      Abstract: During the past 35 years, the Implicit Monte Carlo (IMC) method proposed by Fleck and Cummings has been the standard Monte Carlo approach to solving the thermal radiative transfer (TRT) equations. However, the IMC equations are known to have accuracy limitations that can produce unphysical solutions. In this thesis, we explicitly provide the IMC equations with a Monte Carlo Cited by: IAEA Workshop on Monte Carlo Method in Medical Physics Attracts Participants from Around the World The ‘Gold Standard’ for Radiation Transport in Medicine On 17 – 28 October, medical physicists, scientists and engineers from around the world convened in Trieste Italy to participate in one of the largest IAEA workshops that’s ever been held.

This book is a guide to the use of Monte Carlo techniques in radiation transport. This topic is of great interest for medical physicists. Praised as a "gold standard" for accurate radiotherapy dose calculations, Monte Carlo has stimulated a high level of research activity that has produced thousands of papers within the past few years/5(2).

Modeling photon propagation with Monte Carlo methods is a flexible yet rigorous approach to simulate photon transport. In the method, local rules of photon transport are expressed as probability distributions which describe the step size of photon movement between sites of photon-tissue interaction and the angles of deflection in a photon's trajectory when a scattering event occurs.

MONTE CARLO IN RADIATION THERAPY. The Monte Carlo techniques have been used in various branches of radiation therapy,[8,9] from simulation of radiation therapy equipments and sources to dose calculation in various geometries.[10–18] For simulation of the photon and electron particles one has to apply the physics of transport for modeling, which requires the knowledge of interactions of the.

InHalton proposed using Monte Carlo algorithms to solve matrix problems by iteratively applying one of several variance reduction methods, including correlated sampling. More recently, Halton’s ideas were extended to the solution of continuous radiation transport problems by researchers at Los Alamos National Laboratory [ 14 ]–[ 17 Cited by: In what follows, the Monte-Carlo method applied to particle transport is detailed in terms of implementation in codes and features for radiation protection and dosimetric problems.
