Abstract
The invention relates generally to treatment of solid cancers. More particularly, the invention relates to a multi-field imaging and/or a multi-field charged particle cancer therapy method and apparatus coordinated with patient respiration via use of feedback sensors used to monitor and/or control patient respiration. Preferably, the multi-field imaging, such as X-ray imaging, and the charged particle therapy are performed on a patient in a partially immobilized and repositionable position. X-ray and/or proton delivery is timed to patient respiration via control of charged particle beam injection, acceleration, extraction, and/or targeting methods and apparatus.
