ABSTRACT:
A videofluoroscopy device having a vertical housing and a c-arm supporting an x-ray device is provided. The vertical housing encloses a first channel wherein a center screw is mounted. The center screw engages a mounting block having a threaded aperture formed therein, the mounting block being attached to the c-arm. A motor engaging the center screw turns the center screw in reversible directions thereby causing the center screw to communicate with the c-arm and moving the c-arm along a longitudinal axis to record a real time video x-ray image of a patient. A video monitor and video tape recorder are connected to the x-ray device by a video cable.
