Abstract
A method for correcting a positron emission tomography (PET) emission image is described. The method includes obtaining a PET emission sinogram of an object, obtaining a computed tomography (CT) image for a scanned portion of the object, the object having a truncated portion outside a field of view (FOV) of a CT image, determining a correction set of CT data based on a measured set of CT data within the CT sinogram, generating modified attenuation correction factors from the measured and correction sets of CT data, and correcting the PET sinogram using the modified attenuation correction factors.
