RECONSTRUCTING IMAGES FOR A WHOLE BODY POSITRON EMISSION TOMOGRAPY (PET) SCAN WITH OVERLAP AND VARYING EXPOSURE TIME FOR INDIVIDUAL BED POSITIONS

摘要

A non-transitory computer-readable medium stores instructions readable and executable by a workstation (18) including at least one electronic processor (20) to perform an image reconstruction method (100). The method includes: operating a positron emission tomography (PET) imaging device (12) to acquire imaging data on a frame by frame basis for frames along an axial direction with neighboring frames overlapping along the axial direction wherein the frames include a frame (k), a preceding frame (k−1) overlapping the frame (k), and a succeeding frame (k+1) overlapping the frame (k); reconstructing an image of the frame (k) using imaging data from the frame (k), the preceding frame (k−1), and the succeeding frame (k+1).
