Monte Carlo Simulation of a Linear Accelerator and Electron Beam Parameters Used in Radiotherapy
Introduction: In recent decades, several Monte Carlo codes have been introduced for research and medical applications. These methods provide both accurate and detailed calculation of particle transport from linear accelerators. The main drawback of Monte Carlo techniques is the extremely long computing time that is required in order to obtain a dose distribution with good statistical accuracy. ...

متن کاملComparison of Electron-Beam Dose Distributions in a Heterogeneous Phantom Obtained Using Radiochromic Film Dosimetry and Monte Carlo Simulation
Introduction: Nowadays new radiochromic films have an essential role in radiotherapy dosimetry. Properties such as high sensitivity, good reproducibility, high spatial resolution, easy readout and portability have made them attractive for dosimetry, especially in high-dose-gradient regions. Material and Methods: In this study, electron-beam dose distributions in homogenous and heterogeneous pha...
متن کاملA Monte Carlo Simulation of Photon Beam Generated by a Linear Accelerator
ntroduction: Monte Carlo simulation is the most accurate method of simulating radiation transport and predicting doses at different points of interest in radiotherapy. A great advantage of the Monte Carlo method compared to the deterministic methods is the ability to deal accurately with any complex geometry. Its disadvantage is the extremely long computing time r...
متن کاملMonte Carlo estimation of electron contamination in a 18 MV clinical photon beam
Background: The electron contamination may reduce or even diminish the skin sparing property of the megavoltage beam. The detailed characteristics of contaminant electrons are presented for different field sizes and cases. Materials and Methods: The Monte Carlo code, MCNPX, has been used to simulate 18 MV photon beam from a Varian Linac-2300 accelerator. All dose measurements were car...
