Abstract
An optical fiber temperature sensing probe for implantation into a human body or other object that is being heated either by ultrasonic radiation alone or by a combination of ultrasonic and electromagnetic (radio frequency or microwave) energy. Several embodiments are described of probes adapted to measure temperature in an ultrasound field without errors being introduced by direct absorption of ultrasonic energy or by viscous heating, even when plastic fiber is utilized.
