Adaptive Spatiotemporal Filtering for Coronary Ultrafast Doppler Angiography
The heart's supply of oxygen and nutrients relies on the coronary vasculature, which branches from millimeter-sized arteries down to micrometer-sized capillaries. To date, imaging technologies can only detect large epicardial coronary vessels, whereas the intramural coronary vasculature remains...

| Résumé: | The heart's supply of oxygen and nutrients relies on the coronary vasculature, which branches from millimeter-sized arteries down to micrometer-sized capillaries. To date, imaging technologies can only detect large epicardial coronary vessels, whereas the intramural coronary vasculature remains invisible due to cardiac motion. We recently introduced coronary ultrafast Doppler angiography, a noninvasive vascular imaging technology based on ultrafast ultrasound that enables the visualization of epicardial and intramural coronary vasculature in humans. In this letter we describe, using an open-chest swine data set, the adaptive spatiotemporal filtering method that was developed for the detection of slow blood flows embedded in rapid myocardial motion |
