Resumo: | Breast cancer is the type of cancer that affects more women worldwide. Its early detection is key to achieve its treatment and, consequently, reduce its mortality rate. Mammography is considered the most suitable technique for this detection, which is based on the visualization of small structures and patterns that may represent cancerous lesions. But for visualization of these structures, the quality control of mammographic images and the training of residents and radiologists is required. With this in mind, this study aimed the development and confection of three breast simulators (phantoms) that serve these purposes. The materials used in this construction were analyzed and their attenuation coefficients were compared to simulated breast tissues. The phantoms were prepared in polymethylmethacrylate molds and plates, known as acrylic, and the test structures used were microcalcifications, simulated by limestone, and fibers, simulated by nylon. The phantoms I-a and I-b are intended to perform quality control and has its test structures placed in a mixture of paraffin gel and acrylic powder and dental wax, respectively. The phantom II is intended to conduct the training of residents and radiologists and has its test structures placed in dental wax. The detectability of the test structures was variable with the thickness of phantoms. After analysis and comparison of results between the phantoms made and the marketable phantom recommended by the national standard, made phantoms were validated. |

Sua detecção precoce é fundamental para realização do seu tratamento e, consequentemente, a redução da sua taxa de mortalidade. A mamografia é considerada a técnica mais adequada para esta detecção, que se baseia na visualização de pequenas estruturas e padrões que podem representar lesões cancerígenas. Porém, para visualização destas estruturas, o controle da qualidade das imagens mamográficas e o treinamento de residentes e radiologistas é necessário. Tendo isto em vista, este trabalho teve como objetivo o desenvolvimento e a confecção de três simuladores de mama (phantoms) que servem a estes propósitos. Os materiais utilizados nesta construção foram analisados e seus coeficientes de atenuação foram comparados aos tecidos mamários que simulam. Os phantoms foram confeccionados em moldes e placas de polimetilmetacrilato, conhecido como acrílico, e as estruturas de teste utilizadas foram as microcalcificações, simuladas por calcário, e as fibras, simuladas por nylon. Os phantoms I-a e I-b têm o propósito de realizar o controle de qualidade e possuem suas estruturas de teste inseridas em uma mistura de parafina em gel e acrílico em pó e cera, respectivamente. O phantom II tem o propósito de realizar o treinamento de residentes e radiologistas e possui suas estruturas de teste inseridas em cera de uso odontológico. A detectabilidade das estruturas de teste se mostrou variável com as espessuras dos phantoms. Após análise e comparação dos resultados entre os phantoms confeccionados e o phantom comercial recomendado pela norma nacional, os phantoms confeccionados foram validados.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de SergipePós-Graduação em FísicaUFSBRFísicaFísica médicaSimulador de mama (phantom)MamografiaTreinamentoControle de qualidadeBreast Simulator (phantom)MammographyTrainingQuality controlCNPQ::CIENCIAS EXATAS E DA TERRA::FISICADesenvolvimento de simuladores de mama para controle de qualidade e treinamentoinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFSinstname:Universidade Federal de Sergipe (UFS)instacron:UFSORIGINALANDERSON_VINICIUS_SILVA_ALVES.pdfapplication/pdf3314970https://ri.ufs.br/jspui/bitstream/riufs/5296/1/ANDERSON_VINICIUS_SILVA_ALVES.pdf8f4ad7583dc527eda1788a73ed76cd56MD51TEXTANDERSON_VINICIUS_SILVA_ALVES.pdf.txtANDERSON_VINICIUS_SILVA_ALVES.pdf.txtExtracted texttext/plain114995https://ri.ufs.br/jspui/bitstream/riufs/5296/2/ANDERSON_VINICIUS_SILVA_ALVES.pdf.txte4a0044375e5a1fb2072dd490f06ab5eMD52THUMBNAILANDERSON_VINICIUS_SILVA_ALVES.pdf.jpgANDERSON_VINICIUS_SILVA_ALVES.pdf.jpgGenerated Thumbnailimage/jpeg1360https://ri.ufs.br/jspui/bitstream/riufs/5296/3/ANDERSON_VINICIUS_SILVA_ALVES.pdf.jpg6f30bef87217a6eaaefc73dd53670313MD53riufs/52962017-11-29 20:01:45.101oai:ufs.br:riufs/5296Repositório InstitucionalPUBhttps://ri.ufs.br/oai/requestrepositorio@academico.ufs.bropendoar:2017-11-29T23:01:45Repositório Institucional da UFS - Universidade Federal de Sergipe (UFS)false |
