Pereira Clarysson A. M. da Silva Biología PDD MCNP Radiotherapy In radiotherapy treatment planning, tools that improve the accuracy and quality of the radiation treatment for cancer are important for the decreased death of healthy tissue and the probability to produce cancer cells. This work aims to establish the simulation basis on MCNP code for reproducing the x-ray generation from the electron beam to the photon beam used on radiotherapy by the LINAC VARIAN 600 C/D. The main goal is to approximate the simulated x-ray spectrum, the profile dose and the relative dose to experimental ones. The analyzes show the difficulties to simulate a linear accelerator in relation to the relative percentage error between the simulation and experimental cases for the profile dose and the relative dose. These difficulties are due to the lack of information from the suppliers to the academic public in a matter of material composition, dimensions, and energies. Therefore, some parts of the model should be inferred, such as the electron beam source and its angle. The results show the data of the experimental measures compared to the Monte Carlo results, where the measurements of PDD are inside the margin of error for buildup region and the flat region for the beam profile dose according to reference criteria. The developed model would help to optimize the simulation of patient dosimetry in radiotherapy treatment planning. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280899008 es http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3 Vol.7 |
