ABSTRACT:
A noninvasive accurate method for measuring the temperature of tissue beneath the surface of a living body 11. Ultrasonic signals (14) are directed into beads 13 of a material that are inserted into the tissue with a syringe. The reflected signals (15) indicate the acoustic impedance or resonance frequency of the beads 13 which in turn indicates the temperature of the tissue. A range of temperatures around the melting temperature of the material can be measured by this method.
