The temperature profile in the depth of a biological tissue is reconstructed from multispectral microwave radiometric data using an optimisation strategy. Starting from a simplified model with an assumed temperature distribution, radiometric data for different frequencies (skin depths) are computed. After adding `measurement noise¿, this computer-simulated data set is then inverted by the pattern-search strategy to yield a reconstructed temperature profile.
