Displacement and strain imaging of coronary arteries with intraluminal ultrasound
Tissue elasticity can be estimated from displacement and strain images acquired under controlled deformation. We extend this approach for coronary arteries, deformed and imaged by an integratedExpand

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

Catheter arrays: can intravascular ultrasound make a difference in managing coronary artery disease
TLDR
A real-time, synthetic phased array system using a 64 element, high efficiency, ceramic piezoelectric transducer operating at 20 MHz. Expand

TLDR
We present a model of the slow-time spectrum for a constant z-direction speed and a method using it to make quantitative estimates of scatterer speed. Expand

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

Modified Weighting Method for Forward-Looking Ring-Annular Arrays
TLDR
A synthetic phased, ring-annular array is presented that achieves a transmit-receive aperture and on-axis performance comparable to a full aperture disk array. Expand

Ultrasonic displacement and strain imaging of coronary arteries with a catheter array
Tissue elasticity can be estimated from displacement and strain images acquired under controlled deformation. We extend this approach for coronary arteries, deformed and imaged by an integratedExpand
