Abstract
A method and apparatus to improve the measurement accuracy for ionizing radiation pulses when using large scintillator crystals that absorb their own scintillation light.
Claims16
A method for compensating for pulse shape variation of light generated by scintillator detectors comprising:
- a. receiving ionizing radiation pulses into a scintillator utilizing activated crystals that generate analog light pulses;
- b. converting the generated light pulses into analog electrical pulses;
- c. converting the analog electrical pulses into digital pulses;
- and
- d. processing the digital pulses to provide a measure of the energy y_e[n] received in the scintillator;
- e. wherein the step of processing the digital electrical pulses to provide a measure of the energy E received in the scintillator is computed from a predetermined number of y_e[n] values where y_e[n]=(y[n]−y_dc)*w[n], y_dc is a direct current baseline in the absence of a pulse, and w [n] is a supplied set of weighting coefficients.
