MLC parameters from static fields to VMAT plans: an evaluation in a RT-dedicated MC environment (PRIMO)

Radiation Oncology, 2019
Background PRIMO is a graphical environment based on PENELOPE Monte Carlo (MC) simulation of radiotherapy beams able to compute dose distribution in patients, from plans with different techniques. The dosimetric characteristics of an HD-120 MLC (Varian),

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
