Abstract

We describe a unified probabilistic graphical model for joint reconstruction of the activity and of the coordinates of the events of interaction in Emission Imaging. This new formulation is a discrete-discrete alternative to the discrete-continuous List Mode Likelihood model described by Barrett et al. The discrete-discrete formulation allows us to account for non-homogeneous resolution of the gamma-camera while adopting computationally efficient shift-invariant projection and back-projection algorithms. We describe an application of the model for the compensation of disrupted photo-detectors is SPECT.
