SPECIFIC ABSORPTION RATE MEASUREMENT AND ENERGY DELIVERY DEVICE CHARACTERIZATION USING THERMAL PHANTOM AND IMAGE ANALYSIS Abstract s A method of predicting a radiation pattern emitted by an energy applicator includes the steps of providing thermal profile data for an energy applicator (2210), determining a specific absorption rate around the energy applicator as a function of the thermal profile data (2220), and generating a simulated radiation pattern for the energy applicator as a function of the determined specific absorption rate (2230). r221 0 PROVIDE THERMAL PROFILE DATA FOR AN ENERGY APPLICATOR I_ r.2220 DETERMINE A SPECIFIC ABSORPTION RATE AROUND THE ENERGY APPLICATOR AS A FUNCTION OF THE THERMAL PROFILE DATA I r-2230 GENERATE A SIMULATED RADIATION PATTERN FOR THE ENERGY APPLICATOR AS A FUNCTION OF THE SPECIFIC ABSORPTION RATE AROUND THE ENERGY APPLICATOR r2310 ACQUIRE TIME-SERIES IMAGE DATA ASSOCIATED WITH AN ENERGY 1
