We have used the EGS4 Monte Carlo cede 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 (2x2x30 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 reconstructed volume was 2x2x2 cm3, the same of the reference mouse brain. The Monte Carlo results show that a spatial resolution below 2 mm (FWHM) can be obtained over the 2x2x2 cm3 volume with a sensitivity of about 600 counts/(jiCi's) for a gantry diameter of 15 cm, and a threshold of 50 keV. © 1999 IEEE.
