Method and System for Automatic Calculation of Coronary Syntax Score Based on Sequence Angiography

Abstract

The coronary SYNTAX score automatic calculation method and system based on sequence angiography can automatically complete the identification of coronary anatomy, the detection of coronary stenosis and the judgment of adverse coronary symptoms, and finally automatically complete the coronary SYNTAX score, which can assist in accurately grasping the patient Coronary artery lesions, and efficiently complete the diagnosis process of the patient's condition. The method includes: (1) extracting a relatively complete coronary vessel structure from the key frame of the sequence angiography image; (2) identifying the anatomical structure of the coronary vessel structure, and retaining the corresponding coronary artery anatomical pattern diagram; (3) Guided by the known coronary segment on the key frame, the tracking of the corresponding coronary segment on the sequence angiography image is realized; (4) Stenotic lesion detection is performed on the sequential coronary structure; (5) Based on the detected stenotic lesions, it is judged whether there are adverse symptoms; (6) According to the SYNTAX scoring criteria, the SYNTAX score is automatically calculated.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a method for automatically calculating coronary SYNTAX scores based on sequence angiography, and a system for automatically calculating coronary SYNTAX scores based on sequence angiography. Background technique [0002] Insufficient blood supply of the coronary arteries attached to the surface of the heart can lead to myocardial ischemia and hypoxia, clinically causing symptoms such as chest pain and tightness, also known as coronary heart disease. As we all know, coronary heart disease is an important cause of death in the world. Clinically, coronary insufficiency is mostly caused by stenosis of the vascular lumen, so the most conventional way of diagnosing coronary heart disease is to judge whether there is ischemia in the coronary arteries. Clinically, serial coronary angiography is the most direct and objective method for detecting blood vessels, and it is a...

Problems solved by technology

However, due to the injection of contrast medium, artificial judgment of coronary stenosis is often affected by the temporary blockage of contrast medium in the image, resulting in wrong judgment of stenosis

At the same time, due to the principle of fluoroscopy imaging, there will be more overlapping of blood vessels on the two-dimensional angiography image, and it is easy to form structures such as rings and pseudo bifurcation points, resulting in difficulties in artificially corresponding coronary segments

In addition, the analysis of whether coronary stenosis is a given adverse condition is complicated

Due to the above reasons, it is difficult to guarantee the accuracy of SYNTAX scoring for physicians who are inexperienced in coronary angiography reading. Even for experienced physicians, the scoring process is also time-consuming and difficult to be widely used
