ABSTRACT-
The Tissue Convective Energy Balance Equation is a newly developed thermal model for living tissues that was derived using a minumum of assumptions to evaluate the effects of blood flow. That derivation also provides a derivation for Pennes BHTE. This work will comparativley evaluate the accuracy of the predicitons of those two approaches and the scalar effective thermal conductivity method for a set of physiologically comparable hyperthermia situations, a comparison not previously done. In addition, an expanded version of the TCEBE's derivation will be presented that further quantifies the role of thermal entry lengths in evaluating the effects of blood flow on tissue temperatures during hyperthermia.
