Abstract

Experimental data for planar imaging with positron emitters (pulse height, efficiency and spatial resolution) obtained with two matrices of 25 crystals (2×2×30 mm³ each) of YAP:Ce coupled with a position sensitive photomultiplier (Hamamatsu R2A86-06) have been reproduced with high accuracy using the EGS4 code. Extensive simulation provides a detailed description of the performance of this type of detector as a function of the matrix granularity, the geometry of the detector and detection threshold. We present the Monte Carlo simulation and the preliminary experimental results of a prototype planar imaging system made of two matrices, each one consisting of 400 (2×2×30 mm³) crystals of YAP:Ce
