Abstract

The invention provides a three-dimensional reconstruction method and device for coronary blood vessels, electronic equipment and a storage medium, and the method comprises the steps: extracting an IVUS blood vessel inner contour based on an IVUS sequence; determining blood vessel geometric parameters based on CAG images at different angles at the same moment in a coronary artery angiography CAG sequence, the frame number corresponding to the IVUS at the key point position and the IVUS retracement rate, and performing three-dimensional blood vessel reconstruction based on the blood vessel geometric parameters; and positioning and orienting the IVUS sequence on the center line of the reconstructed three-dimensional blood vessel based on the inner contour of the IVUS blood vessel to obtain a fused three-dimensional coronary blood vessel model.

Description

technical field [0001] The present application relates to but not limited to the field of computer technology, and in particular relates to a three-dimensional reconstruction method, device, electronic equipment and storage medium of coronary vessels. Background technique [0002] Coronary angiography (CAG) is an objective diagnosis of coronary artery structure and vascular stenosis, and can obtain a three-dimensional vascular skeleton by reconstructing three-dimensional blood vessels. Intravascular Ultrasound (IVUS) can not only accurately measure parameters such as the diameter and area of ​​the vascular lumen, but also detect early coronary atherosclerotic plaques, and then analyze the eccentricity, wall thickness and composition of the plaques. content was tested. [0003] In related technologies, IVUS data are fused with the CAG vessel reconstruction. However, due to the shooting angle problem, the vessel reconstructed from the CAG image is not the length of the real v...
