Abstract
The objective of this work was to estimate the parameters of the mathematical model used to represent the heating of a biological tissue. A sample of bovine muscle was used for the experiments. The tissue was heated with an electrical radiator, while its surface temperature was measured with an infrared camera. The imposed heat flux was estimated with a sample of Plexiglas, with known thermophysical properties. The Markov Chain Monte Carlo method and an Approximate Bayesian Computation algorithm were used for the solutions of the inverse problems examined in this work. The agreement of measured and estimated temperatures was excellent, thus demonstrating that the model and the estimated parameters appropriately represent the physics of the experiment.
