Journal ArticleDOI
Comparison of carotid artery blood velocity measurements by vector and standard Doppler approaches.

TL;DR: The results of this study suggest that the introduction of vector Doppler methods in commercial machines may finally be considered mature and capable of overcoming the angle-dependent overestimation typical of the standard spectral Dopplers approach.
Journal ArticleDOI
Interaction between secondary velocities, flow pulsation and vessel morphology in the common carotid artery.
TL;DR: The analysis of several velocity profiles confirms that the velocity distribution is markedly asymmetrical, especially during the deceleration phase following the systolic peak, and a tentative explanation for such behavior is given by correlating it with the growth of secondary flows caused by the slight vessel curvature and viscous effects.
Journal ArticleDOI
Differences between internal jugular vein and vertebral vein flow examined in real time with the use of multigate ultrasound color Doppler.
TL;DR: The results support the view that other outflow pathways, like the vertebral plexus, play a major role in the normal physiology of brain circulation and must be assessed to obtain a complete picture of blood outflow.
Journal ArticleDOI
An FFT-based flow profiler for high-resolution in vivo investigations
TL;DR: The operation of a newly developed multigate instrument capable of performing, in real time, 64-point fast Fourier transforms of Doppler signals sampled from 64 different range cells is discussed.
Journal ArticleDOI
On the interaction between ultrasound and contrast agents during Doppler investigations.
TL;DR: An original model describing the bubble dynamics as the outcome of the balance between US radiation force and fluid drag force is validated for the case in which bubbles are suspended in blood and the high fluid viscosity is shown to prevent significant bubble deviations from the unperturbed fluid streamlines.
