Abstract
The invention comprises a segmented rolling floor apparatus and method of use thereof, such as for use in a charged particle cancer therapy system. The segmented rolling floor comprises a first spool and a second spool, attached to opposite ends of the rolling floor, which cooperatively wind and unwind the rolling floor. The segmented rolling floor circumferentially surrounds a nozzle system penetrating through an aperture in the segmented rolling floor, where the nozzle system is used to deliver charged particles, from an accelerator, to a tumor of a patient. The rolling floor and nozzle systems move at respective rates maintaining the nozzle system in the aperture allowing for a safe/walkable floor while allowing treatment of the tumor as a gantry rotates the nozzle system and delivers protons to the tumor from positions above and below the floor.
