Abstract

The invention discloses a method and a system for assisting in recognizing a force line by using a neural network, which can be used for detecting the force line before and after an operation, assisting the operation and knowing the postoperative recovery condition. The method comprises the steps that CT file sequence rows are combined into a complete three-dimensional image, then slicing is carried out on a coronal plane to obtain a first image, the first image is input into a first multi-classification segmentation neural network based on unet and using a softmax activation function to carry out different classification on a femoral and a tibia, and therefore, a femoral model and a tibia model are segmented at one time; and a femoral head center point on the femoral model is searched by using a second segmentation neural network to determine the force line, wherein other key physiological points, namely a femoral knee joint center point, a tibia knee joint center point and a tibia ankle joint center point, are calculated based on the point cloud. The first image is subjected to a bilinear quantization process such that downward quantization can also be performed while upward interpolation is performed by a bilinear interpolation.

Description

technical field [0001] The present invention relates to the field of medical technology, that is, the field of computer-aided planning technology for joint replacement and the technical field of medical image data processing. More specifically, it involves a method based on image reconstruction, deep learning, and numerical algorithms to calibrate the line of force, especially redesigning a different deep learning marking scheme based on the coronal plane. Background technique [0002] With the rapid development of modern society, all walks of life have begun to have an inseparable connection with the IT industry, and the same is true for the medical industry. Determining the position of the force line is very important in assisted knee arthroplasty by surgical robot, which can determine the success of the operation and the postoperative recovery status of the patient. If the calibration of the force line is not accurate, it may cause the patient to re-introduce the lesion ...
