Monte Carlo simulation of average glandular dose and an investigation of influencing factors.

This study aims to determine the average absorbed dose of radiation in glandular tissue during mammography and to investigate factors that influence the average glandular dose, particularly the local distribution of glandular tissue within the breast and breast skin thickness. An EGSnrc Monte Carlo code and associated codes were employed in the simulation. The breast voxel models used consist o...

Evaluation of glandular dose in mammography in the presence of breast cyst using Monte Carlo simulation

Introduction: Average glandular dose (AGD), entrance skin air kerma (ESAK) and normalized glandular dose (DgN) are the main dosimetric quantities in mammography. In this study, DgN is evaluated in the presence of breast cyst, which is a common disease among women and the influence of size, number and location of the cysts on the DgN is investigated. Materials and Meth...

Investigation and Comparison of Metal Nanoparticles on Dose Enhancement Effect in Radiotherapy Using Monte Carlo Simulation Method

Introduction: The main goal of radiation therapy is destroying the tumor so that the surrounded healthy tissues have received the least amount of radiation at the same time. In recent years, the use of nanoparticles has received much attention due to the increasing effects they can have on the deposited dose into the cancer cells. The aim of this study was to investigate the effects of nanopart...

Megavoltage dose enhancement of gold nanoparticles for different geometric set-ups: Measurements and Monte Carlo simulation

Background: Gold nanoparticles (GNPs) have been shown as a good radiosensitizer. In combination with radiotherapy, several studies with orthovoltage X-rays have shown considerable dose enhancement effects. This paper reports the dose enhancement factor (DEF) due to GNPs in 18 megavoltage (MV) beams. Materials and Methods: Different geometrical 50-nm GNPs configurations at a concentrati...
