Resumo: In order to evaluate the isodose curves furnished by the manufacturer with "Eldorado 78" Telecobait unit, measurements of the percentage depth dose in the central ray and beam profile at 5cm depth were done. The experimental values of the percentage depth dose and from isodose curves furnished by the manufacturer were compared with those values published by British Journal of Radiology Suplement 11 and a desagreement was found in some cases. The experimental values beam profile were compared with those obtained from isodose curves furnished by the manufacturer. A table of percentage depth dose were made from the experimental values for clinical use.

Os dados relativos à porcentagem de dose profunda obtidos experimentalmente e através das curvas de isodose fornecidas pelo fabricante foram comparados com os dados do Suplemento n° 11 do British Journal of Radiology. A comparação mostra uma boa concordância entre os dois primeiros e um desvio de até 5mm, entre os pontos 50%, em relação aos valores publicados pelo B. J. R.. Entre os perfis de feixe experimentais e os obtidos através das curvas de isodose fornecidas pelo fabricante, também foi encontrado um desvio de até 2mm na região de dose de 50%. Uma tabela de porcentagem de dose profunda foi obtida a partir dos dados experimentais.INCA2023-08-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigos, Avaliado pelos paresapplication/pdfhttps://rbc.inca.gov.br/index.php/revista/article/view/360510.32635/2176-9745.RBC.1978v28n4.3605Revista Brasileira de Cancerologia; Vol. 28 No. 4 (1978): July/Aug.; 47-59Revista Brasileira de Cancerologia; Vol. 28 Núm. 4 (1978): jul./ago.; 47-59Revista Brasileira de Cancerologia; v. 28 n. 4 (1978): jul./ago.; 47-592176-9745reponame:Revista Brasileira de Cancerologia (Online)instname:Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA)instacron:INCAporhttps://rbc.inca.gov.br/index.php/revista/article/view/3605/2492https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAlexandre, Antonio CarlosSibata, Cláudio HissaoAlmeida, Carlos Eduardo de2023-08-11T16:07:20Zoai:rbc.inca.gov.br:article/3605Revistahttps://rbc.inca.gov.br/index.php/revistaPUBhttps://rbc.inca.gov.br/index.php/revista/oairbc@inca.gov.br0034-71162176-9745opendoar:2023-08-11T16:07:20Revista Brasileira de Cancerologia (Online) - Instituto Nacional de Câncer José Alencar Gomes da Silva (INCA)false
