introduction after the publication of task group number 43 dose calculation formalism by the american association of physicists in medicine (aapm), this method has been known as the most common dose calculation method in brachytherapy treatment planning. in this formalism, the water phantom is introduced as the reference dosimetry phantom, while the attenuation coefficient of the sources in the...

The Monte Carlo program WWGENPV, designed for computing distributions and generating events for the four-fermion process ee → WW → 4f , is described. It is based on the calculation of the exact tree-level matrix element of the four-fermion reaction and includes initial-state radiation in the leading-log approximation within the structure function approach. The program can be used in a two-fold ...

A Monte Carlo radiation transport simulation program, EGS Nova, and a Computer Aided Design software, BRL-CAD, have been coupled within the framework of Sindbad, a Nondestructive Evaluation (NDE) simulation system. In its current status, the program is very valuable in a NDE laboratory context, as it helps simulate the images due to the uncollided and scattered photon fluxes in a single NDE sof...

Monte Carlo ray tracing programs are now being used to solve many optical analysis problems in which the entire optomechanical system must be considered. In many analyses, it is desired to consider the effects of diffraction by mechanical edges. Smoothly melding the effects of diffraction, a wave phenomenon, into a ray-tracing program is a significant technical challenge. This paper discusses t...

A new release of the parametric detector Monte Carlo program SIMDET (version 4.01) is now available. We describe the principles of operation and the usage of this program to simulate the response of a detector for the TESLA linear collider. The detector components are implemented according to the TESLA Technical Design Report. All detector component responses are treated in a realistic way usin...

A Monte Carlo program is presented that computes all four fermion processes in e + e − annihilation. QED initial state corrections and QCD contributions are included. Fermions are taken to be massless, allowing a very fast evaluation of the matrix element. A systematic, modular and self-optimizing strategy has been adopted for the Monte Carlo integration, that serves also as an example for furt...

Introduction: Monte Carlo calculation method is considered to be the most accurate method for dose calculation in radiotherapy. The purpose of this research is comparison between 6 MV Primus LINAC simulation output with commissioning data using EGSnrc and build a Monte Carlo geometry of 6 MV Primus LINAC as realistically as possible. The BEAMnrc and DOSXYZnrc (EGSnrc package) M...

The game of the Amazons is a quite new game whose rules stand between the game of Go and Chess. Its main difficulty in terms of game programming is the huge branching factor. Monte-Carlo is a method used in game programming which allows us to overcome easily this problem. This paper presents how the Monte-Carlo method can be best adapted to Amazon programming to obtain a good level program, and...

The structure of the framework is presented schematically in Fig. 1. The main class FairRunManger handles the overall program flow and the communication between different modules, namely Geometry Interface, RunTime DataBase , Event Generators, IO Manager and the Virtual Monte Carlo. The latter is an interface to differents Monte Carlo engine (Geant3, Geant4 and Fluka) allowing the user to choos...

We have investigated the application of Monte Carlo significance tests to the verification of reference ranges in the context of the transfer of an established range from one laboratory to another. Here we present an introduction to the Monte Carlo technique, outline a procedure for performing these tests using a commercially available software program, and demonstrate some of the operating cha...
