A Feasibility Study for Microwave Breast Cancer Detection Using Contrast-Agent-Loaded Bacterial Microbots
Figure 3
(a) Illustration of the tumor sensing and diagnosis system using a configuration similar to [8, 11]. (b) Dielectric profile at for the coronal cross-section through the third antenna ring. We assume concentric magnetic field lines originating from a dc source via one of the antennas (marked with a “+”) during the propulsion-and-steering phase. All the eight antennas probe the breast sequentially with UWB pulses during the tracking phase after the MTB reach the targeted aggregation zones (marked with yellow circles). Two clumps of MTB are injected simultaneously into the breast. (c) Size estimation of the tumor by targeting it from different angles; the eight antennas are sequentially employed to carry a dc for generation of magnetic fields.
