Abstract
Methods, systems, and machine-readable storage mediums for reconstructing a PET image are provided. In one aspect, a method includes: determining a plurality of LORs associated with multiple-coincidence data in coincidence data detected by a PET device through scanning, obtaining a respective line integral value along each of the LORs according to a time difference between two single events corresponding to the LOR, allocating the multiple-coincidence data to the LORs according to the respective line integral values of the LORs to obtain respective multiple allocation data on the LORs, correcting respective double-coincidence data in the coincidence data corresponding to each of the LORs based on the respective multiple allocation data on the LOR to obtain data of the LOR, and reconstructing an image according to the data of each of the LORs.
