In this case, the height of the apparatus increases by an amount corresponding to the fact that the support arm 69 is higher than the X-ray tube 63 (the distance marked by L in the figure), so that the installation space for allowing the top plate 61 to stand up and down is increased.
[0006] In addition, when the height of the device is to be suppressed, the amount of sliding of the support arm 69 relative to the pillar 67 is reduced, and a sufficient amount of stroke of the X-ray tube 63 cannot be ensured.
As a result, for example, if the distance between the focal films cannot be enlarged, blurring occurs in the obtained image, and chest X-ray imaging cannot be performed properly
In addition, if the distance between the focal films cannot be shortened, it is not possible to properly perform gastrointestinal diagnosis, etc.

Embodiment 1
[0066] Next, Embodiment 1 of the present invention will be described with reference to the drawings. figure 1 It is the front view of the X-ray fluoroscopy apparatus of an Example. also, figure 1 (a), (b), and (c) represent the state that the top plate is horizontal, inclined, and vertical, respectively.
[0067] The X-ray fluoroscopy device of the present embodiment has: base 1, top board support body 3 (hereinafter referred to simply as main frame), top board 5, pillar 7, middle slider 11, supporting arm 15, X-ray tube 17 and Cassette19. The base 1 is mounted on a floor surface, and includes a pinion gear 21 that is rotationally driven around a horizontal axis by a drive mechanism (not shown). The main frame 3 has a sector rack (gear) 23 meshing with the pinion 21 , is supported by the base 1 , and rotates about a horizontal axis by the rotation of the pinion 21 . The top plate 5 is held by the main frame 3 , and moves up and down in unison with the rotation of the mai...

A radiographic X-ray equipment comprising a slide arm supporting an X-ray tube, an intermediate slider holding a supporting arm movably in the direction of the irradiation axis of an X-ray generation source, and a column for holding the intermediate slider movably in the direction of the irradiation axis, wherein the distances of movement of the intermediate slider and the supporting arm can be made small as compared with the quantity of stroke of the X-ray tube, and the height of the equipment can be reduced by shortening the column, the intermediate slider and the supporting arm. Consequently, the quantity of stroke of the X-ray generation source can be ensured appropriately while an increase in installation space is suppressed.
Description
technical field [0001] The present invention relates to an X-ray fluoroscopy device for performing fluoroscopy on an object to be inspected, and particularly relates to a technique for moving an X-ray source far or near relative to an imaging device. Background technique [0002] At present, there are X-ray fluoroscopy devices that can not only diagnose the digestive tract such as the stomach, but also perform chest X-rays. However, it is necessary to maintain a longer distance from the X-ray source to the imaging device (hereinafter abbreviated as Focus Film Distance (FFD: Focus Film Distance)) in chest X-ray imaging than in digestive tract diagnosis. For example, it is about 1.1 m for alimentary tract diagnosis, and about 1.8 to 2.0 m for chest X-ray imaging. Figure 10 A conventional X-ray fluoroscopic apparatus is shown, which is configured to perform multipurpose fluoroscopic imaging. Figure 10 It is a front view of a conventional X-ray fluoroscopy apparatus, (a) shows...
