A hyperthermia thermometry system using an ultrasound nonlinear effect caused by superposed pulses was developed. A feasibility study was made to obtain temperature mapping of tissue phantoms and of anesthetized pigs heated by an ultrasound applicator. The thermometry system consists of a mechanical sector scanner and a mainframe with a color monitor. The distribution of the temperature rise is calculated within one minute, and displayed on the monitor together with an ultrasound B-mode image. Experimental results show that a reasonable temperature rise mapping was obtained in both objects, agreeing to within 2°C with the data obtained by thermocouples located in the phantom
