Resumo: | Thermographic breast exams are physiological exams that capture the body temperature by infrared rays. They have the characteristic of detecting abnormalities in the temperature distribution over the body surface, indicating the presence of lumps before they even begin to be palpable. In addition, other advantages associated with this exam are: non- invasiveness; possibility of performing preventive exams in young women; low cost. This work aims to develop a tool for the automatic construction of three-dimensional bresat models using thermographic examinations of the breasts that have five images at different angles obtained from the Visual Lab DMR’s database: frontal view, oblique on the right lateral view, oblique on the left lateral view, right lateral view and left lateral view. The work has two key points: segmentation and geometric transformation. In segmentation, u-net, that is a variant of convolutional neural networks, is used. Five networks are created, each of them is responsible for segmenting one of the five exam images. The geometric transformation, on the other hand, transforms the dimensionality of the points of the curves of the breasts from the two-dimensional to the three-dimensional plane. These new 3D plane curves are used to build the model’s surface using Rational Non-uniform B-splines Surface (NURBS). Finally, texture mapping is performed to design the frontal thermographic examination on the model. In order to evaluate the three-dimensional models constructed and to evaluate the comparison between the proposed methodology and the literature, a research based on the Likert scale was carried out, with five points, for 15 people, among them: health specialists, 3D modelers and experienced academics to the theme. The result was evaluated as satisfactory, as there was a high approval rate for the models agreeing with the statements made. However, there are still many opportunities for improvement, evidenced during development and also pointed out during the survey. |

Possuem a característica de detectar as distribuições anormais de temperaturas na superfície do corpo, indicando a presença de nódulos antes mesmo deles começarem a ser palpáveis. Além disso, outras vantagens associadas a este exame são: não ser invasivo; possibilidade de realização de exames preventivos em mulheres jovens; e também possui baixo custo. Este trabalho tem como objetivo desenvolver uma ferramenta para a construção automática de modelos tridimensionais das mamas utilizando exames termográficos das mamas que possuem cinco imagens em ângulos diferentes obtidos da base de dados da Visual Lab DMR: frontal, lateral direita oblíqua, lateral esquerda oblíqua, lateral direita total e lateral esquerda total. O trabalho possui dois pontos-chave: segmentação e transformação geométrica. Na segmentação, é utilizada uma variante das redes neurais convolucionais, a u-net. Cinco redes são criadas, cada uma é responsável por segmentar uma das cinco imagens do exame. Já a transformação geométrica, realiza a transformação de dimensionalidade dos pontos das curvas das mamas do plano bidimensional para o tridimensional. Estas novas curvas no plano 3D são utilizadas para construção da superfície do modelo utilizando Non-Uniform Rational B-splines Surface (NURBS). Por fim, é realizado o mapeamento de textura para projetar o exame termográfico frontal no modelo. Com o propósito de avaliar os modelos tridimensionais construídos e avaliar a comparação entre a metodologia proposta e a metodologia da literatura, uma pesquisa baseada na escala Likert, de cinco pontos, foi conduzida para 15 pessoas, entre elas: especialistas da área da saúde, modeladores tridimensionais e acadêmicos afins ao tema. O resultado foi avaliado como satisfatório, uma vez que houve uma alta taxa de aprovação dos modelos ao se concordar com as afirmações realizadas. Entretanto, ainda há muitas oportunidades de melhoria, evidenciadas durante o desenvolvimento e apontadas, também, durante o questionário.Submitted by Jonathan Sousa de Almeida (jonathan.sousa@ufma.br) on 2022-06-20T18:34:44Z No. of bitstreams: 1 GLEIDSONMENDESCOSTA.pdf: 8319599 bytes, checksum: 0a4d9fdc12ae0a8522f47fd2499559f3 (MD5)Made available in DSpace on 2022-06-20T18:34:44Z (GMT).
