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.

Abstract
Embodiments for adaptively forming color Doppler images in an ultrasound diagnostic system are disclosed. A method of forming a color Doppler image in an ultrasound diagnostic system comprises: scanning a first set of scan lines set at a full scan region to detect at least one scan line that passes a moving object in the full scan region among the first set of scan lines; setting a second set of scan lines based on the detected scan lines; and scanning the second set of scan lines to form a first color Doppler image.

8. An ultrasound diagnostic system, comprising:
-
a probe configured to transmit ultrasound signals into a target object and receive echo signals reflected from the target object to thereby output receive signals, the receive signals including first receive signals obtained by scanning a first set of scan lines at a full scan region; and an image processor configured to; detect a moving object based on the first receive signals, and determine a second set of scan lines, each of which passes the moving object among the first set of scan lines based on the first receive signals, 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, wherein the probe is further configured to scan 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, and wherein the probe, when scanning the second set of scan lines, is further configured to scan the first scan line up to a first depth of the moving object at the first position and scan 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. - View Dependent Claims (9, 10, 11, 12, 13, 14)
