Abstract
A patient support device of a radiation therapy treatment system includes an electromechanical motor and control system for moving the support device. The control system utilizes regenerative braking concepts, converting the motor into a generator as the support device is moved such that no matter the load, the support device will be moved at a constant speed. The control system also allows for moving of the support device in the powered off situation (i.e., when there is no power to the support device).
