We present our results regarding electromagnetic & thermal simulations as well as temperature measurement studies in anesthesized pigs. Pig models were generated by segmenting tissues from CT images. Fractionated dipole antennas were used to deliver RF energy in the pigs body. Power levels used for RF excitation were monitored. Temperature measurements were made using 4 fiber optic probes at locations which are visible in the digital pig model. Simulation and Experiment results were compared.
