METHODS AND SYSTEMS FOR RF POWER GENERATION AND DISTRIBUTION TO FACILITATE RAPID RADIATION THERAPIES

摘要

Methods and system for facilitating rapid radiation treatments are provided herein and relate in particular to radiation generation and delivery, power production and distribution, and electron source design. The methods and systems described herein are particularly advantageous when used with a compact high-gradient, very high energy electron (VHEE) accelerator and delivery system (and related processes) capable of treating patients from multiple beam directions with great speed, using all-electromagnetic or radiofrequency deflection steering is provided, that can deliver an entire dose or fraction of high-dose radiation therapy sufficiently fast to freeze physiologic motion, yet with a better degree of dose conformity or sculpting than conventional photon therapy.

1. A power distribution system for powering multiple accelerators, the system comprising:
a plurality of RF power sources; a plurality of accelerating structures; an RF phase array coupling the plurality of RF power sources with the plurality of accelerating structures; and a programmable controller operatively coupled with the RF phase array to control a phase and an amplitude of the RF phase array such that a total RF energy from the plurality of RF power sources is directed to a select accelerating structure of the plurality through source phasing.
