Computational exposure models can be used to estimate human body absorbed dose in a
series of situations such as X-Ray exams for diagnosis, accidents and medical treatments.
These models are fundamentally composed of an anthropomorphic simulator (phantom), an
algorithm that simulates a radioactive source and a Monte Carlo Code. The accuracy of data
obtained in the simulation is strongly connected to the adequacy of such simulation to the real
situation. The phantoms are one of the key factors for the researcher’s manipulation. They are
generally developed in supine position and its anatomy is patronized by compiled data from
international institutions such as ICRP or ICRU. Several pathologies modify the structure of
organs and body tissues. In order to measure how significant these alterations are, an
anthropomorphic model was developed for this study: patient mastectomies. This model was
developed using voxel phantom FASH and then coupled with EGSnrc Monte Carlo code.
