摘要：
A non-transitory computer-readable medium storing 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: receiving a surview image of a target anatomy acquired by an image acquisition device (12)； selecting an axial field of view (FOV) of an imaging volume using the received surview image； optimizing axial boundaries of leading and trailing frames respective to the selected axial FOV of the imaging volume； operating a positron emission tomography (PET) imaging device (14) to acquire PET imaging data including acquiring PET imaging data for the leading frame followed by acquiring PET imaging data for the imaging volume followed by acquiring PET imaging data for the trailing frame； and reconstructing the PET imaging data to generate an image of the selected imaging volume including out-of-axial FOV scatter correction performed using the PET imaging data acquired for at least one of the leading and trailing frames.
