Abstract

The invention provides a blood vessel segmentation method and device and electronic equipment, and the method comprises the steps of obtaining a target region which comprises a to-be-segmented region;determining blood vessel candidate pixel points based on a preset blood vessel model and a fuzzy clustering algorithm; extracting a first blood vessel according to the blood vessel candidate pixel points; extracting second blood vessels based on the first blood vessels, and the density of the first blood vessels is larger than that of the second blood vessels; and combining the first blood vesseland the second blood vessel to obtain a blood vessel segmentation result. According to the invention, the influence of other tissues with similar blood vessel characteristics on blood vessel segmentation can be effectively reduced, and the influence of blood vessel characteristics on blood vessel segmentation can be effectively reduced. The invention can improve precision of blood vessel segmentation.

Description

technical field [0001] The present application relates to the technical field of medical images, in particular to a blood vessel segmentation method, device and electronic equipment. Background technique [0002] Due to the complex structure of human blood vessels and the aging of the global population, there are many types of vascular diseases, and the incidence of vascular diseases is also increasing year by year. As a simple, rapid, non-invasive and safe method, multi-slice spiral CT angiography (CTA) is widely used in the diagnosis of vascular diseases. Separating and extracting the vascular structure from the CTA chest and abdomen data can assist doctors in observing the vascular structure, diagnosing vascular diseases and setting surgical plans. [0003] For vessels with complex structures, due to their complex structure, it brings great challenges to accurate segmentation, such as thoracoabdominal vessels, which have very complex structures, many vessels, and the sca...
