Abstract
A system and method of reducing pile-up errors in multi-crystal tomography applications. In a system with multi-crystal gamma ray detectors having scintillating crystals with different decay constants, the problem of signal pile-up is avoided by taking energy samples during a fast integration time and stopping the integration process if the sampling indicates that the event occurred in the crystal with the faster decay time, and continuing the integration process if the sampling indicates that the event occurred in the crystal with the slower decay time.
