Peripheral tissue freezing in cryosurgery.
The recently formulated bioheat equation of Weinbaum and Jiji which accounts for the vascular ultrastructure and blood perfusion was applied to the freezing of peripheral tissue. Using quasi-steady approximation the temperature distribution in the two-phase tissue and the motion of the frozen front were determined. Results are in good agreement with Pennes' bioheat equation.
