Abstract :
A thermal response model of a simulated cranial structure (multilayered sphere) exposed to radiofrequency radiation (RFR) has been developed and experimentally verified for the no blood flow case. The thermal response model considers the RFR energy absorption distribution as predicted through use of the Mie theory, the thermal properties of the many layers, the blood flow to the central core area, and surface cooling through the application of a nonhomogeneous Newton cooling law. The model was preliminarily verified using homogeneous muscle equivalent spheres and a Vitek, Inc., model 101, electrothermia monitor.
