On the efficient estimation of blood velocities
conference contribution
posted on 2009-12-08, 10:14 authored by Zhuo Zhang, Andreas Jakobsson, M.D. Macleod, Jonathon ChambersPulsed wave (PW) Doppler ultrasound systems are commonly
used to examine blood flow dynamics and the technique
plays a very important role in numerous diagnostic
applications. Commonly, narrow-band PW systems estimate
the blood velocity using an autocorrelation-based estimator.
Herein, we examine a recently proposed hybrid frequency
estimator, and via extensive numerical simulations
using simulated blood scatterers show the achievable performance
gain of this method as compared to the traditional
approach.
