CSnrc: correlated sampling Monte Carlo calculations using EGSnrc.

Medical physics, 2004
CSnrc, a new user-code for the EGSnrc Monte Carlo system is described. This user-code improves the efficiency when calculating ratios of doses from similar geometries. It uses a correlated sampling variance reduction technique. CSnrc is developed from an existing EGSnrc user-code CAVRZnrc and improves upon the correlated sampling algorithm used in an ...

Simulation of phoswich detectors using MCNPX and EGSNRC

Radiation Protection Dosimetry, 2010
The in vivo monitoring Lab at KIT uses two phoswich detectors for routine lung counting. A simplified model of one of them has been implemented in the two Monte Carlo codes EGSnrc and MCNPX. The active part of the detector consists of a crystal of NaI(Tl) and one of CsI(Tl): the energy deposited in both the crystals have been studied to consider the ...

Poster ‐ 18: New features in EGSnrc for photon cross sections

Medical Physics, 2016
Purpose:To implement two new features in the EGSnrc Monte Carlo system. The first is an option to account for photonuclear attenuation, which can contribute a few percent to the total cross section at the higher end of the energy range of interest to medical physics.

An EGSnrc Monte Carlo‐calculated database of TG‐43 parameters

Medical Physics, 2008
Monte Carlo methods are used to calculate a complete TG‐43 dosimetry parameter data set for 27 low‐energy photon emitting brachytherapy sources (18 and 9 ). All Monte Carlo calculations are performed using the EGSnrc user‐code BrachyDose. TG‐43 dosimetry parameters, including dose rate constants, radial dose functions (with functional fitting ...
