ABSTRACT

Microwave imaging is recognized as an efficient diagnostic modality for non-invasively visualizing dielectric contrasts in non-metallic bodies. The usefulness of this modality results from the existing correlation between dielectric properties and quantities of practical relevance for industrial or biomedical applications. At the beginning of the 80s, Supélec developed a 2.45 GHz planar microwave camera and in the 90s, the group developed algorithms for quantitative microwave imaging. The purpose of this study is to investigate the capability of these existing materials, or an extended version of it, in terms of quantitative imaging of high contrast inhomogeneous object for application of breast cancer detection.
