Abstract

The invention provides a method and a system for identifying cartilage in a medical image, and solves the technical problem that the existing identification method is low in cartilage identification adaptation degree. The method comprises the following steps: preprocessing a grayscale image to obtain a corresponding gradient image; generating a first edge recognition and a second edge recognitionin the gradient image according to the first edge recognition and the second edge recognition which are respectively formed to form an exact tissue contour, and forming an exact tissue contour in thegradient image according to the first edge recognition and the second edge recognition; and forming a three-dimensional contour of the cartilage tissue according to the change trend between the tissuecontours. Automatic processing and classification are formed by utilizing mutation edges of single quantitative information, so that the tissue edge recognition accuracy is improved. And different contour generation methods are used for verification to avoid over-fitting, so that automatic main body segmentation, accurate contour positioning and automatic three-dimensional modeling of cartilage tissue in a grayscale image are realized, 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 cartilage recognition method and recognition system in medical images. Background technique

[0002] In the prior art, in MRI (Magnetic Resonance Imaging, nuclear magnetic resonance imaging) images, the distinction between articular cartilage and cartilage surrounding tissue is blurred, its contrast is very low, and the thickness of cartilage is relatively thin, and the cartilage is seen from the image in some Parts and connective tissue are in a gray-scale connected state, which causes great difficulties for the automatic segmentation of articular cartilage.

[0003] In recent researches, the research on the algorithm of automatic cartilage segmentation has been going on, and some methods for automatic or semi-automatic cartilage segmentation have also been proposed, most of which are based on statistical shape models or pattern recognition. At present, ther...
