A Doppler System for Dynamic Vector Velocity Maps
Ultrasound in Medicine and Biology, 2002The aim of the vector Doppler technique is the quantitative reconstruction of a velocity field independently of the ultrasonic probe axis to flow angle. In particular, vector Doppler is interesting for studying vascular pathologies related to complex blood flows.

Introduction to vector velocity imaging
, 2010 Current ultrasound scanners can only estimate the velocity along the ultrasound beam and this gives rise to the cos() factor on all velocity estimates. This is a major limitation as most vessels are close to perpendicular to the beam. Also the angle varies as a function of space and time making it virtually impossible to compensate for the factor and ...

A new method for estimation of velocity vectors
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1998The paper describes a new method for determining the velocity vector of a remotely sensed object using either sound or electromagnetic radiation. The movement of the object is determined from a field with spatial oscillations in both the axial direction of the transducer and in one or two directions transverse to the axial direction.

Pulse centroid velocity of the Poynting vector
Journal of the Optical Society of America A, 2004The evolution of the pulse centroid velocity of the Poynting vector for both ultrawideband rectangular and ultrashort Gaussian envelope pulses is presented as a function of the propagation distance in a dispersive, absorptive dielectric material. The index of refraction of the material is described by the Lorentz-Lorenz formula in which a single ...
