Internal displacement and strain imaging using ultrasonic speckle tracking
Previous ultrasound speckle tracking methods have been extended, permitting measurement of internal displacement and strain fields over a wide dynamic range of tissue motion. The markedly increasedExpand

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

Ultrasound elasticity imaging using Fourier based speckle tracking algorithm
Quantitative strain images of tissue equivalent phantoms have been obtained for a number of conditions using Fourier-based speckle tracking methods. Experimental results demonstrate that aExpand

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

Measurement of arterial wall motion using Fourier based speckle tracking algorithms
High resolution images are used to track the motion of small arteries under application of a static radial pressure. A Fourier-based method for tracking both radial and azimuthal motion over a wideExpand

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
