Resumo: This work presents a methodology to perform simulations of cone beam tomography using the GATE code. Two computational models, ICRP110 and MASH3, were used for patient representation. For each model, 360 images were obtained representing the attenuation pattern of a 120kV photon beam when passing through the patient in a complete rotation. 3D CT images were reconstructed using a commercial program to evaluate the simulation approach, obtaining very satisfactory results. Moreover, our group found promising results using a reconstruction code under development. In addition, the deposited dose was obtained for each beam direction and the entire CT exam. The presented methodology can be used in further works to design and optimize new types of CT scanners.

Dois modelos antropomórficos computacionais, o ICRP110 e o MASH3, foram utilizados para representação dos pacientes. Para cada modelo foram obtidas 360 imagens representando o padrão de atenuação de um feixe de fótons de até 120kV ao passar pelo paciente numa rotação completa. Para avaliar a simulação, imagens de tomografia computadorizada 3D foram reconstruídas utilizando um programa comercial, obtendo-se resultados satisfatórios. Resultados promissores também foram obtidos utilizando um código de reconstrução em desenvolvimento pelo nosso grupo. Foram calculadas as doses depositadas para cada direção do feixe e para todo o exame tomográfico. A metodologia apresentada poderá ser utilizada em trabalhos futuros para o desenho e otimização de novos tipos de tomógrafos.Universidade Federal de Viçosa - UFV2024-01-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/jcec/article/view/1780310.18540/jcecvl10iss01pp17803The Journal of Engineering and Exact Sciences; Vol. 10 No. 1 (2024); 17803The Journal of Engineering and Exact Sciences; Vol. 10 Núm. 1 (2024); 17803The Journal of Engineering and Exact Sciences; v. 10 n. 1 (2024); 178032527-1075reponame:The Journal of Engineering and Exact Sciencesinstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/jcec/article/view/17803/9143Copyright (c) 2024 The Journal of Engineering and Exact Scienceshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMilian, Felix MasAmbrosio, Paulo EduardoIglesias, Susana MarreroHonda, Marcelo OssamuMartins, Allan MedeirosDominguez, Dany Sanchez2024-03-26T17:19:32Zoai:ojs.periodicos.ufv.br:article/17803Revistahttp://www.seer.ufv.br/seer/rbeq2/index.php/req2/oai2527-10752527-1075opendoar:2024-03-26T17:19:32The Journal of Engineering and Exact Sciences - Universidade Federal de Viçosa (UFV)false
