Abstract

Thermoacoustic contrast under RF illumination is a function of electrical conductivity and applied electric field, as well as mechanical and thermal properties. An array of phantom objects complement our RF testbed which illuminates with a controlled E field. All rely on electrical conductivity to generate TCT contrast. Inexpensive and easily fabricated resolution phantoms are highly conductive small inclusions with similar acoustic and thermal properties as background water bath. Tissue mimicking phantoms developed for microwave imaging have acoustic and dielectric properties similar to fat and muscle. Thermal properties are measured to completely quantify expected TCT contrast for experimental corroboration.
