  Introduction: The use of Monte Carlo simulation methods is assumed to be one of the most accurate methods for calculation of dose distribution in a patient's body. Two pieces of software in MCNP code, which are applied for body simulation, are Scan2MCNP and CT2MCNP that operate based on the intensity of DICOM colour images and CT numbers respectively. Therefore, dose distribution obtained by these two methods is predicted to be different. The aim of this study is to evaluate dosage differences calculated by Scan2MCNP and CT2MCNP to simulate of low energy radioactive sources for brachytherapy of brain tumours. Material and methods: In this study, 125I (Model IR-Seed2) source manufactured by Iran was simulated by MCNPX code and then the accuracy of simulation was evaluated. Simulation of 125I implantation in brain was performed using Scan2MCNP and CT2MCNP programs. Comparison of the.. Read More»
