Abstract
The invention relates generally to treatment of solid cancers. More particularly, the invention relates to a multi-field charged particle cancer therapy method and apparatus coordinated with negative ion beam creation, ion beam focusing, charged particle acceleration, patient rotation, and/or patient respiration. Preferably, the charged particle therapy is performed on a patient in a partially immobilized and repositionable position. Proton delivery is preferably timed to patient respiration via control of charged particle beam injection, acceleration, and/or targeting methods and apparatus.
Claims15
A particle beam irradiation apparatus for charged particle cancer therapy of a tumor of a patient, comprising:
- a synchrotron accelerating a charged particle beam;
- a respiration sensor generating a respiration signal, said respiration signal monitoring a breathing cycle of the patient;
- a rotatable platform holding the patient,
- wherein said rotatable platform rotates through about three hundred sixty degrees during an irradiation period of the patient,
- wherein said synchrotron uses said respiration signal to deliver said charged particle beam to the tumor at a set point in said breathing cycle,
- wherein said delivery of said charged particle beam at said set point of said breathing cycle occurs in greater than five rotation positions of said rotatable platform.
