MULTI-AXIS CHARGED PARTICLE CANCER THERAPY METHOD AND APPARATUS

摘要

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.
