Counter balanced / cantilevered charged particle cancer therapy gantry system and method of use thereof

摘要: The invention comprises a method and apparatus for directing positively charged particles, comprising the steps of: (1) particles along beamline; (2) rotating cantilevered rotatable gantry arm, both connected to support supporting beamline, about horizontal rotation axis of support; (3) countering torque, at least using counterweight support. Optionally, movement is used as part arm three hundred sixty degrees around an inner side motion defined volume, which allows access one treatment room arc swept such entrance, mounting patient positioning system, and/or ground based structure.
