ABSTRACT:
Methods and systems for providing scatter correction in a positron emission tomography (PET) system are provided. The method includes determining a look-up table of scatter sinograms during a PET acquisition scan period. The method further includes scatter correcting acquired scan data obtained during the PET acquisition scan period.
