Embodiment 1

[0065] Such as figure 1 As shown, in order to solve the above problems, the present application provides a method for extracting a blood vessel centerline from a two-dimensional coronary angiography image, including:

[0066] S500, extracting at least one blood vessel path line from the coronary angiography two-dimensional image;

[0067] S600. Select a blood vessel path line as the blood vessel centerline.

Embodiment 2

[0069] Such as figure 2 As shown, in order to solve the above problems, the present application provides a method for extracting a blood vessel centerline from a two-dimensional coronary angiography image, including:

[0070] S100, reading a two-dimensional coronary angiography image;

[0071] S200, acquiring a blood vessel segment of interest;

[0072] S300, pick up the starting point and the ending point of the vessel segment of interest;

[0073] S400, segment the local blood vessel region map corresponding to the starting point and the ending point from the two-dimensional coronary angiography image, such as image 3 shown, including:

[0074] S410, picking at least one seed point of the vessel segment of interest;

[0075] S420, respectively segment the two-dimensional contrast images between two adjacent points of the start point, the seed point, and the end point to obtain at least two local blood vessel region maps; since the two-dimensional contrast images are di...

Embodiment 3

[0086] Such as Figure 7 As shown, the present application provides a device for extracting a blood vessel centerline from a two-dimensional coronary angiography image, including: a sequentially connected blood vessel path unit 100 and a blood vessel centerline extraction unit 200; At least one blood vessel path line is extracted from the arterial two-dimensional angiography image; the blood vessel centerline extraction unit 200 is configured to select one of the blood vessel path lines sent by the blood vessel path unit 100 as the blood vessel centerline.

[0087] Such as Figure 8 As shown, in one embodiment of the present application, it also includes: an image segmentation unit 300 connected to the blood vessel path unit 100; the image segmentation unit 300 is used to segment the starting point and the end point corresponding to the two-dimensional coronary angiography image. The local blood vessel area map, or segment the two-dimensional contrast image between two adjace...

Abstract

The invention provides a method, device and system for extracting a blood vessel center line from a coronary artery two-dimensional contrast image. The method for extracting the blood vessel center line from the coronary artery two-dimensional contrast image comprises the steps of extracting at least one blood vessel path line from the coronary artery two-dimensional contrast image; and selectingone blood vessel path line as the blood vessel center line. At least one blood vessel path line is extracted from the coronary artery two-dimensional radiography image, then the blood vessel center line is obtained according to the blood vessel path line, a new thought is provided for technicians, and the method has the advantages of being rapid in extraction, low in difficulty and high in accuracy.

Description

technical field [0001] The invention relates to the technical field of coronary artery medicine, in particular to a method, a device, a coronary artery analysis system and a computer storage medium for extracting a blood vessel centerline from a two-dimensional coronary angiography image. Background technique [0002] The deposition of lipids and sugars in human blood on the blood vessel wall will form plaques on the blood vessel wall, which in turn will lead to vascular stenosis; especially the vascular stenosis near the coronary artery of the heart will lead to insufficient blood supply to the myocardium and induce coronary heart disease , angina pectoris and other diseases pose a serious threat to human health. According to statistics, there are about 11 million patients with coronary heart disease in my country, and the number of patients treated with cardiovascular interventional surgery is increasing by more than 10% every year. [0003] Conventional medical detection...
