Ankle ligament separation method and separation system in medical imaging

Abstract

The present invention provides a method and system for separating ankle ligaments in medical imaging, solving the technical problem that the existing means of separating ankle ligaments cannot further improve the separation accuracy. The method includes: preprocessing the grayscale image to obtain a corresponding gradient image; forming an exact tissue contour according to the sequential first edge recognition and the second edge recognition within the gradient image; and based on the changes between the tissue contours The tendency forms the three-dimensional outline of the ligament tissue. Utilizing single quantitative information to form automated processing and classification of mutation edges, the accuracy of tissue edge identification is improved. Different contour generation methods are used for verification to avoid over-fitting, so that ligament tissue can achieve automatic subject segmentation, accurate contour positioning and automatic three-dimensional modeling in grayscale images, effectively improving the identification efficiency of professional human identification resources.

Description

technical field [0001] The invention relates to the technical field of medical image recognition, in particular to a method and system for separating ankle ligaments in medical images. Background technique [0002] The structure of the ankle is complex, including bones, tendons, blood vessels, and nerves. There are many small bones, and the distribution of interskeletal ligaments is dense. The contours of tissues other than bones are often unclear due to the gray-scale resolution of MRI (Magnetic Resonance Imaging, MRI), and the combination of edge gray-scale areas between tissues makes it difficult to segment ligament images [0003] In the prior art, it is necessary to manually perform selective editing, defect compensation processing, artifacts and redundant data separation on various tissue patterns, and then use a region growing method to generate segmentation results to establish a complete digital model. This will consume a lot of time for operators, and professional...
