Embodiment Construction
[0035] The embodiments and effects of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] refer to figure 1 , the implementation steps of this embodiment include the following:
[0037] Step 1. Obtain a dataset of knee joint MRI images.
[0038] 1.1) The data of 2,000 cases of knee joint MRI imaging examinations were obtained from the imaging department of the tertiary first-class hospital, and the data that did not meet the requirements of clinical diagnosis of knee meniscus injury such as the history of surgery and the history of internal fixation of the joint were excluded;
[0039] 1.2) Utilize the sagittal and coronal slice images from the data selected in 1.1) to form a data set for positioning the meniscus region, and use 60% of it as a training set and 40% as a test set;
[0040] 1.3) For all the MRI images of the knee joint in the meniscus area positioning dataset obtained in 1.2), mark the labels of the meni...
