Abstract

Methods and system for facilitating rapid radiation treatments are provided herein and relate in particular to radiation generation and delivery, beam control, treatment planning, imaging and dose verification. 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.
