Event-by-event respiratory motion correction for PET with 3D internal-1D external motion correlation

Purpose: Respiratory motion during PET/CT imaging can cause substantial image blurring and underestimation of tracer concentration for both static and dynamic studies. In this study, the authors developed an event-by-event respiratory motion correction method that used three-dimensional internal-one...
