METHOD, DEVICE, AND SYSTEM FOR THREE-DIMENSIONAL MODELING OF BLOOD VESSEL HAVING STENOSIS LESION SEGMENT

Document Type and Number:

WIPO Patent Application WO/2021/097820

Kind Code:

A1

Abstract:

A method, a device, and a system for three-dimensional modeling of a blood vessel having a stenosis lesion segment. The method comprises: extracting a blood vessel center line from each of two-dimensional coronary angiographic images in at least two postures along a direction from the entrance of the coronary artery to the end of the coronary artery (S500); obtaining straightened blood vessel images according to the two-dimensional coronary angiographic images and the blood vessel center lines (S600); obtaining straightened blood vessel contour lines according to the straightened blood vessel center lines and the straightened blood vessel images (S700); obtaining geometric information of the straightened blood vessel (S800); and performing three-dimensional modeling according to the geometric information, the center lines, and the contour lines, to obtain a three-dimensional model of the blood vessel having the stenosis lesion segment (S900). The stenosis lesion segment is displayed to a patient and a doctor in a three-dimensional manner by means of the three-dimensional blood vessel model, is more vivid, and displays all angles of the stenosis lesion, thereby reducing a two-dimensional angiographic image capture angle influencing an assessment of the coronary artery stenosis, and enabling accurate determination of the stenosis lesion segment of the blood vessel.
