Mammography presents one of the most precise methods for detection of irregularities inside the breast. Its most important function is discovering diseases like cancer at an early phase. Although mammography uses a low dose x-ray system, the examination still poses certain risk for a patient. Mean glandular dose gives the best representation of risk involved for a patient undergoing mammography examination. In this study, we estimated adipose, glandular and total dose to the breast using Monte Carlo simulations. For this purpose, we designed a voxel breast phantom. Simulations were performed using MCNPX code. Verification of phantom design and simulations was done by comparing the results with those published in similar studies.
