Blood speed imaging with an intraluminal array
TLDR
In applications in which Doppler processing is not possible, such as side-looking intravascular imaging systems, decorrelation methods can be used to estimate blood speed. Expand

Synthetic phased arrays for intraluminal imaging of coronary arteries
A 64-element, high efficiency, ceramic piezoelectric array transducer operating at 20 MHz has been constructed for ultrasonic intraluminal imaging. The array is mounted on the surface of a 1.2 mmExpand

Coronary artery flow imaging with an intraluminal array
The rate of blood speckle decorrelation for scatterers moving through the imaging plane of an intravascular system can be used to estimate flow velocity. The authors have tested this hypothesis withExpand
