[0006] Patent Document 1: Japanese Patent No. 5510540 Summary of the invention

[0007] Problem that the invention aims to solve

[0008] Here, the position of the display panel is not clearly stated in the above-mentioned Japanese Patent No. 5510540 Gazette, but generally speaking, the display panel is arranged at a position away from the operating panel on the upper side of the subject. When such a structure is applied to the above-mentioned Japanese Patent No. 5510540 Gazette, when moving the two arms, the operator needs to move his sight to the display panel while confirming the operating panel at hand, so improvement is desired. In addition, although it is not clearly stated in the above-mentioned Japanese Patent No. 5510540 Gazette, generally speaking, the target imaging angle is only displayed numerically in the display panel. When such a structure is applied to the above-mentioned Japanese Patent No. 5510540 Gazette, the operator needs to grasp the position of the two arms (X-ray source) relative to the subject based on the numerical value representing the target imaging angle. In this case, the X-ray imaging device of the above-mentioned Japanese Patent No. 5510540 Gazette cannot intuitively perform the operation for moving the X-ray source, so improvement is desired.

[0009] The present invention is made to solve the above-mentioned problems, and one object of the present invention is to provide an X-ray imaging device that can perform operations for moving an X-ray source without moving the line of sight and can perform operations for moving the X-ray source intuitively.

[0010] Solutions for solving problems

[0011] In order to achieve the above-mentioned purpose, an X-ray imaging device according to one aspect of the present invention comprises: a first arm, which supports a first X-ray source and a first X-ray detector in a manner facing each other; a second arm, which supports a second X-ray source and a second X-ray detector in a manner facing each other; an imaging angle setting unit, which sets a target imaging angle of each of the first X-ray source and the second X-ray source; and a display unit, which displays the content set by the imaging angle setting unit, wherein the display unit is configured to display a configuration screen, the configuration screen shows a configuration corresponding to the positions of the first X-ray source and the second X-ray source at a target imaging angle relative to an actual position of a subject, and the imaging angle setting unit and the display unit are arranged in the same configuration area of ​​the X-ray imaging device body.

[0012] Effects of the Invention

[0013] In the X-ray imaging device of one aspect described above, the display unit is configured to display a configuration screen, which shows a configuration corresponding to the positions of the first X-ray source and the second X-ray source at a target imaging angle relative to the actual position of the subject. Thus, according to the configuration screen, the positions of the first X-ray source and the second X-ray source relative to the subject can be understood through an image that can be visually confirmed like a map. In addition, the imaging angle setting unit and the display unit are arranged in the same configuration area of ​​the main body of the X-ray imaging device. Thus, the imaging angle setting unit and the display unit can be confirmed without moving the line of sight. As a result of the above, the operation for moving the first X-ray source and the second X-ray source can be performed without moving the line of sight, and the operation for moving the first X-ray source and the second X-ray source can be performed intuitively.

That is, the display unit 3 and the imaging angle setting unit 4 are provided in the same configuration area 103 of the X-ray imaging device body 100a. Therefore, the operator can visually confirm the imaging angle setting unit 4 to perform an operation while visually confirming the display unit 3 at the same time. Therefore, the operator does not need to move his / her sight when visually confirming both the imaging angle setting unit 4 and the display unit 3.

[0030] (Structure of First X-ray Source, First X-ray Detector, and First Arm)

[0031] The first X-ray source 1a is an X-ray irradiation unit composed of an X-ray tube that irradiates X-rays by applying a voltage.

The first X-ray source 1a irradiates X-rays toward the subject 101 mainly from the body axis direction side and the up-down direction side of the subject 101.

[0032] The first X-ray detector 1b detects X-rays that have passed through the subject 101. And the first X-ray detector 1b outputs a detection signal based on the detected X-rays. As an example, the first X-ray detector 1b is composed of an FPD (Flat Panel Detector). In addition, as an example, the first X-ray detector 1b is configured as a wireless X-ray detector, and outputs the detection signal as a wireless signal to an X-ray image generation unit (not shown) via a wireless LAN or the like. The X-ray image generation unit generates an X-ray image based on the detection signal. The generated X-ray image is output to a display device (not shown) in a manner that can be confirmed by an operator.

[0033] The first arm 1, which is configured as a so-called forearm, is provided with a base portion 10a disposed on the ground and a support portion 10b mounted on the base portion 10a. The first arm 1 is supported by the support portion 10b and is placed on the ground via the base portion 10a.

[0034] The first arm 1 includes a C-shaped arm portion 11 that is arc-shaped (C-shaped) when viewed from the left-right direction (Y direction), and an arm holder portion 12 that supports the C-shaped arm portion 11 so as to be movable in the arc direction. The first X-ray source 1a is supported at one end of the C-shaped arm portion 11, and the first X-ray detector 1b is supported at the other end, so that the first X-ray source 1a and the first X-ray detector 1b face each other with the subject 101 interposed therebetween.

[0035] The first arm 1 is provided with a rotation mechanism 13 and a drive motor 14a for rotating the C-shaped arm portion 11 in an arc direction around a left-right axis (an axis orthogonal to the body axis in a horizontal plane) relative to the arm holder portion 12, and a rotary encoder 14b for detecting the rotation angle of the drive motor 14a. The detection value of the rotary encoder 14b is output to the CPU 200.

[0036] The rotating mechanism 13 is accommodated in the arm holder portion 12. The rotating mechanism 13 includes: a belt 13a mounted on the C-shaped arm portion 11; a driving roller 13b around which the belt 13a is wound and to which a torque is applied by a driving motor 14a; and a guide roller 13c that guides the belt 13a toward the driving roller 13b.

[0037] In addition, the first arm 1 is provided with a drive motor 15a for rotating the arm holder portion 12 relative to the support portion 10b around the body axis, and a rotary encoder 15b for detecting the rotation angle of the drive motor 15a. The drive motor 15a rotates the arm holder portion 12 via a pinion 16a and a gear 16b that rotates together with the pinion 16a. The detection value of the rotary encoder 15b is output to the CPU 200.

[0038] The first arm 1 is colored in a first exterior color 6a (in Figure 1 As a specific example, the inner surface of the first arm 1 is colored with blue, which is the first appearance color 6a. In addition, the first X-ray source 1a and the first X-ray detector 1b are also colored with blue, which is the first appearance color 6a, similarly to the first arm 1. Figure 1 , and in other figures, Figure 1 Similarly, the color of the portion indicated by the wide hatching is the same as the first apparent color 6 a .

[0039] (Structure of Second X-ray Source, Second X-ray Detector and Second Arm)

[0040] The second X-ray source 2a and the second X-ray detector 2b have the same configuration as the first X-ray source 1a and the first X-ray detector 1b described above, and thus description thereof is omitted. The second X-ray source 2a is mainly arranged on the left side of the supine subject 101 .

[0041] The second arm 2, which is a so-called lateral arm, is provided with a base 20a disposed on the top surface. The second arm 2 is supported by the base 20a. The base 20a is supported by a guide rail 20b extending in the body axis direction and the left-right direction and is movable in the horizontal direction together with the second arm 2.

[0042] The second arm 2 includes a C-shaped arm portion 21 that is arc-shaped (C-shaped) when viewed from the body axis direction, and an arm holder portion 22 that supports the C-shaped arm portion 21 so as to be movable in the arc direction. The second X-ray source 2a is supported at one end of the C-shaped arm portion 21, and the second X-ray detector 2b is supported at the other end, so that the second X-ray source 2a and the second X-ray detector 2b face each other with the subject 101 interposed therebetween.

[0043] The second arm 2 is provided with a rotation mechanism 23 and a drive motor 24a for rotating the C-arm portion 21 in an arc direction around the body axis relative to the arm holder portion 22, and a rotary encoder 24b for detecting the rotation angle of the drive motor 24a. The detection value of the rotary encoder 24b is output to the CPU 200.

[0044] The rotating mechanism 23 is accommodated in the arm holder portion 22. The rotating mechanism 23 includes a belt 23a mounted on the C-shaped arm portion 21, a driving roller 23b around which the belt 23a is wound and to which a torque is applied by a driving motor 24a, and a guide roller 23c that guides the belt 23a toward the driving roller 23b.

[0045] The second arm 2 is provided with a rotation mechanism (not shown) for rotating the arm holder 22 about the vertical axis relative to the base 20a, a drive motor 25a, and a rotary encoder 25b for detecting the rotation angle of the drive motor 25a. The detection value of the rotary encoder 25b is output to the CPU 200.

[0046] The second arm 2 is colored in a second apparent color 6b (in Figure 1 As a specific example, the inner surface of the second arm 2 is colored with yellow as the second appearance color 6b. In addition, the second X-ray source 2a and the second X-ray detector 2b are also colored with yellow as the second appearance color 6b like the second arm 2. Figure 1 , and in other figures, Figure 1Similarly, the color of the portion indicated by the narrow hatching is the same as the second apparent color 6 b .

[0047] (CPU structure)

[0048] The CPU 200 is configured to drive the first arm 1 so that the first X-ray source 1a is arranged at the target imaging angle by acquiring the detection values ​​of the rotary encoders 14b, 15b, etc. and controlling the driving of the drive motors 14a, 15a, etc. based on the target imaging angle signal output from the touch panel 300 (control unit 5). In addition, the CPU 200 is configured to drive the second arm 2 so that the second X-ray source 2a is arranged at the target imaging angle by acquiring the detection values ​​of the rotary encoders 24b, 25b, etc. and controlling the driving of the drive motors 24a, 25a, etc. based on the target imaging angle signal output from the touch panel 300 (control unit 5).

[0049] (Structure of Display Section and Shooting Angle Setting Section)

[0050] The display unit 3 is composed of a display capable of touch operation. As an example, the display unit 3 is a liquid crystal display. The display unit 3 is configured to display the content set by the imaging angle setting unit 4. The imaging angle setting unit 4 is an operation unit for setting the target imaging angles of the first X-ray source 1a and the second X-ray source 2a. Specifically, the imaging angle setting unit 4 is various operation switches on the display unit 3 (touch panel 300) for setting the target imaging angles of the first X-ray source 1a and the second X-ray source 2a.

[0051] The display unit 3 is configured to display a screen for accepting input operations of the operator to the X-ray imaging device 100. In detail, the display unit 3 is configured to be able to display two images, namely, a pre-configuration setting screen (direct memory setting screen) 7 and a configuration screen 8 based on information set in the pre-configuration setting screen 7. The configuration screen 8 is an operation setting screen for arranging the first X-ray source 1a and the second X-ray source 2a at a predetermined position during actual imaging. The pre-configuration setting screen 7 is an operation setting screen (a screen for direct memory) for storing information required for displaying the configuration screen 8 on the display unit 3 in advance in the storage unit 5a.

[0052] (About the pre-configuration settings screen)

[0053] The pre-configuration setting screen 7 is a screen for setting the configurations of the first X-ray source 1a and the second X-ray source 2a to be associated with each other, and setting the target imaging angles of the first X-ray source 1a and the second X-ray source 2a. The X-ray source configuration information for associating the configurations of the first X-ray source 1a and the second X-ray source 2a is stored in the storage unit 5a.

[0054] As an example, as content displayed on the pre-configuration setting screen 7, the current imaging angle of the first X-ray source 1a and the second X-ray source 2a, and the current configuration of the first X-ray source 1a and the second X-ray source 2a relative to the subject 101 when viewed from above are displayed on the upper side of the screen as current imaging angle information.

[0055] In addition, Figure 5 In the current imaging angle information shown in the pre-configuration setting screen 7, among the 3×3 cells, since the cell at the lower left of the screen is displayed in the same blue as the first appearance color 6a, it can be understood that the first X-ray source 1a is arranged on the right side and the head side of the subject 101. In addition, since the cell at the upper right of the screen is displayed in the same yellow as the second appearance color 6b, it can be understood that the second X-ray source 2a is arranged on the left side and the lower limb side of the subject 101.

[0056] In addition, as content displayed on the pre-configuration setting screen 7, 3×3 (a total of nine) imaging angle setting switches 70 are displayed on the lower side of the screen as setting information for the target imaging angle. Similar to the 3×3 cells of the current imaging angle information mentioned above, the 3×3 imaging angle setting switches 70 show the configuration of the first X-ray source 1a and the second X-ray source 2a relative to the subject 101 when viewed from above. The imaging angle setting switch 70 at the lower left of the screen (on the right side and head side of the subject 101) that is highlighted among the nine switches is the switch selected by the user as the main X-ray source. Currently, since the first X-ray source 1a is configured in the cell at the lower left of the screen (on the right side and head side of the subject 101), Figure 5 The display is a display when setting the target imaging angle of the first X-ray source 1a.

[0057] In this state, the operator can set and register a maximum of three combinations of target imaging angles of the first X-ray source 1a and the second X-ray source 2a. In addition, since three "●" are displayed in the frame of the imaging angle setting switch 70 at the lower left of the screen, it can be understood that the three combinations of target imaging angles of the first X-ray source 1a and the second X-ray source 2a are set and registered as registered information at the current time point.

[0058] A combination 71 of three target imaging angles that have been set and registered as registered information is displayed on the right side of the 3×3 imaging angle setting switch 70. Figure 5In the state, since the combination of the target imaging angles of the third first X-ray source 1a and the second X-ray source 2a is highlighted, the target imaging angles of the first X-ray source 1a (forearm) as the main X-ray source are set to RAO 30 degrees and CRAN 30 degrees, and the target imaging angles of the second X-ray source 2a (forearm) as the auxiliary X-ray source are set to LAO 45 degrees and CAUD 30 degrees. In this state, the setting is confirmed by pressing the OK switch at the lower right of the screen.

[0059] The above RAO means right side tilt. The above LAO means left side tilt. The above CRAN is the abbreviation of CRANIAL, which means head tilt. The above CAUD is the abbreviation of CAUDAL, which means lower limb tilt.

[0060] In addition, currently, since the second X-ray source 2a is arranged in the cell at the upper right of the screen (the left side and the lower limb side of the subject 101), the second X-ray source 2a can be switched to the setting of setting the second X-ray source 2a as the main X-ray source and the first X-ray source 1a as the auxiliary X-ray source by pressing the switch at the upper right of the screen of the 3×3 imaging angle setting switch 70. In this case, among the switches of the 3×3 imaging angle setting switch 70, the switch at the upper right of the screen is highlighted instead of the switch at the lower left of the screen.

[0061] The above-mentioned "main X-ray source" is moved to the X-ray source configuration switch (memory switch) 80 (80a to 80i) selected (pressed) by the user in the configuration screen 8 during actual imaging (see Figure 7 , Figure 8 ) in a configuration. The above-mentioned “secondary X-ray source” is an X-ray source whose configuration is automatically selected when the user selects the configuration of the main X-ray source. Therefore, it is necessary to set and register the configuration of the secondary X-ray source in association with the configuration of the main X-ray source in the pre-configuration setting screen 7 in advance. In addition, the “main X-ray source” and the “secondary X-ray source” may also be either the first X-ray source 1a or the second X-ray source 2a. The X-ray source configuration switch 80 is an example of an “X-ray source configuration partition” in the claims.

[0062] The pre-configuration setting is completed by setting the combination of the target imaging angles of the first X-ray source 1a and the second X-ray source 2a for each of the nine imaging angle setting switches 70. In addition, the pre-configuration setting is not required for the imaging angle setting switches 70 that are not used during imaging.

[0063] like Figure 6 As shown in FIG. 1 , a specific example of the X-ray source arrangement information stored in the storage unit 5 a as a result of the pre-arrangement setting will be described.

In order to execute the third setting information stored, the operator selects the X-ray source configuration switch 80c (the switch at the position corresponding to the configuration of the first X-ray source 1a as the main X-ray source) in the configuration screen 8 during actual imaging.

[0067] In addition, fourth setting information is stored in the storage unit 5a, and the fourth setting information means that when the first X-ray source 1a is configured at a target imaging angle of LAO / RAO 0 degrees and CRAN 30 degrees (head side of the subject 101), the second X-ray source 2a is configured at a target imaging angle of LAO 90 degrees and CRAN / CAUD 0 degrees (left side of the subject 101). In order to execute the stored fourth setting information, the operator selects the X-ray source configuration switch 80d (a switch at a position corresponding to the configuration of the first X-ray source 1a as the main X-ray source) in the configuration screen 8 during actual imaging.

[0068] In addition, fifth setting information is stored in the storage unit 5a, and the fifth setting information means that when the first X-ray source 1a is configured at a target imaging angle of LAO / RAO 0 degrees and CRAN / CAUD 0 degrees (the front side or the back side of the subject 101), the second X-ray source 2a is configured at a target imaging angle of LAO 90 degrees and CRAN / CAUD 0 degrees (the left side of the subject 101). In order to execute the stored fifth setting information, the operator selects the X-ray source configuration switch 80e (a switch at a position corresponding to the configuration of the first X-ray source 1a as the main X-ray source) in the configuration screen 8 during actual imaging.

[0069] In addition, the sixth setting information is stored in the storage unit 5a, and the sixth setting information means that when the first X-ray source 1a is configured at the target imaging angle of LAO / RAO 0 degrees and CAUD 30 degrees (the lower limb side of the subject 101), the second X-ray source 2a is configured at the target imaging angle of LAO 90 degrees and CRAN / CAUD 0 degrees (the left side of the subject 101). In order to execute the stored sixth setting information, the operator selects the X-ray source configuration switch 80f (the switch at the position corresponding to the configuration of the first X-ray source 1a as the main X-ray source) in the configuration screen 8 during actual imaging.

[0072] In addition, the ninth setting information is stored in the storage unit 5a, and the ninth setting information means that when the second X-ray source 2a is configured at the target imaging angle of LAO 50 degrees and CAUD 30 degrees (the left side and lower limb side of the subject 101), the first X-ray source 1a is configured at the target imaging angle of RAO 20 degrees and CAUD 20 degrees (the right side and lower limb side of the subject 101). In addition, in order to execute the stored ninth setting information, the operator selects the X-ray source configuration switch 80i (the switch at the position corresponding to the configuration of the second X-ray source 2a as the main X-ray source) in the configuration screen 8 during actual imaging.

[0073] As described above, the operator selects any one of the X-ray source configuration switches 80 (80a to 80i) in the configuration screen 8, and executes each setting information as the X-ray source configuration information by selecting the position change switch 83. When the position change switch 83 is selected, the first X-ray source 1a and the second X-ray source 2a are moved to the configuration of the target imaging angle.

[0074] (About the configuration screen)

[0075] like Figure 7 and Figure 8 As shown, the display unit 3 is configured to display a configuration screen (arm configuration screen) 8, which shows the configuration corresponding to the positions of the first X-ray source 1a and the second X-ray source 2a at the target imaging angle relative to the actual position of the subject 101. Therefore, by checking the configuration screen 8, the operator can intuitively understand the approximate configuration of the first X-ray source 1a and the second X-ray source 2a relative to the subject 101 during imaging.

[0076] The display unit 3 is configured to display a plurality of (nine) X-ray source configuration switches (memory switches) 80 arranged on a configuration screen 8 of the display unit 3, and the plurality of X-ray source configuration switches 80 indicate positions where the first X-ray source 1a and the second X-ray source 2a can be configured with respect to the subject 101. In addition, the imaging angle setting unit 4 is configured by the plurality of X-ray source configuration switches 80.

[0077] Specifically, the plurality of X-ray source configuration switches 80 include only one central subject partition 81 showing a pattern 81a representing the subject 101 lying on its back, and a plurality of (eight) peripheral partitions 82 arranged so as to surround the subject partition 81 when viewed from above. The pattern 81a of the subject partition 81 is presented in such a manner that the head side faces the left side of the screen, the lower limb side faces the right side of the screen, the left upper limb faces the top of the screen, and the right upper limb faces the bottom of the screen. The plurality of X-ray source configuration switches 80 are arranged in a 3×3 (three rows and three columns) cell shape (matrix shape).

[0078] The display unit 3 is configured to display the angle in the left-right direction (angle tilted in the left-right direction relative to the vertical axis) and the angle in the body axis direction (angle tilted in the body axis direction relative to the vertical axis) relative to the subject 101 as the target imaging angle. The angle in the left-right direction is displayed in each partition of the X-ray source configuration switch 80 by the above-mentioned LAO / RAO. The angle in the body axis direction is displayed in each partition of the X-ray source configuration switch 80 by the above-mentioned CRAN / CAUD.

[0079] (Structure of control unit)

[0080] Figure 4 The control unit (display control unit) 5 shown is configured to perform the following control: when the configuration of one of the first X-ray source 1a and the second X-ray source 2a is selected and displayed in the configuration screen 8 of the display unit 3 with the help of the photographic angle setting unit 4 (X-ray source configuration switch 80), the configuration of the other of the first X-ray source 1a and the second X-ray source 2a is automatically selected and displayed.

[0081] In this case, the control unit 5 is configured to perform the following control: the partition frame line 84 of the X-ray source configuration switch 80 indicating one of the first X-ray source 1a and the second X-ray source 2a selected by the imaging angle setting unit 4 is displayed in a thicker manner than the partition frame line 84 of the X-ray source configuration switch 80 indicating the other of the first X-ray source 1a and the second X-ray source 2a. In short, the partition frame line 84 indicating the X-ray source configuration switch 80 corresponding to the configuration of the main X-ray source is thicker than the partition frame line 84 indicating the X-ray source configuration switch 80 corresponding to the configuration of the auxiliary X-ray source.

[0082] If the storage unit 5a stores Figure 6 , the control unit 5 sets the first X-ray source 1a of the forearm as the main X-ray source when any of the six X-ray source configuration switches 80a to 80f on the lower side is selected (pressed). That is, the control unit 5 sets the first X-ray source 1a to the configuration of the X-ray source configuration switch 80 actually selected by the operator. In this case, the second X-ray source 2a is automatically set as the auxiliary X-ray source.

[0083] In addition, when any one of the three X-ray source configuration switches 80g to 80i on the upper side is selected (pressed), the control unit 5 sets the second X-ray source 2a of the lateral arm as the main X-ray source. In other words, the control unit 5 sets the second X-ray source 2a to move to a predetermined configuration associated with the X-ray source configuration switch 80 actually selected by the operator. In this case, the first X-ray source 1a is automatically set as the auxiliary X-ray source.

[0084] The control unit 5 is configured to perform the following control: both the configurations of the selected first X-ray source 1a and the second X-ray source 2a are displayed in a distinguishable manner on the configuration screen 8. Specifically, the control unit 5 is configured to perform the following control: when any one of the plurality of X-ray source configuration switches 80 is selected by the imaging angle setting unit 4, the X-ray source configuration switch 80 associated with the target imaging angle of the first X-ray source 1a and the X-ray source configuration switch 80 associated with the target imaging angle of the second X-ray source 2a are simultaneously displayed on the display unit 3 in a manner distinguishable from other X-ray source configuration switches 80.

[0085] As a specific example, the storage unit 5a stores the following Figure 6 When the operator selects the X-ray source configuration switch 80a at the lower left corner of the screen (to the right side of the subject 101 and the head side) in the configuration screen 8, the control unit 5 performs the following control: automatically selects the X-ray source configuration switch 80i at the upper right corner of the screen, and displays the X-ray source configuration switches 80a and 80i on the display unit 3 at the same time in a manner that can be distinguished from other X-ray source configuration switches 80.

[0086] That is, the control unit 5 is configured to perform the following control: changing the display color of the X-ray source configuration switch 80 indicating the position of the selected first X-ray source 1a to the first identification color 9a (blue), and changing the display color of the X-ray source configuration switch 80 indicating the position of the selected second X-ray source 2a to the second identification color 9b (yellow) different from the first identification color 9a.

[0087] In this case, the control unit 5 is configured to control: using the first identification color 9a (yellow) that is the same as the first appearance color 6a (yellow) of the first arm 1 to display the X-ray source configuration switch 80 associated with the target imaging angle of the first X-ray source 1a, and using the second identification color 9b (blue) that is the same as the second appearance color 6b (blue) of the second arm 2 to display the X-ray source configuration switch 80 associated with the target imaging angle of the second X-ray source 2a.

[0088] The control unit 5 is configured to perform control to display the angle in the left-right direction and the angle in the body axis direction relative to the subject 101 as the target imaging angle within the partition frame lines 84 of each of the plurality of X-ray source arrangement switches 80 .

[0089] In this case, the control unit 5 is configured to perform the following control: before the X-ray source configuration switch 80 is selected by the imaging angle setting unit 4, the target imaging angle (the angle in the left-right direction and the angle in the body axis direction relative to the above-mentioned subject 101) of one of the first X-ray source 1a and the second X-ray source 2a is displayed in the partition frame line 84 of each of the plurality of X-ray source configuration switches 80. In short, the control unit 5 performs the following control: the target imaging angle of the main X-ray source is displayed in the partition frame line 84 of each of the plurality of X-ray source configuration switches 80. At this point in time, the target imaging angle of the auxiliary X-ray source is not displayed at all in the partition frame line 84.

[0090] Furthermore, the control unit 5 is configured to perform the following control: when any one of the plurality of X-ray source configuration switches 80 is selected and displayed by the imaging angle setting unit 4, the X-ray source configuration information (see Figure 6 ) Any one of the multiple X-ray source configuration switches 80 is automatically selected as the X-ray source configuration switch 80 that configures the other one of the first X-ray source 1a and the second X-ray source 2a and displayed, and the target imaging angle displayed within the partition frame line 84 of the automatically selected and displayed X-ray source configuration switch 80 is replaced with the target imaging angle of the other one of the first X-ray source 1a and the second X-ray source 2a.

[0091] As a specific example, if the storage unit 5a stores the following Figure 6 If the operator selects the X-ray source configuration switch 80a at the lower left of the screen (to the right side and head side of the subject 101), the control unit 5 automatically selects and displays the X-ray source configuration switch 80i at the upper right of the screen. In this case, the X-ray source configuration switch 80a indicates the configuration of the first X-ray source 1a as the main X-ray source relative to the subject 101, and the X-ray source configuration switch 80i indicates the configuration of the second X-ray source 2a as the auxiliary X-ray source relative to the subject 101. At this time, based on the X-ray source configuration information, the control unit 5 changes the target imaging angle displayed within the partition frame line 84 of the X-ray source configuration switch 80i from "LAO 50 degrees and CAUD 30 degrees (refer to Figure 7 )" is replaced by "LAO 45 degrees and CAUD 30 degrees (refer to Figure 8 )”.

[0092] In addition, the control unit 5 is configured to perform the following control: when the operator selects the above-mentioned object partition 81 arranged in the center, X-rays are irradiated from the surface or back side of the object 101 when viewed from above; when the operator selects the above-mentioned peripheral partition 82, X-rays are irradiated from the periphery of the object 101 when viewed from above.

[0093] (Control Processing Flow for Moving the X-ray Source Executed by the Control Unit)

[0094] Next, refer to Fig. 9 The following describes a control process flow for moving the X-ray source executed by the control unit (display control unit) 5. The control process flow is described starting from an initial state in which a predetermined operation for displaying the configuration screen 8 on the display unit 3 (touch panel 300) is performed.

[0095] In the initial state, a plurality of X-ray source configuration switches 80 are displayed in a 3×3 pattern on the configuration screen 8. In the initial state, a target imaging angle of the main X-ray source is displayed in each section of the plurality of X-ray source configuration switches 80.

[0096] First, in step S1, it is determined whether any one of the plurality of X-ray source configuration switches 80 is operated (pressed). If any one of the plurality of X-ray source configuration switches 80 is operated, the process proceeds to step S2.

[0097] In step S2, the X-ray source configuration switch 80 indicating the main X-ray source that has been operated is displayed using the first identification color 9a (in a manner that can be distinguished from other X-ray source configuration switches 80). At this time, the partition frame line 84 of the X-ray source configuration switch 80 is displayed in bold. As an example, in Figure 8 2 shows a case where the X-ray source arrangement switch 80a on the right side and the head side of the subject 101 is operated. Then, the process proceeds to step S3.

[0098] In step S3, based on the X-ray configuration information stored in the storage unit 5a (see Figure 6 ), the X-ray source configuration switch 80 representing the auxiliary X-ray source is displayed using the second identification color 9b (in a manner that can be distinguished from other X-ray source configuration switches 80). As an example, in Figure 8 2 shows a case where the X-ray source arrangement switch 80i on the left side and the lower limb side of the subject 101 is automatically selected and displayed. Then, the process proceeds to step S4.

[0099] In step S4, the target imaging angle of the main X-ray source displayed in the partition of the X-ray source configuration switch 80 representing the auxiliary X-ray source is replaced with the target imaging angle of the auxiliary X-ray source. Figure 7 The angle change shown is Figure 8 Then, the process proceeds to step S5.

[0100] In step S5, it is determined whether the position change switch 83 has been operated (pressed). If the position change switch 83 has been operated, the process proceeds to step S6.

[0101] In step 6, the first X-ray source 1a is moved to the target imaging angle, and the second X-ray source 2a is moved to the target imaging angle.

[0102] As a specific example, in step S1, if the X-ray source configuration switch 80a is operated, the first X-ray source 1a as the main X-ray source is moved to the target imaging angle of RAO 30 degrees and CRAN 30 degrees (the right side and the head side of the subject 101). In addition, the second X-ray source 2a as the auxiliary X-ray source is moved to the target imaging angle of LAO 45 degrees and CAUD 30 degrees (the left side and the lower limb side of the subject 101). The above is the control processing flow for moving the X-ray source executed by the control unit 5.

[0103] [Effects of this embodiment]

[0104] In this embodiment, the following effects can be obtained.

[0105] In the present embodiment, as described above, the display unit 3 is configured to display a configuration screen 8 showing a configuration corresponding to the positions of the first X-ray source 1a and the second X-ray source 2a at the target imaging angle relative to the actual position of the subject 101. Thus, according to the configuration screen 8, the positions of the first X-ray source 1a and the second X-ray source 2a relative to the subject 101 can be understood through an image that can be visually confirmed like a map. In addition, the imaging angle setting unit 4 and the display unit 3 are provided in the same configuration area 103 of the X-ray imaging device main body 100a. Thus, the imaging angle setting unit 4 and the display unit 3 can be confirmed without moving the line of sight. As a result of the above, the operation for moving the first X-ray source 1a and the second X-ray source 2a can be performed without moving the line of sight, and the operation for moving the first X-ray source 1a and the second X-ray source 2a can be performed intuitively.

[0106] In this embodiment, as described above, the imaging angle setting unit 4 and the display unit 3 are integrally configured as the touch panel 300. Thus, the touch panel 300 can simplify the device structure for displaying and operating (setting) required to move the first X-ray source 1a and the second X-ray source 2a.

[0107] In addition, in the present embodiment, as described above, the control unit 5 is further provided, and the control unit 5 performs the following control: when the configuration of one of the first X-ray source 1a and the second X-ray source 2a is selected and displayed by the imaging angle setting unit 4 on the configuration screen 8 of the display unit 3, the configuration of the other of the first X-ray source 1a and the second X-ray source 2a is automatically selected and displayed. As a result, the operator does not need to select the configuration of the other of the first X-ray source 1a and the second X-ray source 2a, and the operation burden can be reduced.

[0108] In addition, in the present embodiment, as described above, the control unit 5 is configured to perform the following control: the configurations of both the selected first X-ray source 1a and the second X-ray source 2a are displayed in a discernible manner on the configuration screen 8. Thus, the operator can visually easily discern the configurations of the selected first X-ray source 1a and the second X-ray source 2a on the configuration screen 8. As a result, the operation for moving the first X-ray source 1a and the second X-ray source 2a can be performed more intuitively.

[0109] In addition, in the present embodiment, as described above, the display unit 3 is configured to display a plurality of X-ray source configuration switches 80 (80a to 80i) arranged on the configuration screen 8 of the display unit 3, the plurality of X-ray source configuration switches 80 indicating positions at which the first X-ray source 1a and the second X-ray source 2a can be configured with respect to the subject 101, and the control unit 5 is configured to perform the following control: when any one of the plurality of X-ray source configuration switches 80 is selected by the imaging angle setting unit 4, the X-ray source configuration switch 80 associated with the target imaging angle of the first X-ray source 1a and the X-ray source configuration switch 80 associated with the target imaging angle of the second X-ray source 2a are simultaneously displayed on the display unit 3 in a manner distinguishable from other X-ray source configuration switches 80. Thus, among the plurality of X-ray source configuration switches 80, the switch at which the first X-ray source 1a is configured, the switch at which the second X-ray source 2a is configured, and the other switches can be visually easily distinguished.

[0110] In addition, in the present embodiment, as described above, the control unit 5 is configured to perform the following control: the display color of the X-ray source configuration switch 80 indicating the position where the selected first X-ray source 1a is configured is changed to the first identification color 9a, and the display color of the X-ray source configuration switch 80 indicating the position where the selected second X-ray source 2a is configured is changed to the second identification color 9b different from the first identification color 9a. Thus, by changing the display method of the display color, the positions where the selected first X-ray source 1a and the second X-ray source 2a are configured can be easily distinguished.

[0111] In addition, in the present embodiment, as described above, the first arm 1 is colored with the first appearance color 6a, and the second arm 2 is colored with the second appearance color 6b different from the first appearance color 6a, and the control unit 5 is configured to perform the following control: the X-ray source configuration switch 80 associated with the target imaging angle of the first X-ray source 1a is displayed using the first identification color 9a that is the same as the first appearance color 6a of the first arm 1, and the X-ray source configuration switch 80 associated with the target imaging angle of the second X-ray source 2a is displayed using the second identification color 9b that is the same as the second appearance color 6b of the second arm 2. Thus, the first X-ray source 1a and the second X-ray source 2a arranged around the subject 101 can be associated with the X-ray source configuration switches 80 of the first X-ray source 1a and the second X-ray source 2a, respectively, using the first identification color 9a and the second identification color 9b. As a result, the positions where the selected first X-ray source 1a and the second X-ray source 2a are arranged can be more easily identified.

[0112] In addition, in the present embodiment, as described above, the control unit 5 is configured to perform the following control: the partition frame line 84 of the X-ray source configuration switch 80 indicating one of the first X-ray source 1a and the second X-ray source 2a selected by the imaging angle setting unit 4 is displayed in a thicker manner than the partition frame line 84 of the X-ray source configuration switch 80 indicating the other of the first X-ray source 1a and the second X-ray source 2a. As a result, the operator can easily visually distinguish the partition frame line 84 of the X-ray source configuration switch 80 indicating one of the first X-ray source 1a and the second X-ray source 2a selected by the operator by the imaging angle setting unit 4, and the partition frame line 84 of the X-ray source configuration switch 80 indicating the other of the first X-ray source 1a and the second X-ray source 2a.

[0113] In addition, in the present embodiment, as described above, a storage unit 5a is further provided, which stores X-ray source configuration information that establishes an association between the configurations of the first X-ray source 1a and the second X-ray source 2a, and the control unit 5 is configured to perform the following control: before the X-ray source configuration switch 80 is selected by means of the imaging angle setting unit 4, the target imaging angle of one of the first X-ray source 1a and the second X-ray source 2a is displayed in the partition frame line 84 of each of the plurality of X-ray source configuration switches 80; when any one of the plurality of X-ray source configuration switches 80 is selected and displayed by means of the imaging angle setting unit 4, any one of the plurality of X-ray source configuration switches 80 is automatically selected as the X-ray source configuration switch 80 that configures the other of the first X-ray source 1a and the second X-ray source 2a based on the X-ray source configuration information and is displayed, and the target imaging angle displayed in the partition frame line 84 of the automatically selected and displayed X-ray source configuration switch 80 is replaced with the target imaging angle of the other of the first X-ray source 1a and the second X-ray source 2a. Thus, since the target imaging angle displayed in the partition frame line 84 of the X-ray source configuration switch 80 that is automatically selected and displayed can be replaced with the target imaging angle of the other of the first X-ray source 1a and the second X-ray source 2a, the workload of replacing the target imaging angle with the other of the first X-ray source 1a and the second X-ray source 2a can be reduced. In addition, the target imaging angle of the other of the first X-ray source 1a and the second X-ray source 2a can be easily confirmed.

[0114] In addition, in the present embodiment, as described above, the plurality of X-ray source arrangement switches 80 include one subject partition 81 showing a pattern 81a representing the subject 101, and a plurality of peripheral partitions 82 arranged so as to surround the periphery of the subject partition 81, and the control unit 5 is configured to perform the following control: when the subject partition 81 is selected, X-rays are irradiated from the front or back of the subject 101 when viewed from above, and when the peripheral partition 82 is selected, X-rays are irradiated from the periphery of the subject 101 when viewed from above. Thus, each X-ray source arrangement switch 80 can be associated with the posture and direction of the subject 101 and can be easily grasped.

[0115] In addition, in the present embodiment, as described above, the display unit 3 is configured to display the angle in the left-right direction and the angle in the body axis direction relative to the subject 101 as the target imaging angle, and the control unit 5 is configured to perform the following control: the angle in the left-right direction and the angle in the body axis direction relative to the subject 101 are displayed as the target imaging angle within the partition frame line 84 of each of the plurality of X-ray source configuration switches 80. Thus, the angle in the left-right direction and the angle in the body axis direction can be displayed separately, so that the configuration of the X-ray source relative to the subject 101 can be easily grasped.

[0116] In addition, in the present embodiment, as described above, the display unit 3 is configured to be able to display the preconfiguration setting screen 7 and the configuration screen 8, wherein the preconfiguration setting screen 7 is used to perform settings for associating the configurations of the first X-ray source 1a and the second X-ray source 2a with each other and setting the target imaging angles of the first X-ray source 1a and the second X-ray source 2a, and the configuration screen 8 is a screen based on the information set in the preconfiguration setting screen 7. Thus, according to the preconfiguration setting screen 7 and the configuration screen 8, both the operation of setting the target imaging angles of the first X-ray source 1a and the second X-ray source 2a and the operation of setting the configurations of the first X-ray source 1a and the second X-ray source 2a can be easily performed.
