| Research Abstract |
The purpose of this study was to establish the procedure for evaluating/improving the delivery precision using a new proton therapy system. Firstly, we investigated the radiologic behavior of proton beam by use of Monte Carlo simulation. Secondly, we evaluated several detectors for measuring the radiation dose from proton beam. As results, we estimated that the energy-loss of proton beam was happened at the irradiation-port of proton therapy system. Furthermore, we particularly made sure the characteristics of radiosensitive polymer gel dosimeter and radiochromic films. In conclusion, these tools are useful for proton beam dosimetry.
