  However, the conventional example having such a configuration has the following problems. That is, when operating the C-arm carriage 102, the operator OP may want to confirm a perspective image displayed on the monitor 121 of the monitor carriage 103. For example, when the operator OP receives an instruction from the operator PR such as the position of the C arm 107 and the brightness of the image in order to obtain a necessary image during the operation. At that time, the operator OP operates the C-arm carriage 102 based on an instruction from the operator PR. At this time, the two monitors 121 and 122 are arranged at positions where the surgeon PR can easily see, and the screen of the monitor 121 is not visible or difficult to see from the operator OP due to the arrangement relationship with other devices. Often turned to an angle. Therefore, the operator OP who has received an instruction from the surgeon PR needs to go to see a fluoroscopic image displayed on the monitor 121 for each operation. Work such as treatment is inefficient due to the trouble of confirmation of the operator OP.

  The present invention has been made in view of such circumstances, and is a mobile type capable of improving the information transmission performed between the operator and the operator and improving the work efficiency. An object is to provide an X-ray imaging apparatus.

As described above, the image acquired by the C-arm cart 2 is displayed by the monitor cart 3. The monitor cart 3 includes two monitors 21 and 22 that display acquired images. As the monitors 21 and 22, for example, a liquid crystal display or a plasma display is used. The two monitors 21 and 22 are each supported by a monitor support portion 23, and the monitor support portion 23 is supported by a monitor support carriage 25. In addition, the monitor support carriage 25 can freely move the location of the monitor carriage 3. The monitors 21 and 22 correspond to the display unit of the present invention, and the monitor support unit 23 corresponds to the support unit of the present invention.

  FIG. 2A to FIG. 2C are plan views of the monitor carriage 3. FIG. 2A shows a state in which the two monitors 21 and 22 face the same direction (front). The monitor support unit 23 supports the two monitors 21 and 22 so that the orientations of the two monitors 21 and 22 can be changed. That is, the two monitors 21 and 22 are supported by the monitor support portion 23 so as to be able to rotate around the axes s1 and s2 which are vertical directions in FIGS. 2 (a) to 2 (c). Assuming that the rotation in the direction in which the two monitors 21 and 22 face each other is the inside, the monitors 21 and 22 are configured to rotate outward by the monitor support unit 23. FIG. 2B is a diagram showing a state in which only the monitor 22 is rotated outward to change the orientation of the monitor 22.

The support members 23a and 23b are provided with angle detection sensors 27a and 27b (see FIG. 3) so that the orientations of the monitors 21 and 22 can be detected. That is, the angle detection sensors 27a and 27b are individually provided on the two monitors 21 and 22. Examples of the angle detection sensors 27a and 27b include a potentiometer and a rotary encoder.

  FIG. 3 is a block diagram for explaining display control of the monitor truck 3. The monitor cart 3 includes a display control unit 29 that controls the display of the two monitors 21 and 22. The orientation of the left monitor 21 is detected by the angle detection sensor 27a, and the orientation of the right monitor 22 is detected by the angle detection sensor 27b. The angle detection signals T1 and T2 of the angle information of the angle detection sensors 27a and 27b are sent to the display control unit 29. The display control unit 29 changes the direction of at least one of the two monitors 21 and 22 detected by the angle detection sensors 27a and 27b so that the two monitors 21 and 22 face different directions at a preset angle. Is determined. That is, the display control unit 29 determines that at least one of the two monitors 21 and 22 is larger than a preset angle with respect to the state of facing the front of FIG. In FIG. 2B and FIG. 2C, the display control unit 29 determines that each of the angles u1 to 3 (absolute values) is larger than a preset angle.

  Next, the operation of the display control unit 29 will be described. An image is acquired by irradiating the subject M with X-rays by the C-arm carriage 2, and the acquired images are displayed on the two monitors 21 and 22 of the monitor carriage 3. At this time, it is assumed that the two monitors 21 and 22 of the monitor carriage 3 face the same direction as shown in FIG. In general, the left monitor 21 is configured to display a perspective image (live image) A, and the right monitor 22 is configured to display a captured image B. In the present embodiment, similarly to this example, the display control unit 29 controls to display the fluoroscopic image A on the left monitor 21 and the captured image B on the right monitor 22. The captured image B displayed on the right monitor 22 is not updated and the same still image continues to be displayed until the next shooting is performed.

  Here, for example, as shown in FIG. 2 (b), the right monitor 22 is rotated around the axis s 2 out of the two monitors 21 and 22 facing the direction (frontal direction) of the operator PR, It is assumed that the right monitor 22 is directed to the operator OP of the C-arm carriage 2. Then, the display control unit 29 detects the change in the direction of the right monitor 22, that is, the rotation of the right monitor 22 through the angle detection sensor 27b.

  Here, the display control unit 29 performs a characteristic operation in the present invention. That is, the display control unit 29 displays the right monitor 22 when the two monitors 21 and 22 face different directions at a preset angle based on the orientation of the monitor 22 detected by the angle detection sensor 27b. Switch. As a result, the same perspective image A is displayed on the two monitors 21 and 22. That is, the display control unit 29 determines that the right monitor 22 is facing the front from the state in which the right monitor 22 is facing the front, and automatically displays the same perspective image A on the two monitors 21 and 22. To do. Thereby, the operator OP and the operator PR who are in different positions can simultaneously see the same perspective image A.

  When the two monitors 21 and 22 are returned to the same direction as shown in FIG. 2A, the right monitor 22 whose orientation has been changed is again displayed by the display control unit 29. A perspective image A is displayed on 21, and a captured image B is displayed on the right monitor 22.

  In the present embodiment, the display control unit 29 displays the same perspective image A on the two monitors 21 and 22. However, the same captured image B may be displayed on the two monitors 21 and 22. Good. In this case, the same captured image B is displayed on the two monitors 21 and 22 until the next capturing is performed. Further, the display control unit 29 may include a changeover switch for displaying one of the fluoroscopic image A and the captured image B.

  According to the present embodiment, the C-arm carriage 2 is equipped with an X-ray tube 5 and an X-ray detector 6, and the monitor carriage 3 is equipped with two monitors 21 and 22 for displaying images. The monitor support unit 23 supports the monitors 21 and 22 so that the orientations of the monitors 21 and 22 can be changed, and the angle detection sensors 27a and 27b detect the orientations of the two monitors 21 and 22. Then, the display control unit 29 displays different images (the perspective image A and the captured image B) that are in the same direction based on the directions of the two monitors 21 and 22 detected by the angle detection sensors 27a and 27b. When the orientations of the two monitors 21 and 22 are changed, the display of the two monitors 21 and 22 is switched to display the same image (for example, a perspective image) on the two monitors 21 and 22. Yes.

  That is, when the orientations of the two monitors 21 and 22 are changed, the same image is displayed on the two monitors 21 and 22. Since the same image is displayed on the two monitors 21 and 22, for example, the operator PR and the operator OP at different positions can see the same image as shown in FIG. That is, the surgeon PR performing the operation on the subject M can see the image (for example, the fluoroscopic image A) displayed on one monitor 21, and the same image (the fluoroscopic image A) displayed on the other monitor 22. Can be viewed by an operator OP who operates the C-arm carriage 2. Therefore, the operator OP does not have to go to the monitor 21 each time an instruction from the operator PR is given, and can quickly operate the C-arm carriage 2 in response to the instruction from the operator PR. Thereby, the trouble of confirmation of the operator OP is saved, and the treatment can be performed efficiently.

  When at least one of the two monitors 21 and 22 is changed, the display control unit 29 causes the two monitors 21 and 22 to display one of the same perspective image A and captured image B. . Thereby, for example, the operator PR and the operator OP at different positions can see either one of the same perspective image A and the same captured image B.

  The present invention is not limited to the above embodiment, and can be modified as follows.

  (1) In the above-described embodiment, an example is shown in which the same perspective image A is displayed on the two monitors 21 and 22 when the two monitors 21 and 22 face different directions at a preset angle. In addition to this configuration, the present invention may display a new captured image B on both the two monitors 21 and 22 for a certain period when the operator newly captures the captured image B. Note that the fluoroscopic image A is displayed again on the two monitors 21 and 22 after a predetermined time has elapsed.

  That is, the display control unit 29 displays the same perspective image A on the two monitors 21 and 22 when the orientation of at least one of the two monitors 21 and 22 is changed. Then, when the captured image B is newly acquired by the C-arm carriage 2, the display control unit 29 displays the newly acquired captured image B instead of the perspective image A for a preset period. Thereby, for example, the operator PR and the operator OP at different positions can automatically switch and view the same perspective image A and captured image B.

  (2) In the embodiment and the modification example (1) described above, the display control unit 29 displays either one of the same perspective image A and captured image B on the two monitors 21 and 22. In this regard, the display control unit 29 may display the same perspective image A and captured image B on both the two monitors 21 and 22. In FIG. 5A, the fluoroscopic image A is displayed on the left monitor 21 and the captured image B is displayed on the right monitor 22. When the orientation of the right monitor 22 is changed, the display control unit 29 divides the screen into the left and right sides of the two monitors 21 and 22 as shown in FIG. Is displayed separately. Thereby, for example, the operator PR and the operator OP at different positions can see the same perspective image A and captured image B. This embodiment is applicable to a monitor in which the two monitors 21 and 22 are horizontally long. In the case of a vertically long monitor, the same perspective image A and captured image B may be divided and displayed by dividing the screen vertically.

  (3) In the above-described embodiments and modifications (1) and (2), the orientations of the two monitors 21 and 22 are detected by the angle detection sensors 27a and 27b. In this regard, the angle detection sensor may be provided only in one of the two monitors 21 and 22. For example, it is assumed that only the right monitor 22 is provided with the angle detection sensor 27b. For example, assume that the orientation of the right monitor 22 is changed from the state of facing the front as shown in FIG. The display control unit 29 determines that the orientation of the right monitor 22 is larger than a preset angle with respect to the state in which the right monitor 22 faces the front, and displays the same image on the two monitors 21 and 22. Like that.

  (4) In the above-described embodiment and modifications (1) and (2), the orientation of each of the two monitors 21 and 22 is detected by the angle detection sensors 27a and 27b, and the display control unit 29 has two monitors. It is determined that at least one of the directions 21 and 22 is larger than a preset angle with respect to the state of facing the front shown in FIG. In this regard, the display control unit 29 calculates the angle difference (u2-u3) between the angle detection signals T1 and T2 detected by the two angle detection sensors 27a and 27b (see FIG. 2C), and the angle difference. When (u2-u3) is larger than a preset angle, the same image may be displayed on the two monitors 21 and 22. That is, the display control unit 29 determines that the two monitors 21 and 22 are facing different directions at a preset angle based on the angle difference between the directions of the two monitors 21 and 22.

  (5) In the above-described embodiments and modifications, as described above, a potentiometer or a rotary encoder is used as the angle detection sensors 27a and 27b. In this respect, for example, a switch such as a limit switch may be used. This switch is provided in each of the two monitors 21 and 22. As shown in FIG. 2A, the two switches are turned on when the monitors 21 and 22 are facing the front. In this state, as shown in FIGS. 2B and 2C, when the orientation of the monitors 21 and 22 is changed from the front, the switch attached to the changed monitor is turned off. Has been. When at least one of the two switches individually provided on the two monitors 21 and 22 is OFF, the display control unit 29 faces the two monitors 21 and 22 in different directions with a preset size. It is determined.

  (6) Although the C-arm carriage 2 is illustrated as the X-ray imaging carriage in the above-described embodiments and modifications, the X-ray imaging carriage is an X-ray tube 5 and an X-ray detector other than the C-arm 7. 6 may be configured to be supported. For example, the X-ray detector 6 mounted on the X-ray imaging cart is not supported by the support unit, and can be freely arranged from the X-ray imaging cart so as to transmit an image by wire or wirelessly. It may be a form. That is, the present invention is applicable as long as an image is displayed on the monitor carriage 3.
