These X-ray irradiation unit, X-ray detection unit, and C-type arm 13 constitute an imaging unit according to the present invention.

  The C-shaped arm 13 has an arc shape and supports an X-ray irradiation unit and an X-ray detection unit. The C-shaped arm 13 is slidably supported with respect to the arm support portion 14. Further, the arm support portion 14 is rotatable about an axis that faces the support portion 15 in the horizontal direction. Further, the support portion 15 is supported so as to be movable in the horizontal direction and the vertical direction with respect to the apparatus main body 11. The movement of the C-arm 13 is executed by the operator holding and moving a handle (not shown).

  The X-ray fluoroscopic apparatus includes a pair of support portions 95 and 96 disposed on the C-shaped arm 13. A projector screen 90 is supported on one of the support portions 95 and 96. 1 and 3 show a state in which the projector screen 90 is supported by the support portion 95 of the pair of support portions 95 and 96, but the C-arm 13 is shown in FIGS. 1 and 2. When rotated 180 degrees from the state, the projector screen 90 is supported by the support 96.

  The X-ray fluoroscopic apparatus includes a projector 80 disposed on the C-arm 13. The projector 80 and the projector screen 90 are of a rear projection type for displaying an X-ray image from the back side of the projector screen 90.

The screen body 91 is pulled out from the winding unit 92 by operating the handle 94, and is operated again by operating the handle 94 by the action of a spring (not shown) disposed in the winding unit 92. It is wound up in the take-up portion 92.

  FIG. 5 is a schematic diagram of the projector 80.

  The projector 80 includes a base part 82 and a projection part 81. The projection unit 81 can rotate and swing with respect to the base 82. For this reason, it is possible to change the projection angle or the projection position of the image projected from the projector 80.

  FIG. 6 is a block diagram showing a main control system of the fluoroscopic imaging apparatus according to the present invention.

  This X-ray fluoroscopic apparatus includes a control unit 50 that controls the entire apparatus. The control unit 50 is connected to the X-ray irradiation unit 20 including the X-ray tube 21 and the collimator 23 described above, the X-ray detection unit 30 including the image intensifier 32 and the camera 33, and the projector 80. Yes. In addition, the control unit 50 includes an image processing unit 51 that performs image processing on an X-ray fluoroscopic image or an X-ray photographed image detected by the X-ray detection unit 30. As will be described later, the image processing unit 51 changes the projection angle or projection position of the X-ray image projected from the projector 80 onto the screen body 91 on the projector screen 90 based on the posture of the C-arm 13. The unit 52 is provided.

  When performing X-ray fluoroscopy or X-ray imaging in the X-ray fluoroscopic imaging apparatus having the above-described configuration, the engaging portions in the projector screen 90 are made to the support portions 95 and 96 disposed on the C-arm 13. By engaging 93, the projector screen 90 is supported by the support portions 95 and 96. At this time, as shown in FIGS. 1 and 2, when the X-ray irradiation unit 20 having the X-ray tube 21 and the collimator 23 is arranged on the upper side to perform X-ray fluoroscopy or X-ray imaging, the projector screen 90 is used. The support portion 95 supports the fishing. On the other hand, when the X-ray detection unit 30 composed of the image intensifier 32 and the camera 33 is arranged on the upper side to perform X-ray fluoroscopy or X-ray imaging, the projector screen 90 is supported by the support unit 96. Then, the screen body 91 in the projector screen 90 is pulled out from the winding unit 92.

  X-ray fluoroscopy or X-ray imaging is performed in this state. At this time, X-rays irradiated from the X-ray tube 21 and whose X-ray irradiation field is limited by the collimator 23 are irradiated to the subject 100 on the table 19, and the X-rays passing through the subject 100 are image intensifiers. 32 and the camera 33. Then, the X-ray image is transmitted to the image processing unit 51 in the control unit 50. In the image processing unit 51, the brightness, contrast, focus, and the like of the X-ray image are adjusted, and an X-ray image signal is transmitted to the projector 80.

  Then, an X-ray image is projected from the projector 80 toward the screen body 91 of the projector screen 90. At this time, since the projector 80 and the projector screen 90 are of a rear projection type for displaying an X-ray image from the back side of the projector screen 90, as shown in FIG. An X-ray image projected on the screen main body 91 can be observed from the opposite side of the projector 90 with respect to the screen 90.

At this time, since the projector screen 90 is supported by the support portion 95, the projector screen 90 is in a fixed posture regardless of the rotational angle position of the C-arm 13. On the other hand, since the projector 80 is attached to the C-type arm 13, it rotates together with the C-type arm 13. Therefore, the projection image changing unit 52 in the image processing unit 51 changes the projection angle of the X-ray image projected from the projector 80 onto the screen body 91 on the projector screen 90 based on the rotation angle position of the C-arm 13. .

  Similarly, the C-shaped arm 13 may slide with respect to the arm support portion 14. Also at this time, the projection image changing unit 52 in the image processing unit 51 changes the projection position of the X-ray image projected from the projector 80 to the screen body 91 on the projector screen 90 based on the slide position of the C-arm 13. To do. The change of the projection angle and the projection position may be automatically executed by the projection image changing unit 52 in the image processing unit 51, or may be executed by the operator 101 operating a switch or the like.

  According to the X-ray fluoroscopic imaging apparatus having such a configuration, an X-ray image is projected onto the projector screen 90 that is supported by the C-shaped arm 13 that constitutes the imaging unit. It is not necessary to install in the room, and the space occupied by the X-ray fluoroscopic apparatus in the operating room can be reduced.

  Next, another embodiment of the present invention will be described.
