Discussion: Calculation of Electromagnetic Power Deposition

Abstract

C Durney began the discussion with introductory remarks. He stated that J Strohbehn and he had set the stage for this discussion with their talks given previously that day and would, therefore, not make further presentations. He then introduced C K Chou, who described his calculations for power absorption in a fat-muscle-bone cylinder irradiated by four applicators with E parallel to the axis of the cylinder. Measurements were made for the corresponding situation, with the applicators located far enough from the cylinder that their fields approximated plane waves. The calculations allowed them to adjust relative phases to optimize the SAR distribution. Close agreement between calculated and measured values was obtained.
