Problems solved by technology

However, both methods have obvious deficiencies. Coronary tracking based on deep network prediction will cause the entire vessel branch to be lost due to incorrect prediction of coronary bifurcation points; 3D skeletons based on coronary mask extraction often rely too much on Accuracy of coronary artery segmentation, unreliable centerline extraction in the presence of vascular adhesions or when veins are misidentified as coronary arteries
These unstable factors may affect the follow-up doctor's diagnosis of the disease

Embodiment Construction

[0022] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0023] The core of the present invention is to propose a coronary artery centerline generation algorithm based on two-way coronary artery tracking. In the coronary artery centerline detection task, the coronary artery centerline tree is generated from top to bottom, and the coronary artery center is completed from bottom to top. The branches of the line tree and the vascular adhesions were removed at the same time to extract a more ...

Abstract

The invention provides a coronary artery center line generation method and device based on bidirectional coronary artery blood vessel tracking. The method comprises the steps that according to an input coronary artery mask, blood vessel starting points, located at the aortic sinus, of coronary artery blood vessels and all tail end points in a connected domain in the mask where all the starting points are located are extracted; coronary artery center lines are extracted by tracking coronary artery blood vessels from top to bottom from a starting point, and a coronary artery center line tree isconstructed; coronary vessels are tracked from bottom to top from the tail end point, and a coronary center line tree is complemented; removing blood vessel adhesion and vein center lines, and combining all extracted coronary artery center line trees to obtain a complete coronary artery center line.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating a coronary centerline based on bidirectional coronary vessel tracking. Background technique [0002] Coronary artery centerline extraction in cardiac CT (CCTA) images is a prerequisite for the assessment of stenosis and atherosclerotic plaque. The existing methods can be roughly divided into two categories: predictive tracking algorithm based on deep network; 3D skeleton extraction algorithm based on coronary mask. However, both methods have obvious deficiencies. Coronary tracking based on deep network prediction will lead to the loss of entire vessel branches due to incorrect prediction of coronary bifurcation points; 3D skeletons based on coronary mask extraction are often overly dependent on Accuracy of coronary artery segmentation, centerline extraction is not reliable in the presence of vascular adhesions or when veins are misidentified ...
