Abstract

The embodiment of the invention provides an intracranial aneurysm image segmentation method and system, and the method comprises the steps: intercepting a local three-dimensional image from a to-be-segmented intracranial aneurysm-carrying blood vessel image; Acquiring a tree-shaped central line of the local three-dimensional image, and calculating the central line and the radius of the intracranial tumor-carrying blood vessel image; And segmenting the intracranial aneurysm image based on the center line and the radius of the intracranial aneurysm-carrying blood vessel image. The intracranial aneurysm image segmentation method is good in segmentation precision and high in segmentation efficiency, and automatic segmentation of the intracranial aneurysm image is achieved.

Description

technical field [0001] This specification relates to the field of medical imaging, in particular to a method and system for segmenting intracranial aneurysm images. Background technique [0002] Intracranial aneurysm is a tumor-like protrusion on the arterial wall caused by local abnormal expansion of the intracranial artery lumen, and is a common vascular disease. According to reports, the prevalence of unruptured intracranial aneurysms in Chinese adults is as high as 7%, and rupture can cause subarachnoid hemorrhage, which can lead to severe disability or death. According to the data from the National Bureau of Statistics in 2014, acute cerebrovascular disease is the second leading cause of death in my country. Aneurysmal subarachnoid hemorrhage is the most common acute cerebrovascular disease after ischemic stroke and hypertensive cerebral hemorrhage. The death and disability rate is as high as 64%, and about 15% of patients die before hospital. Regions with different ec...
