Abstract
A method and system for extracting vasculature. The method may include obtaining an image including a part representing a vessel, and obtaining a first image by extracting bone tissue in the image. The method may also include obtaining a second image by performing a region growing operation on the image. The method may further include generating a subtraction image based on the first image and the second image. The subtraction image may include at least a portion of the part representing the vessel in the image. The method may also include obtaining at least one vessel seed group based on a first condition and the subtraction image, and determining at least one vessel threshold based on at least one boundary distance field of the subtraction image. The method may further include obtaining a target vessel image by performing, based on the vessel seed group and the at least one vessel threshold, a region growing operation on the image.
