Using neural networks, spatial characteristics of the prototype module of the positron-emission tomograph (PET) based on scintillation crystalline plates LSO(Y) and a silicon photomultiplier array were calculated. The average spatial resolution of the Z-coordinate of the interaction point of gamma-r...
