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

چکیده
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 a high resolution hemispherical scan, achieved by rotating the imaged object on a turntable. Full design details of the scanning system and the utilized post-processing algorithm are explained. To validate the reliability of the presented system, the results of several imaging cases, including the challenging low dielectric contrast case, are presented.
