Initial study of 3D dose verification of multi-field proton therapy treatment along match line with polymer gel detectors

Abstract

This paper is intended as an initial study for quality assurance benefits from polymer gel detectors to proton therapy treatments. Several gel types were explored for stability from batch to batch. The depth dose distributions in the gels were examined with regard to dose dependences and compared to baseline measurements. The results indicate polymer gel detectors may be able to verify dose in three dimensions along match line for proton therapy treatments
