摘 要：This research aims at designing a non-invasive, low-cost, and portable imaging device for cancer screening. Conceptualization, architectural and system-level design, and finally implementation of the system called TUSI, Time-Domain Ultra-Wideband Synthetic Imager, are addressed. Using an array of closely controlled radiating silicon chips, acting as transceivers in microwave /mm-wave frequencies, this device transmits short “beam-steered” pulses and picks up reflections from tissue abnormalities (e.g. cancerous tissue). By processing the data from multiple transceivers, a larger aperture is synthesized. In essence, this imager probes the “electrical” properties of the tissue.
