ULTRASOUND SYSTEMS AND METHODS FOR REAL-TIME NONINVASIVE SPATIAL TEMPERATURE ESTIMATION

摘要

Ultrasound systems and methods for real-time noninvasive spatial temperature estimation are disclosed herein. A method for noninvasive temperature estimation in accordance with an embodiment of the present technology can include, for example, propagating ultrasound waves into tissue and detecting echoes of the ultrasound waves. The ultrasound waves can become nonlinear as they propagate into the tissue. The method can further include monitoring changes in tissue temperature in real-time using a spectral-based temperature estimation approach, which correlates nonlinear acoustic effects with changes in tissue temperature.

1. A method of noninvasively treating tissue, the method comprising:
applying targeted energy to tissue at a treatment site; transmitting ultrasound waves that become nonlinear at a focal region in the tissue; detecting harmonics of the nonlinear ultrasound waves; and determining tissue temperature at the focal region in real-time using changes in the magnitudes of detected harmonics to estimate the tissue temperature, wherein greater attenuation of an individual harmonic correlates to an increase in the tissue temperature.
