Abstract
A fluoroscopic table having an electrically operated motor for moving the heavy fluoroscopic staging in a direction longitudinally of the table, the motor being controlled by a drive circuit which produces a constant output torque at the motor shaft which is of a predetermined value slightly less than the effort necessary to automatically initiate motion of the staging whereby an operator may apply only a slight amount of effort to cause such motion and will retain a natural 'feel' of control.
