Abstract

The invention provides a method and system for separating ankle ligaments in a medical image, solving the technical problem that the separation precision cannot be further improved through an existingankle ligament separation method. The method comprises the following steps: preprocessing a grayscale image to obtain a corresponding gradient image; forming an exact tissue contour in the gradient image according to sequential first edge recognition and second edge recognition; and forming a three-dimensional contour of the ligament tissue according to the change trend between the tissue contours. Automatic processing and classification are formed by utilizing mutation edges of single quantitative information, so that the tissue edge recognition accuracy is improved. Different contour generation methods are used for verification to avoid over-fitting, so that ligament tissue can realize main body automatic segmentation, contour accurate positioning and automatic three-dimensional modeling in a grayscale image, and the recognition efficiency of professional human recognition resources is effectively improved.

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...
