摘要：
The invention comprises a method and apparatus for directing charged particles into a patient from several directions. A delivery system is described that uses a primary beam line from an accelerator to a path switching magnet used to dynamically direct bunches of the positively charged particles down a selected pathway of a plurality of physically separated beam transport lines to a single patient treatment position, where the selected pathways enter the patient from two or more sides. Optionally, a repositionable treatment nozzle is repositioned to interface with each beam transport line, which allows the charged particle delivery system to use a single scanning capable nozzle in combination with delivery of the charged particles to the two or more sides of the patient to implement a tumor irradiation plan without a necessity of a moveable beamline in, at, or near a treatment room.
