1. Ultrasonic diagnostic apparatus for providing Doppler information concerning flow velocities comprising:

  • means for acquiring Doppler signals from a region of a body;

    means for accessing said Doppler signals to produce spectral line data representing frequency or velocity for continuous display of a succession of spectral lines during the continuation of Doppler signal acquisition;

    means for analyzing the data of a plurality of said spectral lines to determine a threshold level;

    means for utilizing said threshold level and said spectral line data of a first successive spectral line to identify a peak velocity value in said first successive spectral line prior to the display of said first successive spectral line; and

    means for displaying said first successive spectral line and its identified peak velocity value prior to the display of a second successive spectral line.
