Monte Carlo simulation for PET scanners and shields
Access this Article
A Monte Carlo simulation code was developed for simulating PET scanners with the Monte Carlo program package GEANT. The present simulation code can handle not only conventional types of PET scanners, but also any complex detector systems with arbitrary geometrical configuration. All the relevant interactions of photons and electrons are taken into account in all the defined objects while optical tracking in the scintillation crystals is approximated by simple analytical simulation.
