I used the technique that William so succinctly described to track
blood flow in the uterine artery from ultrasound data in a study
at the University of Colorado.  Since the reflection of ultrasound
from a moving target produces a doppler effect, the spectrum of
frequencies recorded from the reflection of an artery gives a good
idea of the differing velocities of blood flow in the artery.

Arterial constriction and dyastolic and systolic blood flow could be
quite easily seen in the resulting sonogram.  I released the code
to the public domain.  You can find it in the edsnd package for the
NeXT at princeton.edu and sonata.cc.purdue.edu.
