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… (More)

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… (More)

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… (More)

Side-looking Intravascular Ultrasound Systems (IVUS) systems provide high resolution cross-sectional images of vascular structure. However, blood velocity estimation is hampered by the orthogonality… (More)

Previously, we presented a method of real-time arterial color flow imaging using an intravascular ultrasound (IVUS) imaging system, where real-time RF A-scans were processed with an FIR… (More)

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… (More)
