Evaluation of respiratory and cardiac motion correction schemes in dual gated PET/CT cardiac imaging

Purpose: Cardiac imaging suffers from both respiratory and cardiac motion. One of the proposed solutions involves double gated acquisitions. Although such an approach may lead to both respiratory and cardiac motion compensation there are issues associated with (a) the combination of data from cardia...
