Abstract

Embodiments of the present application disclose a method and system for intracranial artery vascular image segmentation. The scheme includes receiving three-dimensional CTA images; based on three-dimensional CTA images, seed points are selected and the gray scale range is determined. Three-dimensional CTA image is binarized to obtain binary image, and the binary image of intracranial artery regionis enhanced by vascular enhancement filter to obtain enhanced image. If there are seed points in three-dimensional CTA images, three-dimensional intracranial arterial images are segmented by region growing method based on enhancement images. If there are no seed points in the three-dimensional CTA image, the three-dimensional intracranial artery image is segmented by interval binary segmentationbased on the enhancement image. This scheme makes the edge of the segmented 3D intracranial artery image clear and saves the filtering time, thus realizing the accurate segmentation of the 3D CTA image of intracranial artery.

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 Emission computed tomography (PET), CTA and other medical imaging technologies have been widely used in clinical diagnosis. CTA is an angiographic examination using computer-assisted tomography (CT) technology, which can explore all arteries and veins in the body, including blood vessels in the heart, brain, lungs, kidneys, and limbs. Since Rontgen discovered X-rays, people can use X-ray perspective equipment to detect information inside objects. Its technology mainly makes blood less permeable to X-rays...
