  • Publication number: 20220054099
    Abstract: An X-ray detector holder stand maintaining the position of a detector is proposed. A pillar erected on a base has a sliding window formed on the front surface of a pillar housing to extend upwards/downwards. A rack is fixed inside the pillar housing to extend perpendicularly. A wire is wound around multiple pulleys to extend perpendicularly to the front/rear side of the rack. A balance weight is coupled to the wire behind the rack inside the pillar housing. An arm includes a sliding block guided along the sliding window, a stopper gear coupled to the sliding block to rotate between a locking position and an unlocking position, an elastic pressurizing means for pressurizing the stopper gear to rotate to the locking position, and a lever means for rotating/operating the stopper gear to the unlocking position. A holder is coupled to an end portion of the arm to enable rotational manipulation.

  • Publication number: 20150313570
    Abstract: The present invention relates to an operation switch for use on an X-ray system and to an X-ray system including same. The operation switch, which includes a button part for operating a generator for driving an X-ray tube, includes: a switch body part; a link part which is formed so as to extend integrally with the button part and which is slid along the outer side surface of the switch body part when the button part is under a pressing operation; a switching means for being switched when the link part slides; and a transmission means for generating and transmitting a signal based on the switching operation of the switching means. A controller controls an X-ray receiving cassette to be ON when the signal is received. Accordingly, the convenience of X-ray imaging can be improved when using the X-ray system.
