Transthoracic CUDA Feasibility in Human Volunteers

(Left) Conventional ultrasound image showing the region of interest selected for coronary ultrafast Doppler angiography (CUDA) processing. This real-time imaging mode of the ultrasound scanner was used for positioning (the scale bar is in centimeters). (Middle) Ultrafast B-mode images of the region of interest depicted in yellow. The resolution is lower, but the edges of the myocardial wall can be detected. Note that contrary to the open-chest experiments, parenchyma echogenicity is present above the myocardium, because it is a transthoracic measurement. (Right) CUDA images of coronary veins in systole and coronary arteries in diastole.
