Abstract
An optical fiber temperature sensing probe is implanted 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. In order to measure temperature in an ultrasound field without the probe introducing errors, the probe is made to be substantially thermally non-conducting, made of materials that do not absorb compressional energy, and has a small diameter relative to the length of the ultrasonic heating waves.
