Wearable Sensor for High Accuracy Tissue Imaging using Reciprocity

Microwave imaging (MWI) is a desirable alternative for identifying anomalies (tumors) within the human body. Previous microwave imaging techniques have complex designs and large computational time for image reconstruction. In this paper, we present a simple and real-time imaging technique using inverse scattering. The proposed technique is demonstrated to detect anomalies using 4 different scenarios: a) separation between anomalies, b) anomalies sizes, c) permittivities of the anomalies, and d) frequency of the illuminated signal.
