Method for segmenting and marking multi-branch tubular structure in three-dimensional image

The invention provides a method for segmenting and marking a multi-branch tubular structure in a three-dimensional image, and belongs to the field of medical image processing. According to the method,a multi-branch tubular structure is regarded as a set of a plurality of single-branch tubular structures, and for the single-branch tubular structures, a center line is obtained through key point detection and neural network fine adjustment methods; then a cross section image of the tubular structure is acquired along the center line based on the center line, and finally a segmentation result ofthe tubular structure is acquired by using a segmentation network. The specific multi-branch tubular structure existing in the image can be segmented and automatically marked, and especially for someimages with lesions, such as aortic dissection, aortic aneurysm and coronary artery stenosis images, a good segmentation result is achieved. 本发明提出一种三维图像中多分支管状结构分割与标记方法，属于医学图像处理领域。该方法把多分支管状结构看作多个单分支管状结构的集合，对于单分支管状结构，通过关键点检测和神经网络
