Patent ID: 8642978

Claim:
A method for irradiating a tumor of a patient with charged particles, comprising the steps of: delivering the charged particles with a charged particle therapy system, comprising: a synchrotron; a charged particle beam path; and a rotatable platform, wherein said charged particle beam path runs through said synchrotron and runs above said rotatable platform; during an irradiation period, rotating said rotatable platform to at least five irradiation positions covering at least ninety degrees of rotation of said rotatable platform; irradiating the tumor with the charged particles during each of said at least five irradiation positions; rotating said rotatable platform through about three hundred sixty degrees during said irradiation period, wherein said charged particle therapy system further comprises an irradiation control module, wherein the tumor comprises a distal region, wherein said irradiation control module further comprises the steps of: terminating said charged particle beam path in said distal region of the tumor, using control of energy of the charged particles, in each of said at least five irradiation positions; and said irradiation control module controlling both rotation of said rotatable platform and said energy of the charged particles to irradiate, with Bragg peak energy of the charged particles, a changing distal position of the tumor as a function of position of said rotatable platform.
