ABSTRACT:
A movable floor system for use with a rotating gantry in a radiation treatment facility is provided that comprises a carriage assembly slidably supported within the gantry to maintain a substantially constant orientation while the gantry is rotating. An extendable/retractable panel assembly is supported on the carriage assembly that includes a plurality of non-movable floor panels and a like plurality of movable floor panels slidably mounted over corresponding ones of the non-movable panels. The movable panels are sized to span a distance between the carriage assembly and a fixed floor of the treatment room. Each of the movable panels has a platform surface for supporting a person for access to and from the patient table situated within the gantry. A control system coordinates the extension and retraction of the movable floor panels to prevent collisions with the radiation nozzle as it rotates during the patient treatment.
