| Outline of Final Research Achievements |
The purposes of this study were to establish the variable energy modulated proton therapy system and to verify the feasibility of the system. In this term of the research, we carried out several contents: Monte Carlo simulation for proton beam system, the dosimetric verification of respiratory-gated irradiation by use of various detectors, and development of monitor-unit calculation software. As the results, we estimated the energy-loss of passive proton beam with a broad beam method by use of range modulation wheel.at the point of interest. The delivery precision was feasible with the gating rate of over 25%. The developed our program could calculate the monitor unit of proton beam and the error was less than 2%.
