Outline of Final Research Achievements

In this study, a Monte Carlo simulation system for carbon-ion therapy was developed. The PTSIM was employed for this purpose and modified to calculate biological dose distributions. For validation of the PTSIM, the simulation should be verified by comparing the simulation results with the experimental data. Tuning certain parameters such as fluctuation factors of initial beam energies should be considered as well. The calculated residual ranges or depth dose distributions are compatible with the measurements within small differences. Although some issues persist, the system is a prospective tool for carbon-ion therapy and is expected to offer important and useful information.
