Abstract

The invention relates to a blood vessel segmentation method and device, computer equipment and a storage medium. The method comprises the following steps: selecting a to-be-grown seed point of a to-be-grown blood vessel according to a blood vessel image; based on the blood vessel image, the to-be-grown seed point, a preset threshold value and a coronary artery tracking model, determining a mask set, and determining a tracking mask according to the mask set; if the tracking mask does not meet a first preset condition, reducing the preset threshold, updating the seed point to be grown based on the tracking mask, and repeating the process of determining the tracking mask until the determined tracking mask meets the first preset condition; and determining a blood vessel segmentation image based on each determined mask set and the blood vessel image. According to the invention, under-segmentation or over-segmentation caused by using a unified threshold value can be avoided, and the accuracy of blood vessel segmentation is improved.

Description

technical field [0001] The present application relates to the technical field of medical image processing, in particular to a blood vessel segmentation method, device, computer equipment and storage medium. Background technique [0002] The segmentation and extraction of blood vessels is an important prerequisite for the quantitative description of diseases and three-dimensional reconstruction of blood vessels, and it is also an important means to assist doctors in clinical diagnosis and treatment. Region growing methods are more common in vessel segmentation. [0003] The region growing method first sets a seed point, continuously traverses the neighborhood of the seed point, puts the points similar to the seed point into the same set, and then finds the similar points in the neighborhood of the midpoint of the set, and continuously expands the area until it is completed segmentation. The currently commonly used image segmentation methods based on seed points are generall...
