METHOD AND SYSTEM FOR ESTIMATING FRACTIONAL FAT CONTENT OF AN OBJECT OF INTEREST

Abstract:

A method and system for estimating fractional fat content of an object of interest. The method and system include a thermoacoustic imaging system comprising an adjustable radio frequency (RF) applicator configured to emit RF energy pulses into the region of interest and heat tissue therein and an acoustic receiver configured to receive bipolar acoustic signals generated in response to heating of tissue in the region of interest; and one or more processors. The one or more processors are able to process bipolar acoustic signals received by the acoustic receiver in response to RF energy pulses emitted into the region of interest using the RF applicator to determine a setting for the RF applicator that yields bipolar acoustic signals with at least one enhanced metric thereof, determine an impedance of the RF applicator used to yield acoustic bipolar signals with the enhanced at least one metric, and estimate fractional fat content of the object of interest using the determined impedance.
