Abstract
An automatic and intuitive calibration method is provided for calibrating a radiation detection system for processing counts from a known radiation source. A probe is positioned near the radiation source, which may be the surgical injection site of a radionucleide. A control unit generates audible and/or visual feedback signals to cue the operator as to where to position the probe relative to the radiation source, in order to obtain a pulse frequency (count rate) in an optimal range for processing. The control unit then automatically identifies a peak energy level and sets an energy acceptance window having a mathematical relationship to the peak energy level, whereby the radiation detection system thereinafter processes only counts corresponding to energy levels falling within the energy acceptance window.
