Phased Arrays Pre-treatment Evaluation in Antitumoral Hyperthermia

There is general consensus that quality of hyperthermia treatment is a key factor for clinical effectiveness. The optimal treatment is defined by efficient tumor heating without patient discomfort by hot spots. Two optimization methods with the constraint on amplifier nominal power are presented. A voxel-based numerical analysis is performed for 8 dipoles on two rings, positioned around a head/neck volume within a distilled-water bolus. The optimization methods are compared on the basis of the maximal absolute power delivered to the target and other previously defined parameters
