Abstract
The invention comprises a multi-axis charged particle irradiation method and apparatus. The multi-axis controls includes separate or independent control of one or more of horizontal position, vertical position, energy control, and intensity control of the charged particle irradiation beam. Optionally, the charged particle beam is additionally controlled in terms of timing. Timing is coordinated with patient respiration and/or patient rotational positioning. Combined, the system allows multi-axis and multi-field charged particle irradiation of tumors yielding precise and accurate irradiation dosages to a tumor with distribution of harmful proximal distal energy about the tumor.
Claims9
An apparatus using positively charged particles for irradiation of a tumor of a patient, comprising:
- a beam path;
- an extraction foil in said beam path;
- a synchrotron comprising multi-axis control, said multi-axis control comprising control of:
- an energy, the energy controlled during use through timing of transmission of the positively charged particles through said extraction foil;
- and
- an intensity, the intensity controlled during use using a current originating from said extraction foil, wherein energy of the positively charged particles striking said extraction foil yields a secondary electron from said extraction foil to form the current;
- and
- a pair of extraction blades, said beam path passing between said pair of extraction blades,
- wherein said beam path sequentially passes through said synchrotron, said extraction foil, and said pair of extraction blades.
