Spatially-Variant Image-Based Modeling of PSF Deformations with Application to a Limited Angle Geometry from a Dual-Panel Breast-PET Imager
Dual-panel PET system configuration can lead to spatially variable point-spread functions (PSF) of considerable deformations due to depth-of-interaction effects and limited angular coverage. If not modelled properly, these effects result in decreased and inconsistent recovery of lesion activity acro...
