METHODS AND SYSTEMS FOR AXIALLY SEGMENTING POSITRON EMISSION TOMOGRAPHY DATA

摘要

A method for generating a Positron Emission Tomography (PET) image includes defining a scan window having a predetermined length along an examination axis of a PET imaging system the scan window corresponding to a region of interest to be continuously scanned by the PET imaging system defining at least two data bins corresponding to two separate scan regions within the scan window defining a transition region that overlaps a portion of each of the separate scan regions within the scan window the transition region having a width that is shorter than a length of the scan window binning emission data acquired within the transition region into the two data bins binning emission data acquired from outside the transition region into one of the two data bins and reconstructing an image using the emission data in the two data bins.
