Noise study in Monte Carlo estimated system matrix for OPET

Abstract

The traditional method for estimating system matrices consists of simulating a number of annihilation events at each voxel position such that some error measured is minimized. However, axial sensitivity decreases as we move away from the center of the FOV and the number of detected coincidences is substantially smaller at the edge of the scanner than at the… (More)
