ABSTRACT:
An ultrasound high velocity flow measurement apparatus uses cross-correlation between consecutive echoes of coded pulses which are matched filtered at the receiver to determine velocity profiles of flowing blood. Because coded pulses are used, the interval between two pulses can be made arbitrarily small, effectively removing the peak velocity limitation.
