Abstract

The University of Tsukuba is developing not only a linac-based neutron source for BNCT (iBNCT) but also a multi-modal treatment planning system (Tsukuba-Plan) for BNCT. We are currently performing several verifications. Phantom experiments performed in iBNCT were simulated by the Tsukuba-Plan, and the calculation results were compared with the measurements from the experiments. The calculations were in good agreement with the measurements. The results demonstrated that the Tsukuba-Plan can perform to estimate doses properly for BNCT treatment at iBNCT.
