Evaluation of a New Regularization Prior for 3-D PET Reconstruction Including PSF Modeling
Abstract
The response of a PET system can be described by its characteristic Point Spread Function (PSF) representing the spatial degradation of a point source due to physical effects and system design. If the PSF is accounted for in the reconstruction algorithm, better image quality and spatial resolution may be achieved. Unfortunately, a common behaviour of unregularized iterative reconstruction techniques is represented by the increase...
