The numerical model of thermal processes in domain of biological tissue subjected to an external heat source is discussed. The model presented is based on the second order dual–phase–lag equation (DPLE) in which the relaxation time and thermalization time thermalization time (τq and τT) are tak n into account. In this paper the homogeneous, cylindrical skin tissue domain is considered. The most important aim of the research is to compare the results obtained using the classical model (the first-orderDPLE) with the numerical solution resulting from the higher order form of this equation. At the stage of numerical computations the Finite Difference Method (FDM) is applied. In the final part of the paper the examples of computations are shown.

High Intensity Light

Because of its strong scattering effect in biological tissue, laser light (especially at near-infrared wavelength) can heat a comparatively large volume of tissue. This volume heating, coupled with other advantages (e.g. lasers can deliver high intensity light to small well-defined areas under precise control), makes the laser an excellent heat source. It can thus be used to achieve the thawing of frozen biological tissue. This may have great potentials in medicine (e.g. rewarming of cryopreserved biological tissue) and food industry.
