  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.
