Abstract

Purpose: In this paper, the effective atomic numbers (Z(eff)), electron densities (N-eff), exposure buildup factor (EBF) and energy absorption buildup factor (EABF) of healthy (H), carcinoma (C) and equivalent (E) breast tissues were investigated to quantify differences in radiological parameters between the tissues in the continuous energy region. For these purposes, Z(eff)s and N(eff)s, of healthy, carcinoma and equivalent (H-C-E) breast tissues were calculated for interaction of gamma rays and charged particles with selected tissues. EBFs and EABFs of the tissues were also calculated for gamma rays as well and were compared to each other for different photon energies (0.015-15 MeV) up to 40 mfp.
