Simulation of gamma camera in Yeditepe university hospital with gate

The aim of this thesis is to have a detail simulation of Gamma Camera in Yeditepe University Hospital Nuclear Medicine Deapartment to carry the personal dosimetric calculations for all the patients before the treatment. In this thesis, Gamma Camera being used routinely in Yeditepe University Hospital Nuclear Mecidine Department was investigated experimentally and with Monte Carlo simulation. A new and open Monte Carlo Code source, GATE, was used that for simulations running commands in C++ language. First of all various crystals and activities were investigated with the simulations. Secondly, The performance experiments of Gamma Camera (made PHILIPS-forte) in Yeditepe University Hospital were done according to NEMA criteria and also at the same time the simulations were run. Finally, the experimental and simulation results were compared and the new results were all installed to the simulation in order to have the Yeditepe University Hospital Gamma Camera complete simulation.
