Characterization of benign and malignant breast tissues using 2‐D microwave tomographic imaging

Dielectric permittivity studies and 2-D microwave tomographic imaging are performed on benign and malignant breast tissues to characterize these tumors at the ISM band. Significant difference in the permittivity values is obtained and a distinct characterization is done based on the nature of the permittivity profiles. Also, it is observed that benign tumors exhibit sharp images with well-defined borders, whereas malignant tumors show fuzzy and blurred boundaries. © 2007 Wiley Periodicals, Inc.
