Investigation of Electron Beam Depth-dose Curve Using EGSnrc

Highlights in Science, Engineering and Technology
As a matter of fact, electron beam therapy is fundamental in cancer treatment, with advantage of precise dose deposition and shallow penetration, making it ideal for targeting superficial tumors in recent years. Accurate modelling of electron beam characteristics is important for safe and effective radiation therapy.

An embarassingly parallel framework for running EGSnrc/BEAMnrc/DOSXYZnrc,

, 2008
We present a computing framework for Monte Carlo simulation of radiation transport. In conformity with our belief that Monte Carlo studies should be anchored to physics but not to any particular code, we have enabled different Monte Carlo codes in this ...
