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. Here, a method is presented measuring relative blood speed using an FIR filter

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 mm diameter catheter appropriate for coronary artery appl

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 integrated angioplasty balloon and ultrasonic imaging probe. Becaus

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 with an intraluminal array imaging system appropriate fo

1997 IEEE Ultrasonics Symposium Proceedings. An International Symposium (Cat. No.97CH36118).
There are two primary reasons why intravascular ultrasound has not yet reached its potential for interventional cardiology. First, image quality has been poor given the possible operating frequencies and numerical apertures. And second, there is no a

Previous synthetic array methods for intraluminal imaging of coronary arteries have been greatly extended. First, a 64 element, high efficiency, ceramic piezoelectric, array transducer operating at 20 MHz has been constructed. The array is mounted on
