METHOD AND SYSTEM FOR ENHANCING RF ENERGY DELIVERY DURING THERMOACOUSTIC IMAGING

Abstract: a method and system for enhancing radio frequency energy delivery to a region of interest is disclosed. the method includes emitting with a radio frequency (rf) applicator comprising a waveguide and a feed probe, one or more rf energy pulses into the region of interest, detecting with an acoustic receiver, at least one multipolar acoustic pressure wave generated in the region of interest in response to the emitted one or more rf energy pulses and processing data of the at least one multipolar acoustic pressure wave to determine a peak-to-peak amplitude thereof, adjusting a direct-current between the waveguide and the feed probe to tune the rf applicator based on the determined peak-to-peak amplitude, and emitting with the tuned rf applicator, one or more rf energy pulses into the region of interest.
