RADIOACTIVE BEAM PROJECT AT HIMAC

摘要

Heavy-ion radiotherapy gives a good localized dose distribution just on a cancer tumor. In order to emphasize this advantage, the verification system of a particle range and an irradiated area in a human body has been developed for the Heavy Ion Medical Accelerator in Chiba (HIMAC) at National Institute of Radiological Sciences (NIRS). The idea comes from the fact that the stopping position of a short-lived positron emitting nuclei, such as ~(11)C, ~(15)O or ~(19)Ne, can be precisely detected by measuring annihilation gamma-rays.
