title: Production and manipulation of elevated temperatures in pig abdomen with a three-electrode capacitive heating device.
abstract: The ability of a three-electrode capacitive heating device operating at 13.56 MHz to produce and effect spatial redistribution of hyperthermic temperatures is demonstrated through abdominal heating studies conducted with 80 kg female and 65 kg male pigs. Temperature-time profiles over the respective heating periods were obtained in anterior and posterior superficial tissue and in selected abdominal organs. At selected times during heating, spatial redistribution of elevated temperatures was effected through adjustment of power settings for one or more of the three electrodes, i.e. through manipulation of the specific absorption rate (SAR) in-vivo.
