• Generalized dual-phase lag equation is applied.
• 3D domain of biological tissue is under consideration.
• The diffusion approximation of light propagation in soft tissue is used in the paper.
• Tissue destruction according to the temperature impact is calculated.
In the paper a numerical analysis of thermal processes proceeding in a soft tissue subjected to a laser irradiation is presented. The transient bioheat transfer in the 3D domain considered is described by the generalized dual-phase lag equation. The internal heat source resulting from the laser irradiation based on the solution of the diffusion equation is taken into account. The process of the thermal destruction of the tissue is also analyzed. At the stage of numerical realization the explicit scheme of finite difference method is used. In the final part of the paper the results of computations for different variants of tissue porosity are shown.
