Evaluation of target dose inhomogeneity in breast cancer treatment due to tissue elemental differences

Radiation Oncology, 2018
Background Monte Carlo simulations were run to estimate the dose variations generated by thedifference arising from the chemical composition of the tissues. Methods CT datasets of five breast cancer patients were selected. Mammary gland was delineated as
