Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Such as figure 1 As shown, the blood vessel labeling method in the embodiment of the present invention includes the following steps:

[0028] S1, importing a CT image to be labeled.

[0029] Wherein, the imported CT images include plain scan CTA images and enhanced CTA images. A CT image includes a blood vessel area, for example, a coronary blood vessel, which does not include a bone area, or a head and neck blood vessel, which includes a bone area. ...

Abstract

The invention provides a blood vessel labeling method and device. The method comprises the following steps: importing a CT image to be labeled; selecting a plurality of seed points in a region of interest of the CT image, and obtaining a blood vessel region to be labeled by using a region growing method; carrying out blood vessel editing on the blood vessel area to be labeled to obtain a blood vessel labeling result; generating a corresponding three-dimensional grid model according to the blood vessel labeling result; and reprojecting the three-dimensional grid model to the original CT image to obtain a blood vessel contour. According to the invention, the blood vessel on the CT image can be accurately and effectively labeled.

Description

technical field [0001] The invention relates to the technical field of image processing and analysis, in particular to a blood vessel marking method and a head and neck blood vessel marking device. Background technique [0002] Stroke, also known as cerebrovascular accident, is a disease of cerebral blood circulation disorder, and its fatality rate is second only to heart diseases and higher than cancer. At present, the incidence and mortality of stroke in my country are still on the rise, and the mortality rate of the elderly after stroke is twice that of the young. Stroke is divided into ischemic stroke and hemorrhagic stroke, of which ischemic stroke accounts for about 80%. One of the main causes of ischemic stroke is atherosclerotic vulnerable plaques in the head and carotid arteries leading to lumen stenosis and hemodynamic changes. At the same time, the carotid artery, as the upstream blood vessel of the intracranial artery, is the main blood supply artery of the cer...
