ULTRASONIC DIAGNOSTIC APPARATUS
First Claim
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.

Abstract
According to one embodiment, based on a reception signal, the Doppler signal generation unit generates a first Doppler signal attributed to motion of a living body in a ROI and a second Doppler signal attributed to slower motion. The velocity display scale determination unit determines first and second velocity display scales based on velocity distribution ranges for the first and second Doppler signals, respectively. The image generation unit generates first and second Doppler images based on the first and second Doppler signals, respectively. The display unit displays the first and second Doppler images with the first and second velocity display scales, respectively.
