METHOD AND SYSTEM FOR ENHANCING RF ENERGY DELIVERY DURING THERMOACOUSTIC IMAGING

摘要

A method and system for enhancing radio frequency energy delivery to a tissue region of interest. The method and system direct with a radio frequency (RF) applicator, one or more RF energy pulses into the tissue region of interest, the tissue region of interest comprising an object of interest and at least one reference that are separated by at least one boundary; detect with an acoustic receiver, at least one bipolar acoustic signal generated in the tissue region of interest in response to the RF energy pulses and processing the at least one bipolar acoustic signal to determine a peak-to-peak amplitude thereof; adjust the RF applicator to maximize the peak-to-peak amplitude of bipolar acoustic signals generated in the tissue region of interest in response to RF energy pulses generated by the adjusted RF applicator; and direct with the adjusted RF applicator, one or more RF energy pulses into the region of interest.
