1. An ultrasound imaging apparatus comprising:
a probe configured to irradiate an ultrasound signal to an object and receive an ultrasound echo signal reflected from the object;
an image processor configured to obtain a color Doppler signal from which a clutter signal has been completely or partially removed by filtering the ultrasound echo signal, obtain a plurality of consecutive Doppler image frames based on the color Doppler signal and generate a Doppler image based on the plurality of consecutive Doppler image frames;
a display configured to output the Doppler image; and
a controller configured to calculate a flash artifact score of each of the plurality of consecutive Doppler image frames based on the ultrasound echo signal, generate a timeline corresponding to the plurality of consecutive Doppler image frames and control the display so that the flash artifact score of each of the plurality of consecutive Doppler image frames appear on the timeline,
wherein the controller is configured to determine whether the probe is scanning the object and control the display to display an indicator representing a time point at which the probe starts to scan the object on the timeline.
