Vector flow techniques in the field of ultrasound encompass different pulse emission and
estimation strategies. Numerous techniques have been introduced over the years, and …

High frame rate (HFR) imaging methods based on the transmission of defocused or plane
waves rather than focused beams are increasingly popular. However, the production of HFR …

Quantitative blood velocity measurements, as currently implemented in commercial
ultrasound scanners, are based on pulsed-wave (PW) spectral Doppler and are limited to …

Several techniques can estimate the 2-D velocity vector in ultrasound. Directional
beamforming (DB) estimates blood flow velocities with a higher precision and accuracy than …

Ultrasound (US) examination of the common carotid artery was compared with a through-
plane magnetic resonance imaging (MRI) sequence to validate a recently proposed …

A method for estimating vector velocities using transverse oscillation (TO) combined with
directional beamforming is presented. In directional TO (DTO), a normal focused field is …

Blood velocity measurements are important in physiological science and clinical diagnosis.
Doppler ultrasound is the most commonly used method but can only measure one velocity …

This paper presents a vector flow imaging method for the integration of quantitative blood
flow imaging in portable ultrasound systems. The method combines directional transverse …

In this paper a global estimation method based on transverse oscillation to simultaneously
extract wall and flow velocities at high-framerate is presented. Several carotid phantoms with …

Volumetric flow rate estimation is an important ultrasound medical imaging modality that is
used for diagnosing cardiovascular diseases. Flow rates are obtained by integrating velocity …
