  • X-ray fluoroscopic apparatus
    Patent number: 8382371
    Abstract: The X-ray fluoroscopic apparatus of this invention includes a slide arm for supporting an X-ray tube, a middle slider for holding the support arm to be movable in directions along an irradiation axis of the X-ray source, and a strut for holding the middle slider to be movable the directions along the irradiation axis. Thus, compared with an amount of stroke of the X-ray tube, an amount of movement of each of the middle slider and the support arm can be small, and each of the strut, middle slider and support arm can be shortened to reduce apparatus height. Therefore, the amount of stroke of the X-ray source can be secured appropriately, while inhibiting an increase in installation space.
    Type: Grant
