Abstract:
1. A method, comprising: detecting optical outputs generated by a plurality of scintillation crystals of a detector with an array of pixelated detectors; generating, with the array of pixelated detectors, respective signals indicative of the optical outputs; generating, from the respective signals, a unique energy spectrum correlated to each of the plurality of scintillation crystals; grouping subsets of the plurality of scintillation crystals into macrocrystals; determining a representative energy spectrum peak for each macrocrystal based on the respective energy spectra of the scintillation crystals in the macrocrystal; comparing a value of the representative energy spectrum peak for each macrocrystal with a target peak value; and adjusting an operating parameter of at least one pixelated detector in the array of pixelated detectors as a result of the comparison.
