Paper Abstract

Needs of improved medical diagnostics, specially for early and reliable breast cancer detection, lead us to consider developments in scintillation crystals and position sensitive photomultiplier tubes (PSPMT) in order to develop a high resolution medium field g-ray imaging device. However, gamma rays detector need to find a compromise between many conflicting requirements. In order to optimize different parameters involved in the detection process, we have developed a Monte Carlo simulation software. Its aims were to optimize a gamma ray imaging system based on pixellated scintillation crystal coupled to a PSPMT array. Several crystal properties were taken into account as well as the measured intrinsic response of PSPMTs. Images obtained by simulations are compared with experimental results. Agreement between simulation and experimental results validate our simulation model.
