Ultrafast Doppler has been accepted as a novel modality for small vasculature imaging with
high sensitivity, high spatiotemporal resolution, and high penetration. However, the …

Vulnerable plaques associated with softer components may rupture, releasing thrombotic
emboli to smaller vessels in the brain, thus causing an ischemic stroke. Pulse Wave Imaging …

Although color flow imaging is one of the representative applications of the Doppler method,
it can estimate only the velocity component in the direction of ultrasonic propagation, that is …

WSS measurement is challenging since it requires sensitive flow measurements at a
distance close to the wall. The aim of this study is to develop an ultrasound imaging …

A blood mimicking fluid (BMF) is imperative for the evaluation of Doppler ultrasound.
Doppler ultrasound still causes errors due to some artifacts such as aliasing and presence of …

Non-invasive monitoring of atherosclerosis remains challenging. Pulse Wave Imaging (PWI)
is a non-invasive technique to measure the local stiffness at diastolic and end-systolic …

Wall shear stress (WSS) plays an important role in the formation, growth, and rupture of
atherosclerotic plaques in arteries. This study measured WSS in diseased carotid artery …

Plane wave compounding (PWC) is widely used to measure the propagation of shear
waves. Implementing PWC on most commercial ultrasound scanners is challenging …

The multi-angle Doppler method was introduced for the estimation of velocity vectors by
measuring axial velocities from multiple directions. We have recently reported that the …

We present a technique called photoacoustic vector-flow (PAVF) to quantify the speed and
direction of flowing optical absorbers at each pixel from acoustic-resolution PA images. By …
