SIMPLIFIED MODEL OF SCINTILLATION PULSE, AND RECONSTRUCTION AND ENERGY ACQUISITION METHOD THEREFOR

WIPO Patent Application WO/2018/049962

A1

Disclosed is a simplified model construction method for a scintillation pulse, comprising the following steps: in the process of using an original scintillation pulse model (I) to reconstruct a scintillation pulse signal obtained through practical sampling, for scintillation pulses of different energies, defining a practical start moment t0 of a scintillation pulse, a pulse rise time related parameter b and a pulse fall time related parameter d not changing and only a pulse amplitude a changing; and during the reconstruction of the scintillation pulse, regarding a moment of a pulse sampling value as a moment 0, and then constructing a simplified model of the scintillation pulse to be (II), wherein t'0, b0 and d0 are respectively empirical values of t0, b and d in the original scintillation pulse model. Also comprised are a scintillation pulse reconstruction method and a rapid energy information acquisition method, which can effectively reduce the complexity of the reconstruction of a scintillation pulse and accelerate the speed of the reconstruction of the scintillation pulse and that of the acquisition of energy information, and can also reduce the deterioration of a system energy resolution ratio as much as possible.
