1. An ultrasonic wave imaging apparatus comprising:

  • velocity distribution calculating means which calculates the velocity distribution of an echo source based on the Doppler shift of an echo received from a repetitively transmitted ultrasonic wave;

    profile calculating means which calculates the profile of said velocity distribution, reflection correcting means which corrects the reflection of said profile;

    maximum value detecting means which detects the maximum value of the velocity in said corrected profile;

    repetition frequency adjusting means which adjusts the repetition frequency of said ultrasonic wave based on said maximum value; and

    display means which displays said velocity distribution as an image.
