Motion-corrected cardiac CT reconstruction engine
This technology improves how CT scanners reconstruct images of the heart by using a triple-source helical cone-beam setup combined with a faster, mathematically precise image reconstruction algorithm. Traditional cardiac CT struggles with motion blur because the heart is constantly moving, requiring very fast data capture and processing. By using three X-ray sources simultaneously and a more efficient filtered backprojection algorithm, the system produces sharper, more temporally accurate images without the heavy computational cost of iterative methods. The result is higher-quality cardiac images that can be produced more quickly, which matters in clinical settings where scan throughput and diagnostic accuracy both affect patient outcomes.
What you could build
A hardware-software cardiac CT system or an OEM reconstruction software module licensed to CT scanner manufacturers (Siemens Healthineers, GE HealthCare, Canon Medical) that enables faster, higher-fidelity cardiac imaging with reduced radiation dose requirements; the primary buyers would be CT scanner OEMs or radiology software platform vendors.
Who in Virginia should care
Northern Virginia and Richmond-area hospital systems and radiology practices, as well as defense-adjacent medical imaging contractors supporting military health programs at facilities like Walter Reed National Military Medical Center nearby.
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.
