Abstract
A method for noninvasive in situ estimation of intensity in ultrasound hyperthermia is presented. The method employs the nonlinear theory of sound propagation in a focused ultrasound hyperthermia system in order to determine the focal field intensity, where the sound intensity levels are relatively high in the focal volume
