Image reconstructions from super-sampled data sets with resolution modeling in PET imaging

PURPOSE: Spatial resolution in positron emission tomography (PET) is still a limiting factor in many imaging applications. To improve the spatial resolution for an existing scanner with fixed crystal sizes, mechanical movements such as scanner wobbling and object shifting have been considered for PE...
