Ultrasound system and method for performing vessel labeling
View Patent ↗There are disclosed embodiments for an ultrasound system for performing vessel labeling. The ultrasound system comprises: an ultrasound data acquisition unit configured to transmit an ultrasound signal to a target object including vessels, receive an ultrasound echo signal reflected from the target object and form ultrasound data corresponding to the target object; a volume data forming unit configured to form volume data based on the ultrasound data; and a processor configured to form a 3-dimensional ultrasound image based on the volume data, perform vessel segmentation on the 3-dimensional ultrasound image to provide at least one segmented image including at least one segmented vessel, detect at least one vessel junction from the at least one segmented vessel and perform vessel labeling on the at least one segmented image based on the detected at least one vessel junction.
1. An ultrasound system, comprising:
an ultrasound data acquisition unit configured to transmit an ultrasound signal to a target object including vessels, receive an ultrasound echo signal reflected from the target object and form ultrasound data corresponding to the target object;
a volume data forming unit configured to form volume data based on the ultrasound data; and
a processor configured to form a 3-dimensional ultrasound image based on the volume data, perform edge detection on the 3-dimensional ultrasound image to detect edges of the vessels, set a plurality of slices on the edge-detected 3-dimensional ultrasound image, calculate differences in location between edges of the vessels on each adjacent pair of the slices, compare the calculated location differences with a predetermined threshold and connect edges based on a result of the comparison, perform vessel segmentation of the vessels based on the connected edges to form segmented vessels, detect at least one vessel junction from the segmented vessels and perform vessel labeling on the segmented vessels based on the detected at least one vessel junction.
2. The ultrasound system of claim 1 , wherein the processor is configured to perform the vessel labeling on the segmented vessels with at least one of a number, text and color.
3. A method of performing segmentation of vessels, comprising steps of:
transmitting an ultrasound signal to a target object including vessels and receiving an ultrasound echo signal reflected from the target object to thereby form ultrasound data corresponding to the target object;
forming volume data based on the ultrasound data;
forming a 3-dimensional ultrasound image based on the volume data;
performing edge detection on the 3-dimensional ultrasound image to detect edges of the vessels;

comparing the calculated location differences with a predetermined threshold and connecting edges based on a result of the comparison;
performing vessel segmentation of the vessels based on the connected edges to form segmented vessels;
detecting at least one vessel junction from the segmented vessels; and
performing vessel labeling on the segmented vessels based on the detected at least one vessel junction.
4. The method of claim 3 , wherein the step of performing vessel labeling, comprises the step of:
performing the vessel labeling on the segmented vessels with at least one of number, text and color.
