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.
