Termografia em engenharia biomédica ensaios exploratórios

Abstract

Este trabalho teve como principal objetivo a realização de ensaios exploratórios usando a Termogra a no âmbito da Medicina. Foram feitos ensaios de termografi a em duas regiões do corpo humano: face e membros inferiores. O trabalho focou-se principalmente sobre os membros inferiores, onde se estudou e acompanhou cirurgias de varizes. Os ensaios foram executados em dois locais: o primeiro (articulação temporomandibular), foi feito na Universidad de Valladolid, Espanha, e o segundo (membros inferiores) no Instituto Politécnico de Bragança e na Unidade Local de Saúde de Bragança. Em cada um dos locais usaram-se câmaras distintas: InfraTec modelo ImageIR®3300 e FLIR® modelo T365. Antecedem aos estudos clínicos a determinação dos métodos mais adequados para medir com esta tecnologia, onde se obtiveram tempos mínimos - 10 minutos - de aclimatação dos indivíduos estudados. As imagens obtidas através da câmara termográfi ca dos casos clínicos de varizes foram avaliadas em equipa pluridisciplinar (engenheiros e médicos) para uma melhor análise e interpretação dos resultados. Para cada caso clínico comparou-se ambos os membros inferiores, tendo-se veri- cado que em 75% dos casos houve um agravamento da perna saudável, e num dos casos houve o aparecimento de veias residuais. Concluíu-se que os exames termográ- ficos regulares no pós-operatório permitem acompanhar a recuperação do membro operado, bem como a evolução do membro não operado. A Termografi a mostrou-se fiável no diagnóstico desta patologia. Este trabalho levou à publicação de um artigo - Diagnostic evaluation of chronic venous insu ciency cases using thermal imaging - no VII EAT Congress on Thermology. The aim of this project is the exploratory use of thermography within Medicine. Thermography tests were made in two regions of the human body: face and inferior limbs. This project focused mainly on the inferior limbs, where varicose veins cases recommended for surgery were followed. The analyses were executed in two places: the first (temporomandibular joint), at Valladolid University, Spain; and the second (inferior limbs) at Polytechnic Institute of Bragança and at the Regional Hospital of Bragança. On each places di erent cameras were used : InfraTec ImageIR®3300 model and FLIR® T365 model. The most adequate steps to measure with this technology were determined prior to the clinical studies, where a minimum time of 10 minutes was obtained for the individuals to reach thermal equilibrium. A team of engineers and medical doctors, for a better analysis and interpretation of the results, evaluated the thermographic images. For every clinical case both inferior limbs were compared, and it was found that in 75% of the cases there was an aggravation of the healthy leg. In one of the cases residual veins appear. It was concluded that regular thermographic exams on post-operatory allow to accompany the recovery of the operated limb, as well as the evolution of the non-operated limb. Thermography has shown to be reliable on the diagnosis of this pathology. This project led to the publication of an article - Diagnostic evaluation of chronic venous insu fficiency cases using thermal imaging - in VII EAT Congress on Thermology.
