The invention discloses a femur and tibia segmentation method and device for a knee joint. The method comprises the following steps: segmenting obtained medical image data to be processed to obtain a three-dimensional medical image of the knee joint, and carrying out corrosion operation on the three-dimensional medical image of the knee joint to obtain a three-dimensional medical image of the knee joint after corrosion treatment in which a femur and a tibia of the knee joint are separated; performing repair operation on pre-segmentation result image data obtained through corrosion processing, filling the corresponding femur or tibia part with sclerotin corroded in the corrosion process to obtain a complete femur and tibia segmentation result, and processing the medical image data by adopting a computer vision technology to obtain a complete femur and tibia segmentation result. Medical image data are processed by adopting a computer vision technology, so the problems of unstable segmentation effect and low speed of a knee joint segmentation method in the prior art are solved, and the technical effects of stable segmentation effect and high segmentation speed are realized.
Description
technical field [0001] The present application relates to the field of computer vision, in particular, to a method and device for segmenting the femur and tibia of the knee joint. Background technique [0002] The femur and tibia are the two most important bone blocks of the knee joint. In knee surgery, the joint prosthesis is mainly placed on the femur and tibia. Accurate and rapid segmentation of the femur and tibia is the premise of precise surgical planning. In the technology, the deep learning method is used to segment the femur and the tibia. However, the deep learning method has a cumbersome training process and a slow running speed, and the effect on some complex cases is unstable. [0003] Therefore, the existing knee joint segmentation methods have the problems of unstable segmentation effect and slow speed. Contents of the invention [0004] The main purpose of the present application is to provide a method and device for segmenting the femur and tibia of the k...
