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 14):
A non-transitory computer readable medium comprising a plurality of programmed instructions that, when executed by a processor in a computing system, is operable to implement a target radiation plan using randomly distributed spot locations, the computer readable medium comprising:\n instructions to access the target radiation plan, wherein the target radiation plan comprises a temporal and spatial sequence for administering a target dosage to a target using a first plurality of applications of a directed beam of particles; instructions to paint the target with the first plurality of applications of the directed beam of particles according to the target radiation plan; and instructions to repaint, subsequent to painting the target with the first plurality of applications of the directed beam of particles, a first pattern of spot locations of the target with a second plurality of applications of the directed beam of particles, wherein the first pattern of spot locations is selected at random.
