Abstract

The present invention provides a vessel extraction method, device and system. The method comprises the following steps: obtaining an image comprising vessel information; determining an interest area in the image; performing statistics of the gray value of the interest area; according to the gray value, setting a growth parameter; based on Fast Marching, growing main portion vessels; regulating the growth parameter, and tracking vessel branches; and based on the main vessels and the vessel branches, extracting a vessel area. The vessel extraction method can rapidly and completely extract the main vessels and the vessel branches.

Description

【Technical field】 [0001] The invention relates to the field of medical image processing, in particular to a method, device and system for extracting blood vessels. 【Background technique】 [0002] The portal venous system is an important part of the human circulatory system. The automatic extraction of portal vein vessels can not only help doctors to quickly diagnose portal hypertension and other related diseases, but also provide doctors with a more intuitive view of the system anatomy, which is convenient for surgical planning. [0003] The existing portal vein extraction is mainly limited to the extraction of intrahepatic portal vein, and the main methods can be divided into threshold, enhancement and model methods. Threshold methods use the characteristics of high gray value in portal vein imaging, and perform regional growth within a certain threshold range in the liver to extract portal vein vessels in the liver. This method relies too much on the information of the c...
