Performance Evaluation of Amplitude and Phase Respiratory Gating Methods on Continuous-Bed-Motion Whole-Body PET Studies

Positron emission tomography (PET) scanners with the feature of continuous-bed-motion (CBM) that allows efficient whole-body dynamic scans and customized imaging protocols have been made commercially available in recent years. As the bed motion has to be reasonably slow in order to achieve sufficient count statistics, the blurring effect induced by respiratory motion is inevitable, and adequate ga...
