Abstract

The embodiment of the present application discloses a method and system for segmenting an intracranial artery image. The solution includes: receiving a 3D CTA image; selecting seed points and determining the required gray scale range based on the 3D CTA image; binarizing the 3D CTA image to obtain a binary image; The binary image of the 3D CTA image is enhanced to obtain an enhanced map; if there are seed points in the 3D CTA image, based on the enhanced map, the 3D intracranial artery image is segmented by the region growing method; if there is no seed point in the 3D CTA image, based on the enhanced map, by Segmentation of three-dimensional intracranial arterial images by interval binary segmentation. This scheme makes the edge of the segmented three-dimensional intracranial arterial image clear, saves time-consuming filtering, and thus realizes accurate segmentation of the intracranial arterial image of the three-dimensional CTA image.

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...
