CHARGED PARTICLE CANCER THERAPY DOSE DISTRIBUTION METHOD AND APPARATUS
First Claim
1. An apparatus for irradiating a tumor of a patient with charged particles, comprising:
- 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 above a portion of said rotatable platform;
wherein said rotatable platform rotates at least ninety degrees during an irradiation period,wherein said rotatable platform rotates to at least five irradiation positions during said irradiation period.

Abstract
The invention relates generally to treatment of solid cancers. More particularly, a method and apparatus for efficient radiation dose delivery to a tumor is described. Preferably, radiation is delivered through an entry point into the tumor and Bragg peak energy is targeted to a distal or far side of the tumor from an ingress point. Delivering Bragg peak energy to the distal side of the tumor from the ingress point is repeated from multiple rotational directions. Beam intensity is proportional to radiation dose delivery efficiency. The multi-field irradiation process with energy levels targeting the far side of the tumor from each irradiation direction provides even and efficient charged particle radiation dose delivery to the tumor. Preferably, the charged particle therapy is timed to patient respiration via control of charged particle beam injection, acceleration, extraction, and/or targeting methods and apparatus.
