Monte Carlo radiation transport in external beam radiotherapy

The Use of Monte-carlo Codes for Treatment Planning in External- Beam Radiotherapy

Monte Carlo simulation of radiation transport is a very powerful technique. There are basically no exact analytical solutions to the Boltzmann Transport equation. Even the "straightforward" situation (in radiotherapy) of an electron beam depth-dose distribution in water proves to be too difficult for analytical methods without making gross approximations such as ignoring energy-loss straggling,...

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. ...

Dosimetry Studies of Different Radiotherapy Applications using Monte Carlo Radiation Transport Calculations

Čerenkov radiation emission and excited luminescence (CREL) sensitivity during external beam radiation therapy: Monte Carlo and tissue oxygenation phantom studies

Radiotherapy generates Čerenkov radiation emission in tissue, and spectral absorption features appearing in the emission spectrum can be used to quantify blood oxygen saturation (S(t)O(2)) from the known absorptions of hemoglobin. Additionally, the Čerenkov light can be used to excite oxygen-sensitive phosphorescence of probe PtG4, whose emission lifetime directly reports on tissue oxygen parti...

Comparison of Monte Carlo Methods for Nonlinear Radiation Transport

Five Monte Carlo methods for solving the nonlinear thermal radiation transport equations are compared. The methods include the well-known Implicit Monte Carlo method (IMC) developed by Fleck and Cummings, an alternative to IMC developed by Carter and Forest, an “exact” method recently developed by Ahrens and Larsen, and two methods recently proposed by Martin and Brown. The five Monte Carlo met...
