  • Patent number: 11786189
    Abstract: An X-ray shielding unit 19 includes a plurality of shielding slats, freely movable with an imaging system that is in place above a table, and each free end of the shielding slats extends toward the table and is the slats are arrayed in parallel along the long side of the table. A shielding switching element switches the X-ray shielding unit between a shielding state in which the X-ray exposure to the operator S is blocked and a releasing state. The shielding switching element includes a slat rotation mechanism rotating respective shielding slats on a short side axis of the table, and the slat rotation mechanism rotates the shielding slats during switching of the shielding state.
    Type: Grant

  • Patent number: 10813610
    Abstract: A proximity operation fluoroscopic imaging apparatus allows a retreating operation for a X-ray detection element at an arbitrarily-positioned height. The X-ray imaging is carried out using the proximity operation fluoroscopic imaging apparatus a hanging-type X-ray irradiation element, a deck unit 26, supporting a flat panel detector 13, moves to a retreating position. The deck unit 26, supports a flat panel detector 13, and enables a retreating operation in the area of a subject M side of a tower unit 25, so that such a retreating operation is feasible regardless a height-position of the deck unit 26 supports the flat panel detector 13.

  • Patent number: 9480442
    Abstract: An accessory mounting device and system for the same, particularly involving radiographic systems, includes a feature to securely recognize a fixing condition of an accessory. In mounting a platform to a table, a fixing member is oscillated or moved so that the platform moves to an engagement position. A pin installed at a tip of the fixing member engages a fixing element formed in the table. Then, a movement restriction member is oscillated so that it can move to a restriction position. An oscillating movement of the movement restriction member is restricted by moving a lock-pin. Alternatively, a fixing member in a movable non-lock-state allows a display region recognizable from a display position.
