Abstract
A non-invasive method of determining a temperature distribution in a targeted tissue volume treated with thermal therapy involves determining a baseline perfusion characteristic of the targeted tissue volume. A temperature distribution is calculated in the targeted tissue volume based on the baseline perfusion characteristic of the tissue, a microwave power input and a coolant temperature input. A perfusion characteristic of the targeted tissue volume is iteratively adjusted based on the calculated temperature distribution, and the temperature distribution is iteratively recalculated based on the adjusted perfusion characteristic, the microwave power input and the coolant temperature input throughout the thermal therapy.
