Method and apparatus for acquiring contour line of blood vessel according to centerline of blood vessel

Abstract

The present disclosure provides a method and an apparatus for acquiring a contour line of a blood vessel according to a centerline of the blood vessel. The method comprises: extracting a centerline of a blood vessel according to a two-dimensional coronary artery angiogram image (S100); obtaining an image of a straightened blood vessel according to the centerline of the blood vessel (S200); setting a threshold Dthreshold for a diameter of the blood vessel on the image of the straightened blood vessel (S300); generating a preset contour line of the blood vessel on both sides of a centerline of the straightened blood vessel according to the Dthreshold (S400); making the preset contour line of the blood vessel step-by-step approach the centerline of the straightened blood vessel to acquire a contour line of the straightened blood vessel (S500); projecting the contour line of the straightened blood vessel back onto the image of the centerline of the blood vessel to obtain a contour line of the blood vessel (S600).
