1. An ultrasonic diagnostic apparatus comprising:

  • an ultrasonic probe;

    an ultrasonic transmission unit configured to transmit an ultrasonic wave to an object via the ultrasonic probe;

    an ultrasonic reception unit configured to generate a reception signal based on a reflected wave of the ultrasonic wave;

    a Doppler signal generation unit configured to generate a first Doppler signal and a second Doppler signal based on the reception signal, wherein the first Doppler signal is attributed to first motion which is motion of a living body in a region of interest in a predetermined azimuth direction, and wherein the second Doppler signal is attributed to second motion slower than the first motion;

    a velocity display scale determination unit configured to determine a first velocity display scale based on a velocity distribution range for the first Doppler signal and determine a second velocity display scale based on a velocity distribution range for the second Doppler signal;

    an image generation unit configured to generate a first Doppler image based on the first Doppler signal and generate a second Doppler image based on the second Doppler signal; and

    a display unit configured to display the first Doppler image with the first velocity display scale and display the second Doppler image with the second velocity display scale.
