By simulating the detection procedure of 511 keV γ photons in the scintillating detector which consists of a bulk NaI(Tl) scintillation crystal
a glass light guide and a PMT array
a novel neural network estimator is applied to calculate the incidence point of γ photons corresponding to the output scintillating light from PMT array.Compared with traditional Anger algorithm
neural network can conquer or reduce the interaction-depth effect and edge effect
and give high spatial resolution.Meanwhile from the point of view of practical application
relationship between the generalization ability of neural network and the incidence angle is also studied in the paper.
