Abstract :
Time Of Flight PET is a promising technique that can improve the image quality of a PET scanner. A TOF PET detector must be designed by optimizing its energy and time resolution. Present study aims to assess the overall performances of a detector composed by LSO:Ce,Ca crystal coupled with SiPM, connected to a transimpedence amplifier. Simulation and measurements have been performed focusing on the influence of the Ca codoping concentration in the detector energy and time resolution.
