US 2016/0250503 A1 · TREATMENT DELIVERY CONTROL SYSTEM AND METHOD OF OPERATION THEREOF

Abstract

The invention relates to a method and apparatus for control of a charged particle cancer therapy system. A treatment delivery control system is used to directly control multiple subsystems of the cancer therapy system without direct communication between selected subsystems, which enhances safety, simplifies quality assurance and quality control, and facilitates programming. For example, the treatment delivery control system directly controls one or more of: an imaging system, a positioning system, an injection system, a radio-frequency quadrupole system, a ring accelerator or synchrotron, an extraction system, a beam line, an irradiation nozzle, a gantry, a display system, a targeting system, and a verification system. Generally, the control system integrates subsystems and/or integrates output of one or more of the above described cancer therapy system elements with inputs of one or more of the above described cancer therapy system elements.

A method for extracting a circulating charged particle beam from a synchrotron, comprising the steps of:

circulating the circulating charged particle beam about a center of said synchrotron, said synchrotron comprising a circulating beam pathlength, said circulating charged particle beam comprising a time period of circulation;
applying a radio-frequency across a first pair of blades to alter a circulating path of the circulating charged particle beam, said radio-frequency comprising a frequency time period;
said step of applying the radio-frequency inducing a particle beam undergoing a betatron oscillation, the betatron oscillation sufficient for the charged particle beam to strike an extraction material;
transmitting the particle beam undergoing betatron oscillation and striking said extraction material through said extraction material, said extraction material yielding a reduced energy charged particle beam;
passing the reduced energy charged particle beam passing between a second pair of blades;
applying at least five hundred volts across said second pair of blades, wherein said second pair of blades redirects the reduced energy charged particle beam to a deflector and out of said synchrotron yielding an extracted charged particle beam.
