Abstract
A nuclear imaging system () includes a crystal identification system () which receives a flood image () which includes a plurality of peaks, each peak responsive to radiation detected by a corresponding scintillator crystal. A crystal identification processor () partitions the flood image () into a plurality of regions (), each region being masked to correspond to one of an array of nuclear detectors. A model image () is generated in which the at least one Gaussian models represents the identified peaks. Misidentified peaks in the model image () in which locations of the peaks in the flood image () differ from the corresponding scintillator crystal are determined and the locations of the misidentified peaks in the flood image () are corrected. A calibration processor () corrects geometric distortions in acquired projection data according to the corrected peaks.
