Problems solved by technology
[0003] The traditional key point detection of human bones is automatic or semi-automatic, and needs to rely on the doctor's own prior knowledge to draw manually. This method of selecting key nodes is inefficient and will bring differences between observers and observers themselves.

The method and device for detecting bone key points in joint replacement surgery provided by the embodiments of the present invention, the method includes: acquiring a bone CT image of the target part on the patient's body, obtaining multiple perspective segmentation images according to the bone CT image, and using the pre-stored Acquiring standard reference images corresponding to each of the plurality of perspective segmentation images in the skeleton atlas library, and marking key points to be determined in each perspective segmentation image according to each perspective segmentation image and corresponding multiple standard reference images, And obtain the position information of the key points to be determined, realize accurate and efficient automatic detection of bone key points in medical images such as CT, thereby assisting surgical planning and navigation, and improving surgical quality.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and in particular to a method and device for detecting bone key points in joint replacement surgery. Background technique [0002] Joint replacement surgery is currently an effective means of treating bone and joint diseases. It can effectively eradicate joint pain, restore joint function and improve the quality of life of patients. In the process of surgical planning, it is necessary to determine the key points of bones based on CT and other medical images, and further generate anatomical axes and lines of force. [0003] The traditional human skeleton key point detection is automatic or semi-automatic, and needs to rely on the doctor's own prior knowledge to draw manually. This method of selecting key points is inefficient and will bring differences between observers and observers themselves. Contents of the invention [0004] Aiming at the problems e...
