In this study, the MAGIC- f polymer gel was used to determine the absorbed dose by external radiation therapy. The MAGIC- f gel was made under normal pressure and temperature conditions and irradiated with a Siemens 6MV linear accelerator at 10 × 10 cm2 and at a depth of 10 cm. While simulating the head of the accelerator unit by the Monte Carlo method with BEAMnrc code, the percentage depth do...
A new fusion–evaporation model LisFus for fast calculation of fusion residue cross-sections has been developed in the framework of the code LISE. This model can calculate very small cross-sections quickly due to its compared to programs using the Monte-Carlo method. Such type of fast calculations is necessary to estimate fusion residue yields. Using this model the program LISE has now the possi...
An algorithm of Monte Carlo code for the production of fast hadron leader in the proton-(anti)proton interaction by QCD process is discussed.
The C source code associated with the Simulation 101 preconference workshop (offered at the 2006 and 2007 Winter Simulation Conferences) is presented here. This paper begins with general instructions for downloading, compiling, and executing the software. This is followed by sections on four groups of the software, categorized by functionality: libraries, Monte Carlo simulations, discrete-event...
The RAVEN code has been under development at the Idaho National Laboratory since 2012. Its main goal is to create a multi-purpose platform for the deploying of all the capabilities needed for Probabilistic Risk Assessment, uncertainty quantification and data mining analysis. RAVEN is currently equipped with three different sampling strategies: Once-through samplers (Monte Carlo, Latin Hyper Cub...
background: the monte carlo method is the most accurate method for simulation of radiation therapy equipment. the linear accelerators are currently the most widely used machines in radiation therapy centers. methods: in this work, a monte carlo modelling of the siemens oncor linear accelerator in 6 mv and 18 mv beams was performed. the results of simulation were validated by measurements in wat...
An epithermal neutron beam has been designed for Boron neutron Capture Therapy (BNCT) at the thermal column of Tehran Research Reactor (TRR) recently. In this paper the whole body effective dose, as well as the equivalent doses of several organs have been calculated in this facility using MCNPX Monte Carlo code. The effective dose has been calculated by using the absorbed doses determined for e...
Introduction: The purpose of this study is to build homogeneous equivalent phantom chest in order to provide the necessary ability for checking the image quality in radiographic tests in four age groups of children in terms of the most recent age group categorization ICRP103. This phantom provides the features of weakness and discrepancies similar to body and can be consi...
The aim of this study was to estimate the delivered doses to tissues and organs around the liver tumor during radiotherapy and to determine organs with a high probability of secondary induction cancers. This study was carried out using Monte Carlo method. The used Phantom, the ORNL phantom is for an adult female. The volume of the tumor is as much as 30% of the liver tissue.In the initial step...
background: hdr brachytherapy is one of the commonest methods of nasopharyngeal cancer treatment. in this method, depending on how advanced one tumor is, 2 to 6 gy dose as intracavitary brachytherapy is prescribed. due to high dose rate and tumor location, accuracy evaluation of treatment planning system (tps) is particularly important. common methods used in tps dosimetry are based on computat...
