چکیده

Breast cancer is a global health problem, needing cheep and effective alternative diagnosis methods in order to minimize the mortality. This experimental study is performed in the context of an ongoing collaborative project towards a future planar three-dimensional microwave breast mammography system. Herein the first quantitative image of an inhomogeneous breast tumor phantom, composed by different Triton X-100/water/salt mixtures, is obtained by using the existing planar 2.45 GHz microwave camera.

QUANTITATIVE IMAGING USING A 2.45 GHz PLANAR CAMERA

Microwave imaging is recognized as an efficient diagnostic modality for no 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 80’s, Supélec developed a 2.45 GHz planar microwa...

Experimental Assessment of Microwave Di- Agnostic Tool for Ultra-wideband Breast Cancer Detection

An ultra-wideband microwave imaging system that employs a heterogeneous breast phantom and covers the ultrawideband (UWB) frequency range (3.1 GHz to 10.6 GHz) is presented. The platform scanning system allows monostatic and bistatic mode of operation. In this work, developed heterogeneous phantoms are used to mimic the realistic breast tissues. A utilized tapered slot antenna array allows for ...
