ABSTRACT:
Certain embodiments include a system and method for tilting in a patient positioning system. The system includes a tilt plate for tilting a patient positioning surface, a screw for moving the tilt plate, a nut for translating rotary motion into linear motion to drive the screw, and a motor for imparting rotary motion to the nut. In an embodiment, the screw is a ball screw. In an embodiment, the nut is a rotary nut. The system may also include a drive gear situated on the motor, a driven gear situated on the nut the meshes with the drive gear, and a brake gear that meshes with the driven gear. The system may also include a fail-safe brake preventing collapse of the tilt mechanism in the event of a component failure.
