This paper concerns modification of the thermal tomography reconstruction algorithm to improve the speed of calculations for faster reconstruction of thermal and geometrical parameters inside a tested structure. We propose to solve the inverse problem in the two step procedure. First, initial rough reconstruction of a tested structure based on the one dimensional (1-D) thermal model. Second, execution of the full 3-D reconstruction procedure, with the first step result as the initial condition for further calculations. To verify value of the proposed method some simulation results of the phantom structure developed for testing the method as well as real reconstruction of this phantom are presented.

The aim of this paper is to discuss properties of the finite difference method in numerical simulations of heat transfer in skin. The analysis is done for the proposed model implemented in Borland C++ Builder, for static and transients conditions and external excitation. The results of simulation are compared to the simulation results in I-DEAS® Finite Element Modeling (FEM) and to thermograms recorded in animal experiments. Numerical model is implemented for one and three-dimensional heat transfer model.
