Multi-field cancer therapy apparatus and method of use thereof
First Claim
1. A method for positioning a tumor of a patient relative to positively charged particles, comprising the steps of:
- accelerating the positively charged particles with an accelerator;
guiding the positively charged particles from said accelerator to the tumor using a beamline of guiding magnets, said beamline comprising a rotatable magnet;
supporting the patient on a first rotatable platform; and
co-rotating said first rotatable platform and said rotatable magnet.

Abstract
A multi-field cancer therapy apparatus and method of use thereof is described increasing dimensionality of incident tumor treatment angles while minimizing distance between a final beamline focusing magnet and the patient. Increased dimensionality of incident tumor treatment angles is achieved through coordinated use of one or more of: a rotatable targeting magnet; a first patient rotation platform rotating the patient around, without intersecting, a vertical axis; a second patient rotation platform rotating a body part through a movable vertical axis; and patient tilt. The increased charged particle incident angle dimensionality distributes Bragg peak tail energy about the tumor. Dynamic energy and/or intensity control of the charged particle beam as a function of efficiency of beam delivery based on tumor shape further reduces Bragg peak tail energy delivered to healthy tissue about the tumor.
