英文摘要
A purpose of this study is to develop a gamma camera system for reconstruction of irradiation position and delivered absorbed dose distribution using information of the Compton scattered photons from a patient during radiation therapy with high energy x-rays.For this purpose the idea of Compton camera was taken in and the possibility was demonstrated by the simulation. Furthermore to design a prototype system, the energy spectrum and accumulation efficiency of the Compton scattered photons was simulated and confirmed experimentally. Using these data, the basic study related a detector, a collimator system and reconstruction algorithm was performed.
