Patent ID: 7642518

Claim:
A method of stabilizing signals generated by a scintillation detector that measures radiation, wherein the signals are dependent on an operating temperature of the detector, comprising: absorbing the radiation at least in part within the detector; determining, at least in part within the detector, a temperature-dependent calibration factor based on a shape of signals generated by the absorbed radiation; generating an output signal corresponding to an energy level of the absorbed radiation by receiving light at the detector, measuring a decay time of the signals generated by the absorbed radiation corresponding to the received light, and providing a signal corresponding to the measured decay time, all at least in part within the detector; determining a pulse form parameter by evaluating a shape of the output signal, at least in part within the detector; and applying the calibration factor to the output signal according to a ratio with respect to the pulse form parameter in order to stabilize the output signal, at least in part within the detector.
