[ 1 ] - Development and implementation of a Monte Carlo frame work for evaluation of patient specific out- of - field organ equivalent dose
Background: The aim of this study was to develop and implement a Monte Carlo framework for evaluation of patient specific out-of-field organ equivalent dose (OED). Materials and Methods: Dose calculations were performed using a Monte Carlo-based model of Oncor linac and tomographic phantoms. Monte Carlo simulations were performed using EGSnrc user codes. Dose measurements were performed using r...
[ 2 ] - Estimation of the thyroid secondary cancer risk on the patient of standard breast external beam radiotherapy
Introduction: The purpose of this study was to estimate the secondary cancer risk of thyroid for standard radiotherapy methods which are commonly used for breast cancer patients. Materials and Methods: Sixty-four breast cancer patients (their age range was around 50 years old) who referred to Seyed- Al- Shohada hospital (Isfahan, Iran) were included in this ...
[ 3 ] - Measurement Of Scatter Factors For Small Photon Fields Using Gaf chromic EBT2 Film
Introduction: Small field dosimetry is challenging for radiotherapy dosimetry. measurement of the output factor in the air and water (Sc, Scp) is one of the input parameters for commissioning of treatment planning systems and beam modeling. The aims of this study are to measured Sc,Scp for small fields with EBT2 and Ion chamber and design a appropriate mini-phantom for small fi...
