Bone destruction degree feature extraction system

Abstract

The invention discloses a bone destruction degree feature extraction system, which includes a joint statistical morphological model building module, a pathological morphological model matching module, and an abnormality detection and analysis module, wherein the joint statistical morphological model building module is used to construct a joint statistical morphological model, Extract specific morphological statistical features for each piece of bone; the pathological morphological model matching module is used to find a model instance closest to the pathological sample in the joint statistical morphological model, and limit the model instance to three times the standard of the average morphological model Within the difference, the influence of normal anatomical variation is eliminated, and the pathological changes are highlighted; the target information used by the abnormality detection and analysis module is the degree of osteogenesis and osteoclastion of each bone, by calculating the normal The negative distance realizes quantitative evaluation of osteoclast and osteoblast. In this way, the quantitative calculation of bone destruction evaluation indicators can be realized, and reference information can be provided for the evaluation of the position and degree of bone destruction in patients.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a bone destruction degree feature extraction system. Background technique [0002] Rheumatoid arthritis is an autoimmune disease with a high incidence in middle-aged and elderly people, but it can also be seen in other age groups. Rheumatoid arthritis is a chronic disease, and long-term rheumatoid arthritis can lead to physical disability. Chronic inflammation of the synovial bursa occurs in some patients with rheumatoid arthritis, leading to destruction of articular cartilage and bone. Bone destruction can be regarded as an imbalance between the two processes of osteogenesis and osteoclasticity. In normal human body, the process of osteogenesis and osteoclasticity is finely regulated to ensure bone stability. In patients with rheumatoid arthritis, the strength of bone fragmentation is greater than that of bone formation, resulting in changes in joint structure and ultimately ...

Problems solved by technology

[0003] The evaluation of the degree of bone destruction in patients often relies on medical staff to observe various images based on X-rays to judge the degree of bone destruction in patients. However, manual evaluation requires evaluators to have high professionalism, and manual evaluation is prone to subjective impressions. influences
