Abstract

A Monte Carlo simulation code has been developed to predict new PET scanners´ performances, such as sensitivity and scatter fraction, or obtain physics information such as deposited energy spectra. The code has been tested on a CTI PET prototype based on LSO panel detectors, and its results are in excellent agreement with experimental data: in particular a comparison of Noise Equivalent Count Rate curves is presented. Coupling the accurate physics embedded in Monte Carlo simulation and a scanner modeling allowed us to obtain a reliable tool for PET scanners´ design.
