Abstract

The invention is suitable for the technical field of medical image processing, and provides a vascular tree extraction method, device and equipment and a storage medium. The method comprises the steps that a discontinuous vascular ridge line acts as an initialized vascular curve; in the iterative process of the vascular curve, the tentative points of a target curve are acquired by using the endpoints of the vascular curve after iteration, and the candidate points of the target curve are determined from the tentative points according to an inclined angle cosine threshold; the fusion points of the target curve are determined in the candidate points by calculating the minimum value of the inclined angle of a connection vector and the tangent vector of each candidate point; and fusion connection of the endpoints of the current vascular curve and one side curve of the fusion points of the target curve is performed so as to form a new vascular curve. The effectiveness and the accuracy of vascular tree extraction can be enhanced so as to have important clinical significance for the cardiovascular interventional operation.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, and in particular relates to a method, device, equipment and storage medium for extracting a vascular tree. Background technique [0002] Coronary heart disease is a serious threat to human health. With the high development of CT (Computed Tomography) imaging and angiography technology, medical image post-processing technology plays an increasingly important role in assisting doctors in diagnosis and treatment. . When the imaging department of a hospital uses CTA (CT angiography) to diagnose coronary heart disease, the computer-aided diagnosis and treatment software bundled with CT equipment can help doctors judge vascular injury. However, problems such as low diagnostic efficiency and missed diagnosis are still unavoidable. Contents of the invention [0003] The object of the present invention is to provide a vascular tree extraction method, device, equipment and storage medi...
