Clinical evaluation of PET image reconstruction using a spatial resolution model

Abstract Purpose PET image resolution is variable across the measured field-of-view and described by the point spread function (PSF). When accounting for the PSF during PET image reconstruction image resolution is improved and partial volume effects are reduced. Here, we evaluate the effect of PSF-b...
