We have used the EGS4 Monte Carlo code to simulate the performance of a Positron Emission Tomograph for small animals. The Tomograph is a four-head detector, made of matrices of 400 YAP:Ce finger-like crystals (2×2×30 mm3 each) coupled to Position Sensitive Photo-Multipliers Hamamatsu R2486-06. 3-D reconstruction algorithms have been applied to the 3-D simulated data. The Monte Carlo results show that a spatial resolution below 2 mm (FWHM) can be obtained over a field of view of 2×2×2 cm3 with a sensitivity of about 550 counts/(μCis) for a gantry diameter of 15 cm, and a threshold of 150 keV.

Abstract
We have used the EGS4 Monte Carlo code to simulate the performance of a Positron Emission Tomograph for small animals. The Tomograph is a four-head detector, made of matrices of 400 YAP:Ce finger-like crystals (2×2×30 mm3 each) coupled to Position Sensitive Photo-Multipliers Hamamatsu R2486-06. 3-D reconstruction algorithms have been applied to the 3-D simulated data. The Monte Carlo results show that a spatial resolution below 2 mm (FWHM) can be obtained over a field of view of 2×2×2 cm3 with a sensitivity of about 550 counts/(μCis) for a gantry diameter of 15 cm, and a threshold of 150 keV.File in questo prodotto:
