A GEANT4 based Simulation for Pixelated X-ray Hybrid Detectors: Extended   Report
  Monte Carlo simulations are powerful tools for understanding the effects of radiation interactions within detector devices allowing not only to evaluate typical estimates for experimental measurements and to serve as means for designing experiments but to provide additional information that are usually not easily accessible experimentally. A simple numerical approach to describe the functioning of pixelated detectors is presented in this paper. Estimates from a variety of simulated setups are obtained and the observed features compared with experimental results to verify to which extent they are correctly described by this method. Fundamental curves such as interaction probability and reconstructed energy deposited are calculated as function of beam energy. Pixel response, charge sharing effects and resolution estimates are also obtained.
