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

Ultrasound blood peak velocity estimates are routinely used for diagnostics, such as the
grading of a stenosis. The peak velocity is typically assessed from the Doppler spectrum by …

Two-dimensional angle-independent blood velocity estimates typically combine the Doppler
frequencies independently measured by two ultrasound beams with known interbeam …

Ultrasound vector Doppler techniques for three-dimensional (3-D) blood velocity
measurements are currently limited by low temporal resolution and high computational cost …

Several ultrasound (US) methods have been recently proposed to produce 2-D velocity
vector fields with high temporal and spatial resolution. However, the real-time …

Measurement of the maximum blood flow velocity is the primary means for determining the
degree of carotid stenosis using ultrasound. The current standard for estimating the …

Conventional ultrasound methods for acquiring color images of blood velocity are limited by
a relatively low frame-rate and are restricted to give velocity estimates along the ultrasound …

Current clinical ultrasound (US) systems are limited to show blood flow movement in either 1-
D or 2-D. In this paper, a method for estimating 3-D vector velocities in a plane using the …

Conventional ultrasound Doppler techniques estimate the blood velocity exclusively in the
axial direction to produce the sonograms and color flow maps needed for diagnosis of …

We describe a new method, called ensemble tracking, for estimating two-dimensional
velocities with ultrasound. Compared to previous speckle tracking techniques, ensemble …
