| 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.
