Abstract

The present application discloses a method and a device for extracting the central line of head and neck blood vessels. The method includes: obtaining blood vessel segmentation results and blood vessel heat map results according to cranial vessel CTA images; inputting blood vessel skeleton lines extracted based on the blood vessel segmentation results into a preset network model to classify and name blood vessels, and obtaining blood vessel starting and ending point data; The blood vessel starting and ending point data and the blood vessel heat map result are used to extract the centerline of the head and neck blood vessels. The present application solves the technical problem of low accuracy in extracting the centerline of blood vessels in the related art. Through this application, the purpose of extracting the centerline of the blood vessel by combining the local detail information and the global structure information of the head and neck blood vessels is achieved, thereby achieving the technical effect of improving the accuracy of the centerline extraction of the head and neck blood vessels.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a method and device for extracting the centerline of head and neck vessels. 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 cerebral...
