Automatic retractable floor system for a rotating gantry
First Claim
1. A floor system for use with a rotating gantry in a radiation treatment facility comprising:
- a carriage assembly configured to be slidably supported within the gantry to maintain a substantially constant orientation while the gantry is rotating; and
an extendable/retractable panel assembly supported on said carriage assembly, said panel assembly including a plurality of non-movable floor panels and a like plurality of movable floor panels slidably mounted over corresponding ones of said non-movable panels to extend outside said carriage assembly, said movable panels sized to span a distance between said carriage assembly and a fixed floor of the treatment room and each of said movable panels having a platform surface for supporting a person thereon.

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.
