The Monte Carlo simulation of small animal conventional positron emission tomography (PET) is an important tool for geometry parameters optimization, image reconstruction algorithm tests, performance of different radioisotopic sources and some others. The present work deals with the Monte Carlo study of a small cylindrical PET system in the framework of the GEANT4 code. Two different accepted ring width values and spherical sources of {sup 18}F and {sup 44}Sc isotopes were considered. Then, the improvement of the detection efficiency and spatial resolution was analyzed in all the cases.
