Fuzzy expert system for foot CT image segmentation
This paper proposes a fuzzy expert system scheme for foot CT image segmentation. Our method aims at decomposing a fractured foot bone into each of fragments and normal bones, as a framework of developing a computer-aided orthopedic surgery planning system. It employs fuzzy knowledge representation to express orthopedic surgeon's knowledge: knowledge of distance to extract fragments and knowledge of intensity distribution to decompose adjoining normal bones on the articular cartilage. The two types of knowledge are compiled to a total degree, which is evaluated in the segmentation procedure. Qualitative evaluation of an orthopedic surgeon shows that our method could correctly segment the bones and fragments.
