Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0029] Application overview

[0030] Coronary Arteriography (CAG) is the gold standard for the diagnosis of coronary artery disease. It can clarify the location, degree and scope of lesions, and has the advantage of high accuracy of detection results. However, CAG is an invasive examination. Coronary Computed Tomography Anglography (Coronary Computed Tomography Anglography, CCTA), as a cardiac tomography technique, has become the main non-invasive imaging tool for the diagnosis of coronary arte...

Abstract

The invention provides a coronary artery image classification method and device. The method comprises the steps of determining a first sub-tree where a convolution branch starting from a tail end node of a left trunk is located in a coronary artery image; determining a first point on the first branch and a second point on the second branch starting from a first bifurcation node on the first subtree; determining a first vector formed by the first point and a preset point and a second vector formed by the second point and the preset point; determining a first included angle between the first vector and a preset vector and a second included angle between the second vector and the preset vector; and determining a convolution branch based on the first included angle and the second included angle. In addition, the coronary artery image classification method provided by the invention can also realize the identification of the right coronary artery main branch. According to the technical scheme of the invention, the method can improve the accuracy of the coronary artery image classification result, and is higher in robustness.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a coronary image classification method and device. Background technique [0002] Cardiovascular disease is more common in middle-aged and elderly people, but in recent years, the incidence of cardiovascular disease has a tendency to become younger, which seriously endangers people's health. Therefore, it is very important to accurately identify the various branches of the cardiovascular system and determine the location of the lesion for the diagnosis and treatment of cardiovascular diseases. [0003] Due to the many branches of the cardiovascular system, the current recognition methods or classification methods for each branch of the cardiovascular system have problems of low accuracy and poor robustness. Contents of the invention [0004] In view of this, the embodiments of the present application provide a coronary artery image classification method and d...
