Study of silicon photomultipliers for the medical imaging systems

Novel photodetectors Silicon Photomultipliers (SiPMs) in combination with scintillation materials as LySO give an impressive progress in the development of the new generation Medical Imaging Systems. The experimental study of the detection system based on highly granular LySO crystals and SiPM is presented in the geometrical configuration of Positron Emission Tomography (PET) systems. An energy resolution of (7.68±0.15)% and a time resolution of (806±26) ps are measured. The experimental results are implemented in the GATE mathematical model of PET system equipped with LySO/SiPM detection block.
