Abstract

The invention discloses an extraction method of a blood vessel centerline. The extraction method comprises the following steps of: on the basis of a medical image, extracting blood vessels and a plurality of connected domains; screening the plurality of connected domains, and obtaining n blood vessel connected domains; on the basis of the direction coordinate value of each blood vessel connected domain, marking the n blood vessel connected domains in a descending order; according to a descending order marking sequence, connecting centerlines between the (m+1)th connected domain and the mth connected domain in sequence, and enabling the centerlines to grow until a centerline among the n blood vessel connected domains finishes growing; and on the basis of the centerline, extracting the blood vessels. By use of the extraction method, which is provided by the invention, of the blood vessel centerline, the blood vessels which tightly cling to a bone area can be extracted, and an integral blood vessel tissue is obtained.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of medical image processing, in particular to a method for extracting a blood vessel centerline. [0003] 【Background technique】 [0004] Vascular imaging techniques include CT angiography (CTA, CT angiography), magnetic resonance angiography (Magnetic Resonance Angiography, MRA), and MR non-contrast imaging, which can help doctors diagnose various diseases of blood vessels, such as calcification, stenosis, aneurysm , dura mater, etc. Vascular images obtained by vascular imaging technology are mainly three-dimensional images, which cannot give doctors an intuitive feeling. Therefore, it is necessary to extract blood vessels from medical images and display the shape of blood vessels with three-dimensional display technology to better assist doctors in analyzing lesions, improve the accuracy and scientificity of medical diagnosis, and help formulate optimal treatment plans and surgical planning. , which is of ...
