The video system device 3 such as a cassette or a cassette is mechanically connected to the X-ray tube support device 6 so as to face each other and is mechanically connected.
When the inside was moved horizontally, the X-ray tube 2 was also moved horizontally. Further, the X-ray tube supporting device 6 and the X-ray tube 2 were moved following the up and down movement of the imaging table 1 and the horizontal movement of the top plate 5. These follow-up operations are performed by the control device 20, and the photographing table drive control section 9 for controlling the raising and lowering of the photographing table 1 and the horizontal movement of the image system device 3 and the top plate 5, the operation range of each section, and the like. The console 14 includes a position control unit 13 that controls position interference prevention, a tilt switch 15 that operates the imaging stand 1, and a video system operation switch 16 that operates the video system device 3. When the imaging table 1 is moved by the tilt switch 15, the imaging table 1 and the X-ray tube supporting device 6 are mechanically connected to each other, so that the X-ray tube 2 follows the tilting motion of the imaging table 1 and a further image. When the image system device 3 is moved in the longitudinal direction of the top 5 by the image system operation switch 16, the image system device 3 and the X-ray tube supporting device 6 are mechanically connected to each other. The X-ray tube 2 follows the movement.

[0003]

In the above-mentioned conventional X-ray fluoroscopic imaging table, since the X-ray tube constituting the fluoroscopic imaging table and the image system apparatus are mainly opposed to each other, fluoroscopic imaging is performed, so that chest imaging and Bucky imaging are performed. When performing each, it is necessary to take an image in a dedicated room using a dedicated imaging device, and when performing a plurality of images, the subject has to move for each imaging, which is a burden. Was there.

Therefore, an object of the present invention is to share the X-ray tube of the fluoroscopic imaging table with a plurality of imaging devices to simplify the device and improve the diagnostic efficiency.

[0005]

In order to achieve the above object, an X-ray tube device, a top plate on which a subject is laid, and a video system device for converting transmitted X-rays of the subject into an image are provided. An imaging stand for horizontally moving and tilting the top plate and the image system device, and an X-ray tube for interlocking the position of the X-ray tube device corresponding to the horizontal motion and tilting motion of the top plate and the image system device. A supporting device and the X
In an X-ray fluoroscopic imaging stand having a X-ray tube apparatus, an imaging stand, and a control unit for controlling the operation of the X-ray tube supporting apparatus, the X-ray tube supporting apparatus is separated from the X-ray tube apparatus and is independent of the X-ray tube apparatus. And a position detector for supporting the X-ray tube support device and the X-ray tube device, respectively, and detecting the positions of the imaging table and the top plate or the positions of the imaging device other than the imaging table, Means for causing the apparatus to perform follow-up interlocking operation of the X-ray tube support device and the X-ray tube apparatus by an output signal of the position detector of the imaging table or the position detector of the imaging apparatus; It is provided with selection means for making a selection.

[0006]

The function of selecting the photographing device to be used is selected by the means for selecting the photographing table and the photographing device, and after the selection, when the photographing table is used, the moving position of the photographing table and the top plate is detected by the position detector. The detection is performed, and the X-ray tube supporting device and the X-ray tube are caused to follow the detection signal. When the imaging device is used, the vertical movement of the imaging device is detected by the position detector, and the detection signal causes the X-ray tube support device and the X-ray tube to follow.
This makes it possible to improve the efficiency of shooting for multiple models.
