Summary: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-rays with an energy of 511 keV over the entire area of the scintillation plate was 1.76 mm. The proposed algorithm for calculating the determination accuracy of the interaction point can be used in positron-emission tomography.
