Problems solved by technology

However, since CTA images contain multiple vascular branches, and each vascular branch contains multiple vascular stenosis sites, doctors detect vascular stenosis sites visually, and it is very easy for vascular stenosis sites to be missed, resulting in inaccurate diagnosis

Abstract

The invention discloses a vascular stenosis detection method and device and a computer readable medium, and the method comprises the steps: firstly carrying out vascular stenosis site detection on a blood vessel straightening reconstruction image, and generating a vascular stenosis list; obtaining an adding instruction of the blood vessel stenosis site; then responding to the adding instruction, and adding the vascular stenosis site to the vascular stenosis list; and finally, for any blood vessel stenosis site in the blood vessel stenosis list, determining a stenosis lumen diameter and a reference lumen diameter corresponding to the blood vessel stenosis site, and determining the stenosis degree of the blood vessel lumen based on the stenosis lumen diameter and the reference lumen diameter. Therefore, the blood vessel stenosis site of the blood vessel lumen can be effectively detected, the problem of omission of blood vessel stenosis site detection is avoided, and the accuracy of blood vessel stenosis site detection is improved.

Description

technical field [0001] The present invention relates to the technical field of user intelligence, in particular to a method, device and computer-readable medium for detecting vascular stenosis. Background technique [0002] Computed tomography angiography (Computer Aided Translation, abbreviated CTA) is an image of the developed arterial lumen generated by helical scanning of the region of interest after intravenous injection of contrast agent. Common CTA images include coronary artery CTA images, cerebrovascular CTA images, carotid artery CTA images, pulmonary artery CTA images, and aortic CTA images. The combination of CTA image and image reconstruction technology can completely restore the spatial structure of arterial vessels, so that vascular lesions caused by vascular stenosis can be effectively diagnosed. [0003] Vascular reconstruction can generate multiple image sequences, including but not limited to VR volume rendering images, maximum density projection images, ...
