Abstract

The embodiment of the invention discloses an image segmentation method and device, equipment and a storage medium. The method comprises the steps of obtaining image data of a target object, and determining a to-be-segmented image according to the image data; Segmenting the to-be-segmented image based on a preset low-threshold region growing algorithm to obtain an initial segmented image with a tubular structure; performing skeletonization processing on the initial segmented image to obtain an image tree with a tubular structure; and cutting the image tree based on a preset high-threshold probability cutting algorithm, and determining a segmented image of the tubular structure according to the cut image tree. According to the technical scheme provided by the embodiment of the invention, theproblem of incomplete segmentation or segmentation leakage in the existing scheme is solved, the tubular structures such as trachea, blood vessels and coronary vessels in the medical image can be accurately segmented, and a basis is provided for medical diagnosis.

Description

technical field [0001] Embodiments of the present invention relate to medical image processing technology, and in particular to an image segmentation method, device, equipment and storage medium. Background technique [0002] Cardiovascular disease is a disease with high morbidity and mortality. Cardiac coronary artery segmentation based on computer X-ray tomography (Computed Tomography, CT) technology can extract the left and right coronary tree outlines of coronary arteries and the trunk and trunk of coronary arteries. Twigs can make it easier for doctors to observe conditions such as stenosis, calcification, and plaque, thus providing a basis for doctors to prevent and diagnose cardiovascular diseases in the early stage. [0003] The segmentation of existing tubular structures such as blood vessels, trachea, and coronary arteries is mostly based on region growing technology or centerline tracking technology. However, the segmentation technology based on region growth is ...
