We developed a method to drastically reduce computation time for solving the Pennes Bioheat equation, the most common equation used to estimate temperature in tissues due to SAR absorption. Given the geometry of the body and the SAR spatial distribution, the algorithm sequentially applies a digital filter to the solution of the Bioheat equation with the thermal conductivity neglected. The role of the filter is to estimate the effect of thermal conduction. Compared to temperature calculation methods based on FDTD methods, the algorithm can provide reasonably accurate results in a time about 60 times shorter.
