Claim:
1. A method of forming a color Doppler image in an ultrasound diagnostic system, comprising: scanning a first set of scan lines at a full scan region to detect a moving object; determining a second set of scan lines, each of which passes the moving object from among the first set of scan lines, wherein the second set of scan lines includes a first scan line passing a first position in the moving object and a second scan line passing a second position in the moving object; and scanning the second set of scan lines and a predetermined number of scan lines neighboring to the second set of scan lines, exclusive of other scan lines, wherein the scanning the second set of scan lines comprises scanning the first scan line up to a first depth of the moving object at the first position and scanning the second scan line up to a second depth of the moving object at the second position, to form a first color Doppler image, the first depth and the second depth being different to each other depending on the first position and the second position in the moving object.
