We used Doppler Ultrasound and Phase Contrast MRI to
quantitatively characterize the frequency content of the
blood velocity waveform in different locations of the
body. The peripheral vessels had higher frequency
content with respect to the central vessels, and we
determined that a temporal resolution of 30 to 40 ms is
both necessary and sufficient to correctly characterize
the signal.
