Dielectric characterization study of liquid-based materials for mimicking breast tissues

The possibility of mimicking different types of breast tissues to realize experimental phantoms has been investigated by measuring the complex permittivity of polyethylene glycol mono phenyl ether (Triton X‐100) and distilled water solutions. In this respect, broad band electromagnetic characterization of several mixtures, at different concentrations, has been carried out in the 0.5–12 GHz frequency range. The good fitting between the dielectric properties of mammary tissues and that of the proposed mixtures, and the stability against temperature in the range 18–30 °C, suggest the possibility of mimicking the dielectric characteristics of breast tissues using easily available and low cost materials. © 2011 Wiley Periodicals, Inc.
