Abstract
The Monte Carlo code PENELOPE (version 2014) and its software package PenEasy have been employed to closely simulate a commercial mammography system: Selenia Dimensions system (Hologic, Bedford, Mass) for dosimetric study. Normalized glandular dose (DgN) was derived for specific filter combinations including tungsten/aluminum (W/Al), tungsten/rhodium (W/Rh) and tungsten/silver (W/Ag) for a range of clinically used voltages (kV). Breast models with thickness 2 cm, 4.5 cm and 8 cm and respective glandularity 100 %, 50 % and 0.1 % were included in the simulations. Derived DgN values were in good agreement with well-accepted published values, with mean differences of 1.30 %, 2.17 % and 0.17 % for the W/Al, W/Rh and W/Ag anode/filter combinations, respectively. In the next phase of the study, this validated model will be modified to perform patient-specific dosimetry with an improved breast model and more realistic simulation of commercial mammography systems.
