Commissioning and validation of the Elekta One GPUMCD algorithm for an Elekta VersaHD linear accelerator. [PDF]

J Appl Clin Med Phys
Abstract Purpose The purpose of this work was to commission and validate GPUMCD, a GPU‐accelerated Monte Carlo dose calculation engine for c‐arm Elekta linear accelerators (linac). This algorithm was recently released for clinical implementation in the Elekta One Treatment Planning System (v6.2.3, EOP). Methods A GPUMCD beam model was generated for all

Comparison between EGSnrc, Geant4, MCNP5 and Penelope for mono-energetic electron beams

Physics in Medicine and Biology, 2015
A simple geometry is chosen to highlight similarities and differences of current electron transport algorithms implemented in four Monte Carlo codes commonly used in radiation physics. Energy deposited in a water-filled sphere by mono-energetic electron beams was calculated using EGSnrc, Geant4, MCNP5 and Penelope as the radius of the sphere varied ...

Development and validation of a TOPAS Monte Carlo model for a 0.5 T bi-planar Linac-MR. [PDF]

Med Phys
Abstract Background MR‐guided radiotherapy enables real‐time imaging and adaptive treatment but may introduce magnetic field effects that alter dose deposition. Accurate dose calculation in such settings requires detailed Monte Carlo (MC) modeling. Purpose To develop and validate a detailed MC model of the 0.5 T bi‐planar Linac‐MR with an integrated ...

Monte Carlo calculations of electrons impinging on a copper target: A comparison of EGSnrc, Geant4 and MCNP5

Applied Radiation and Isotopes, 2018
A simple geometry is used to compare several of the available Monte Carlo software codes for radiation transport. EGSnrc, Geant4 and MCNP5 are all used to calculate the photon fluence produced from electrons incident on a copper target. Four energies for the isotropic point source are chosen to simulate the average and maximum emission energies of 32P ...

A Monte Carlo approach to optimising a primary collimator design using EGSnrc

Physics Open
The primary collimator in a clinical linear accelerator (linac) plays a vital role in the radiation shielding of the machine. One objective of the collimation system is to reduce head leakage to less than 0.1 % relative to the dose on the central axis of
