Abstract

Provided are a method of displaying a Doppler image and an ultrasound diagnosis apparatus for performing the method. The method includes: obtaining a first Doppler signal where clutter filtering corresponding to each of a plurality of pixels is not performed and a second Doppler signal where clutter filtering corresponding to each of the plurality of pixels is performed; determining a first motion score indicating a degree of flash artifact occurrence by using velocity information of the first Doppler signal; determining a first weight for suppressing flash artifacts of each pixel based on the first motion score and a velocity difference value between the first Doppler signal and the second Doppler signal; generating a first Doppler image of the object by applying the first weight to the second Doppler signal of each pixel; and displaying the first Doppler image of the object.
