ABSTRACT:
A radiographic fluoroscopic X-ray table including a rigid fluoroscopic staging apparatus where the spot film device is synchronized along the transverse axis with the X-ray tube by means of a telescoping shaft assembly. The telescoping shaft assembly engages a rack in the spot film device and drives a sprocket and chain system connected to the X-ray tube and collimator. The telescoping shaft also increases and decreases its length to accomodate the spot film device being moved up and down in the vertical direction above the table. The spot film device and the fluoroscopic staging aparatus are counterbalanced in the vertical direction and along the table's longitudinal axis through a system of pulleys, cables and counterweights. A power assist system is provided to drive the staging apparatus along the longitudinal axis of the X-ray table.
