Abstract

The embodiment of the present application discloses a method and system for segmenting an intracranial artery image. The scheme includes: selecting seed points and determining the gray scale range in the three-dimensional DSA image; based on the selected seed points and determining the gray scale range, segmenting the intracranial artery image by using the region growing method. This scheme provides a segmentation method of intracranial arterial blood vessel image with less interference of segmentation noise and higher efficiency of segmentation operation.

Description

technical field [0001] The present application relates to the field of medical imaging, in particular to a method and system for segmenting images of intracranial arteries. Background technique [0002] With the continuous progress and development of modern medical imaging equipment, the development of medical imaging technology and computer graphics has brought great changes to medicine. Computed tomography (CT), nuclear magnetic resonance (MRI), ultrasound (US), positron Medical imaging techniques such as emission computed tomography (PET) and digital subtraction angiography (Digital Subtraction Angiography, DSA) have been widely used in clinical diagnosis. DSA is a new X-ray imaging system. It is the product of the combination of conventional angiography and computer image processing technology. It can also be said that the image of bone and soft tissue on the angiogram is eliminated by computer. A photographic technique that highlights blood vessels. [0003] The basic...
