Acesso em:.https://repositorio.ufpa.br/handle/2011/8878The inverse problem of parameter estimation for the bioheat transfer problem in sintetic tissue was analyzed. Initially an experimental analysis was developed by heating a synthetic tissue using a ultrasound transducer. Different temperature profiles were obtained for 3 cases involving intensity variations: 1W/cm2, 1.5W/cm2 and 2W/cm2 for 3 thermocouples positioned along the sintetic tissue. A mathematical model was develeped to represent the experimental problem. The solution of this model was obtained using the Classical Integral Transform Technique (CITT). The Levenberg-Marquardt Method was used to solve the parameter estimation for the attenuation of sintetic tissue. A comparison between experimental solution and the mathematical model was performed.Acesso AbertoCalor - TransmissãoTransformadas integraisUltrassomBiotransferência de calorHeat - TransmissionIntegral transformsUltrasoundHeat biotransferTeseCNPQ::ENGENHARIAS::ENGENHARIA QUIMICACNPQ::ENGENHARIAS::ENGENHARIA BIOMEDICA::BIOENGENHARIA
