Abstract

The embodiment of the invention discloses a knee joint cartilage injury detection method and system, and the method comprises the steps: obtaining knee joint MRI image information, and carrying out the preprocessing of the image information; extracting a cartilage injury area layer by layer according to the preprocessed image information to obtain a knee joint cartilage three-dimensional volume area; extracting a cartilage injury region of interest layer by layer to obtain a cartilage injury three-dimensional region; extracting features of the three-dimensional region of interest, training a classifier network by adopting a neural network method, and determining an optimal model; inputting the knee joint MRI image information into the optimal model, carrying out the cartilage injury detection, and determining the cartilage injury degree. The method is good in robustness, rapid, convenient and suitable for assisting doctors in diagnosis.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical detection, and in particular to a method and system for detecting knee articular cartilage damage. Background technique [0002] Osteoarthritis (OA) is a common chronic, progressive and highly disabling joint degenerative disease. The diagnosis of knee cartilage injury provides an important reference for clinical practice. MRI, as a multi-parameter imaging examination method, can detect changes in the matrix composition of the knee articular cartilage before pathological and morphological changes, so as to make an early diagnosis of the degree of cartilage damage in the knee joint. With the continuous development and research of computer software, and the use of various high-signal-to-noise ratio and high-resolution magnetic resonance sequences, more and more image algorithms are applied to the automatic detection of knee cartilage, and an MRI-based A non-invasive, ra...
