Compressive sampling reconstruction for local-only CT imaging
This technology reconstructs detailed CT images by scanning only a specific region of interest rather than the entire body, using mathematical techniques borrowed from compressed sensing to fill in what the truncated scan cannot directly measure. It exploits the fact that medical images tend to be sparse — meaning most areas are relatively uniform — to accurately recover a sharp local image from far less data than a full scan requires. A parallel version uses multiple X-ray sources simultaneously to capture the region faster, improving temporal resolution. The net result is clinically useful images of, say, a heart or tumor site with meaningfully lower radiation exposure than conventional whole-field CT.
What you could build
A software reconstruction module or embedded algorithm licensed to CT scanner manufacturers (Siemens Healthineers, GE HealthCare, Canon Medical) that enables true interior-only scanning modes, reducing dose in targeted applications such as cardiac CT, dental CBCT, and interventional radiology guidance.
Who in Virginia should care
Northern Virginia and Reston-area health IT and medical imaging software firms, plus defense and intelligence agencies in the region that use CT-based inspection for security screening or non-destructive evaluation.
Readiness: Lab validated
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
