Abstract:
A method and apparatus for automated detection of a general, non-sinusoidal type of periodicity in ultrasound Doppler signals from pulsatile blood flow is described. The method computes a measure of pulsatility from the power spectrum near the peaks of the fundamental and harmonic frequencies of the Doppler signal information.
