Classification: CPC A  G | IPC A

Claim 13:
14. An ultrasonic imaging system, comprising:
a display;
a probe configured to transmit an ultrasonic beam to a scan target;
a receiving circuit configured to receive an echo signal of the ultrasonic beam;
a beam-former configured to perform a beam-forming on the echo signal to obtain an ultrasonic signal; and
an image processor configured to:
obtain blood flow velocity vectors in the scan target according to the ultrasonic signal;
obtain an ultrasonic image of at least a portion of the scan target according to the ultrasonic signal;
present the ultrasonic image on the display;
obtain an indication of a sampling box on the ultrasonic image;
extract multiple blood flow velocity directions from the blood flow velocity vectors associated with the sampling box;
calculate a variance or a standard deviation of the extracted multiple blood flow velocity directions;
segment an area of the ultrasonic image associated with the sampling box into a plurality of non-overlapping regions according to the variance or the standard deviation for each region; and
construct an icon model comprising a plurality of blocks respectively corresponding to the plurality of non-overlapping regions, wherein each block indicates the variance or the standard deviation of the extracted multiple blood flow velocity directions for the respective region;

wherein the display is configured to comparatively present the icon model simultaneously with the ultrasonic image.
