METHOD AND SYSTEM FOR DETERMINING A MATERIAL TYPE OF AN OBJECT OF INTEREST

Abstract:

A method for determining a material type of an object of interest comprises: directing, using a radio frequency (RF) source, RF energy into a region of interest, the region of interest comprising the object of interest, a known reference and a boundary between the object of interest and the known reference; detecting, using an acoustic receiver, at least one thermoacoustic multi-polar signal generated in response to the RF energy; correlating, by one or more processors, the at least one thermoacoustic multi-polar signal to a transmitted power correction factor to generate a corrected thermoacoustic multi-polar signal; and determining, by the one or more processors, the material type of the object of interest as a function of the corrected thermoacoustic multi-polar signal and a transmitted power of the RF energy.
