Abstract:
1. A method for positioning a tumor of a patient for treatment with positively charged particles, comprising the steps of: positioning the patient with a patient positioning system, said patient positioning system comprising an upper body support, wherein said upper body support comprises a semi-upright patient support surface; after said step of positioning, collecting multi-field images of the tumor in the patient; developing a tumor irradiation plan; repositioning the tumor using said patient positioning system; after said step of repositioning, verifying position of the tumor; irradiating the tumor of the patient with the positively charged particles from a charged particle system, said charged particle system comprising a charged particle beam path, said charge particle beam path passing within about six inches of said semi-upright patient support surface; repeating said step of irradiating in at least four rotation positions; controlling an energy of the charged particle using an accelerator in said charged particle system, said accelerator comprising: using a radio-frequency synthesizer, sending a low voltage signal to each of said at least ten microcircuits, each of said at least ten microcircuits amplifying said low voltage signal yielding an acceleration voltage.
