Zusammenfassung:The main purpose of this study is to participate in 3D Phantom simulations through the Geant4 code, after studying the effect of signal count rate gains, which is provides an improvement in the quality of the image construction. The results show that, low-noise estimates that random coincidences improve Signal-to-Noise Ratio (SNR) of sinograms and images with 17%.
