| Research Abstract |
Since tumor is usually located deep inside the body, it is inevitable that normal tissues surrounding the tumor undergo unfavorable irradiation. To reduce such irradiation, several techniques have been adopted in charged particle therapy, such as (1) multi-port irradiation, (2) Selection of beam direction avoiding organ at risk and (3) fractionated irradiation. With regard to (1) and (2), an optimum combination of beam directions differs for each treatment and patient. The purpose of this study is to look for a fast and simplified algorithm with which a combination of irradiation directions can be optimized. It turned out that (1) to select the direction oppose to organ at risk and (2) to separate two irradiation directions as far as possible are effective to reduce irradiation normal tissue. An optimal choice of irradiation direction can be obtained in short computation time.
Part of this study has been summarized in a manuscript, and will be submitted to an European journal.
