Image processing system and method for controlling gains for color flow images
First Claim
Patent Images
1. An image processing system, comprising:
- an image forming unit for forming a number of color flow images based on input image signals;
a reference image selecting unit for selecting a reference image for gain control among the color flow images;
a gain control value calculating unit for calculating a gain control value based on the reference image; and
a gain control unit for controlling gains for the color flow images based on the gain control value,wherein the gain control value calculating unit forms a contour of a blood vessel by the following steps;
extracting edge data from the reference image;
performing morphological operations on the edge data;
performing a connected-component labeling operation;
detecting a seed point in the edge data;
extracting blood vessel edge data from the edge data based on the seed point; and
forming the contour of the blood vessel based on the blood vessel edge data.
