Outline of Final Research Achievements

The purpose of this study is to develop suitable technique of respiratory gating spot scanning proton therapy (RG-SSPT). In this research term, we have carried out 3 contents: Monte Carlo simulation for RG-SSPT, development of respiratory management system by monitoring patient body surface, development of in-house program for independent dose verification system for RG-SSPT. As results, RG-SSPT hardly produced scattered radiation in system unit. Due to patient surface observation and analysis, we estimated suitable monitoring region for RG-SSPT. Then we could analyze respiratory signal continuously. With in-house independent dose verification program, we could estimate/verify dose distribution of RG-SSPT.
