Online Detector Response Calculations for High-Resolution PET Image Reconstruction

Positron emission tomography (PET) systems are best described by a linear shift-varying model. However, image reconstruction often assumes simplified shift-invariant models to the detriment of image quality and quantitative accuracy. We investigated a shift-varying model of the geometrical system re...
