Abstract

The invention discloses a blood vessel segmentation method and device. The method includes: using sample image training to obtain a blood vessel central line average model; aligning a to-be-segmented image with the template image of a sample image; mapping the blood vessel central line average model to the to-be-segmented image; regulating the blood vessel central line average model on the basis of the priori knowledge of the to-be-segmented image to obtain the blood vessel central line of the to-be-segmented image; performing blood vessel segmentation on the to-be-segmented image on the basis of the blood vessel central line of the to-be-segmented image. By the method, blood vessel segmentation problems can be well solved, blood vessel segmentation is clean, and segmentation failure caused by the fact that the bone is segmented.

Description

technical field [0001] The invention relates to the field of medical images, in particular to blood vessel segmentation. Background technique [0002] Vascular imaging techniques include computed tomography angiography (CTA), magnetic resonance angiography (MRA), etc., which are very important techniques that can help doctors diagnose various diseases of blood vessels, such as calcification, stenosis, aneurysm, etc. In the process of vascular imaging, three-dimensional images are mainly obtained, which not only show the blood vessels but also include other tissues around the blood vessels (such as fat, muscle, bone, etc.), which cannot give doctors an intuitive feeling. Therefore, it is very important to extract blood vessels from the overall 3D image and display the shape of blood vessels with 3D display technology for the diagnosis of vascular diseases. [0003] The techniques of CTA blood vessel extraction can be mainly divided into two categories: model method and non-m...
