Abstract
A thermoacoustic imaging system and method for monitoring tissue temperature within a region of interest, which has an object of interest and a reference that are separated by at least one boundary. The system and method include a thermoacoustic imaging system with an adjustable radio frequency (RF) applicator configured to emit RF energy pulses into the tissue region of interest and heat tissue therein, 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 that process at least one received bipolar acoustic signal generated in the region of interest in response to the RF energy pulses to determine a peak-to-peak amplitude thereof and calculate a temperature at the at least one boundary using the peak-to-peak amplitude of the at least one bipolar acoustic signal.
