摘要： A method for determining an electromagnetic field spatial distribution of a radio frequency (RF) antenna which includes the steps of emitting with the RF antenna, a plurality of RF energy pulses into a homogeneous medium; performing a plurality of thermoacoustic signal measurements of the plurality of RF energy pulses, wherein each of the thermoacoustic signal measurements is performed in a similar manner; utilizing a variance in the plurality of thermoacoustic signal measurements to generate a reconstructed pressure distribution for a volume located within the homogeneous medium; and calculating the RF antenna electromagnetic field spatial distribution within the volume based upon the reconstructed pressure distribution for the volume located within the homogeneous medium.
