This investigation is focused on the effect of thermal-lag times associated with the thermal inertia and microstructural interaction as well as the impact of other thermo-physical parameters such as core body temperature and blood perfusion rate. A Backward Time, Cantered Space (BTCS) implicit scheme is employed for discretization through finite difference method (FDM). Finally, a comparison is proposed be-tween Penne's model, the Thermal wave model, and the DPL model to illustrate the effect of different relaxation times. Keyphrases: BTCS discretization scheme, Dual-Phase Lag model, Penne's bioheat model, Thermal Wave model, finite difference method
