Abstract:
Interference of dose application in scanned ion beam therapy and organ motion, also called interplay effect, may lead to dose deviations at target volumes. Current repainting methods are susceptible to artifacts due to a predominant scanning direction, ranging from fringed field edges to under and overdosed regions (hot and cold spots). To overcome the difficulties inherent in the repainting techniques of conventional proton therapy systems, new random repainting techniques are described herein for mitigating the under-dose and/or over-dose pattern inherent in existing repainting techniques using a random repainting approach that randomly selects spot locations within the target area.

Claim (Index 11):
A radiation application system, comprising:\n a particle accelerator configured to produce a plurality of particles; a gantry coupled to the particle accelerator and configured to rotate around a target; a treatment nozzle coupled to the particle accelerator and configured to emit the plurality of particles as a directed beam at a target in the target; and a computing device coupled to the gantry and to the treatment nozzle and comprising:\n a memory device configured to store a target radiation plan comprising a timed sequence for irradiating the target with a first plurality of applications of the directed beam of the particles; and \n a processor configured to access the target radiation plan, to control rotation of the gantry, and to control the treatment nozzle, to paint the target with the first plurality of applications of the directed beam of the particles according to the target radiation plan and, subsequent to painting the target with the first plurality of applications of the directed beam of the particle, to repaint a first pattern of spot locations of the target with a second plurality of applications of the directed beam of the particles, wherein the first pattern of spot locations is selected at random.
