| Research Abstract |
To perform in-vivo dosimetry in the proton beam therapy, I developed a dose calculation algorithm which can calculate precisely even in tissue heterogeneity. I tried the use of the metal oxide-silicon semiconductor field effect transistor (MOSFET) detector as a radiation detector for in-vivo dosimetry and improved sensitivity deterioration of the MOSFET detector for linear energy transfer (LET) effects. Furthermore, a correction method for sensitivity deterioration of the MOSFET detector was developed, and the proton dose measurements with the MOSFET detector by the correction method was established.
