Image segmentation apparatus, medical image device and image segmentation method

摘要

The disclosure provides an image segmentation apparatus, an image segmentation method and a medical image device for segmenting an object having a tree-shaped tubular structure from a volume image consisting of a series of images photographed on the basis of slices. The image segmentation apparatus comprises: a self-adaptive region growing unit configured to perform region growing according to the volume image, based on a seed point and a preset threshold to obtain at least one part of the tree-shaped tubular structure; and a growing control unit configured to change the preset threshold to re-perform the region growing until a given condition is met.

1. An image segmentation apparatus for segmenting an object having a tree-shaped tubular structure from a volume image consisting of a series of images photographed on the basis of slices, comprising:
processing circuitry configured to
perform region growing on the basis of the volume image, based on a seed point and a preset threshold, to obtain at least one part of the tree-shaped tubular structure;determine whether or not the at least one part of the obtained tree-shaped tubular structure is correct;change, when determining that the at least one part of the tree-shaped tubular structure is incorrect and a given condition is not met, the preset threshold to re-perform the region growing until the given condition is met; andperform, when determining that the at least one part of the tree-shaped tubular structure is correct and the given condition is met, centricity-limited region growing on the basis of the volume image, based on the seed point and the preset threshold, to obtain at least one part of the tree-shaped tubular structure.
