A Simple and Conservative Method to Include Variation of Core Blood Temperature with Pennes Bioheat Equation

Giuseppe Carluccio¹, Christopher Michael Collins¹

Pennes bioheat equation is one of most used models to predict temperature increase in body tissues. We present a simple and conservative method to include the variation of blood temperature increase in the Pennes bioheat equation due to the whole-body SAR absorption. Plots are provided showing the core blood temperature over time, and the spatial temperature increase distribution for a cross-section of the body obtained with both the Pennes bioheat equation having constant value of blood temperature, and the method with the time dependent blood temperature here presented.
