Tests cases had been developed according to the Brazilian reality, having as reference the radiotherapy treatments carried out in the Instituto Nacional do Câncer. The system developed for checking the quality of treatment planning systems with electrons was efficient in evaluating the Eclipse planning system by identifying the failures of their algorithms, especially in planning the isodose. The verification system has been validated against the Monte Carlo method and the experimental data with an ionization chamber and showed the shortcomings of generalized pencil beam and eMC algorithms. The deviation of the results obtained with the Monte Carlo in relation to the eMC algorithm is higher than 3%, taking into account the statistical fluctuation inherent in the system in some case tests. 2019 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280831002 en 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.1 Vol.7 |
