Outline of Final Research Achievements

The aim of this study is to develop elemental technologies for treatment planning system applicable to every type of radiotherapy. In the study, we utilized “Tsukuba-Plan” which employs a multi-modal Monte Carlo code; PHITS. The PHITS allows implementing behaviors for every radiation. We created PHITS calculation definitions for several radiotherapy devices installed in University of Tsukuba Hospital as X-ray treatment device, proton therapy and BNCT. For carbon therapy, we made a definition for experimental port of NIRS. The definitions were installed in Tsukuba-Plan. And several phantom experiments performed in each facility were simulated with the Tsukuba-Plan. In verification, the calculation results determined by the Tsukuba-Plan were compared with the experimental values, respectively. The calculations were in good agreement with the experimental values. The results demonstrated that the Tsukuba-Plan allows performing dose estimations for several radiotherapies.
