Analytical expressions for transient temperature distributions within a two-zone heating probe and the surrounding infinite, isotropic, homogeneous, perfused medium are obtained. The periphery of the probe simulates the stagnant blood layer which usually forms around a thermistor probe if it is inserted into the tissue. A procedure to estimate thermal properties of tissues in vivo using these results is also outlined.
