Partial volume correction of doubly-gated cardiac datasets using anatomical and edge-preserving priors

Positron emission tomography (PET) images suffer from partial volume (PV) effects due to the poor spatial resolution of the PET system. In cardiac imaging, additional blurring is caused by the breathing motion and the beating of the heart. Dual gating of the cardiac datasets is one possible approach to remove the motion blur [1], but it dramatically reduces the statistics of the dataset and leads to extremely noisy reconstructions (still to be corrected for PV).
