Blood vessel structure image plane atlas construction method

Abstract

The invention discloses a blood vessel structure image plane atlas construction method, which comprises the following steps: 1) collecting a two-dimensional or three-dimensional medical image containing a local blood vessel structure, and if the original image is a blood vessel two-dimensional projection image, distinguishing and labeling arteries and veins; 2) extracting a blood vessel region byusing an image segmentation algorithm, and constructing blood vessel three-dimensional volume data; 3) extracting a skeleton line of the blood vessel region by using a thinning algorithm; 4) finding out a branch point and an end point of the skeleton line; 5) constructing a triangular curved surface of the blood vessel; 6) closing end points of the triangular network to form a discrete curved surface; and 7) mapping the discrete curved surface to a plane to form a discrete curved surface, and keeping all sides of the triangle not to be overlapped to obtain a planar two-dimensional image of thevascular structure. According to the invention, the three-dimensional structure of the blood vessel can be expanded to a two-dimensional plane on the premise of keeping the connection relationship between the blood vessels and the length information of the blood vessel, so that the hemodynamic characteristics of a local blood vessel area can be observed and analyzed conveniently.

Description

technical field [0001] The invention relates to the application of computer-aided disease diagnosis, in particular to a method for constructing a planar atlas of vascular structure images. Background technique [0002] The invention mainly plays an auxiliary role in blood flow characteristic analysis and blood vessel robot navigation. [0003] figure 1 In terms of the analysis of the blood flow characteristics shown: since cardiovascular diseases are often reflected in the dynamics of blood flow in the early stage of the disease, if the vascular characteristics of the local area of ​​the body (such as the human eye), especially the morphology and Analysis of fluid dynamics will help in the early diagnosis and treatment of cardiovascular diseases. Clinical researchers have proposed a method to diagnose diabetic retinopathy by using color Doppler ultrasound to measure the intersection of the posterior pole of the eyeball and the dark area of ​​the optic nerve to obtain the C...
