Abstract
It has been observed that attenuation of a transmitted or reflected beam of ultrasound in tissue irradiated with such a beam having a power intensity in the tissue in the non-linear range will change measurably as the tissue temperature changes. Based upon this observation, a method and apparatus for non-invasive thermometry include periodically interrogating the tissue with an ultrasonic beam having a power intensity sufficient such that the power intensity of the beam in the tissue is in the non-linear range. Attenuation coefficients based upon the attenuation of the power intensity of the ultrasonic beam due to the tissue are then periodically determined. Temperature changes in the tissue are determined based upon differences between the determined attenuation coefficients.
