the number of display units 70 from increasing.

[0073] In addition, in this embodiment, as described above, the X-ray imaging apparatus 100 includes the X-ray source 11 that irradiates the subject with X-rays, the X-ray detector 30 that detects the X-rays irradiated from the X-ray source 11, the display unit 70, the X-ray image display screen 71 based on the X-ray image generating software 61 that generates an X-ray image based on a detection signal output by the X-ray detector 30 and forms the X-ray image display screen 71, and the imaging condition setting screen 72 based on the imaging condition setting software 62 that is provided independently of the X-ray image generating software 61 and sets imaging conditions for the X-ray image and forms the imaging condition setting screen 72. and a control unit (50) that displays the X-ray image display screen (72) side by side in different areas of the display unit (70). When the X-ray image generation software (61) forms the X-ray image display screen (71), the control unit (50) controls the total number of pixels that make up the X-ray image display screen (71) to be smaller than the total number of pixels that make up the entire display unit (70), and when the imaging condition setting software (62) forms the imaging condition setting screen (72), the control unit (50) controls the total number of pixels that make up the imaging condition setting screen (72) to be equal to or less than the number of pixels obtained by subtracting the total number of pixels of the X-ray image display screen (71) from the total number of pixels of the entire display unit (70). By displaying an X-ray image display screen 71 based on the X-ray image generation software 61 and an imaging condition setting screen 72 based on the imaging condition setting software 62 side by side in different areas of the display unit 70, an environment in which the independently provided X-ray image generation software 61 and imaging condition setting software 62 can be executed simultaneously and individually can be realized by flexibly combining them without being restricted by the manufacturer of the X-ray imaging device 100 and the manufacturer of the X-ray detector 30.Furthermore, the X-ray image generation software 61 forms the X-ray image display screen 71 so that the total number of pixels constituting the X-ray image display screen 71 is smaller than the total number of pixels constituting the entire display unit 70 of the X-ray imaging device 100, and the imaging condition setting software 62 forms the imaging condition setting screen 72 so that the total number of pixels constituting the imaging condition setting screen 72 is equal to or less than the total number of pixels constituting the entire display unit 70 minus the total number of pixels of the X-ray image display screen 71. By displaying the X-ray image display screen 71 and the imaging condition setting screen 72 side by side in different areas of the display unit 70, it is possible to display the imaging condition setting screen 72 in an area of ​​one display unit 70 excluding the area where the X-ray image display screen 71 is displayed. Therefore, it is possible to display both the X-ray image display screen 71 based on the X-ray image generation software 61 and the imaging condition setting screen 72 based on the imaging condition setting software 62 on the display unit 70. Therefore, when the software 61 for generating X-ray images and the software 62 for setting shooting conditions are not integrated, by displaying the X-ray image display screen 71 and the shooting condition setting screen 72 on a single display unit 70, it is possible to prevent the configuration of the display unit 70 from becoming complicated and the number of display units 70 from increasing.
