Analysis and 3-Dimensional Reconstruction of Bone Trabeculae by Computer Aided Technique
Inside the bone, the trabecular system of the spongy bone is observed, which has a complicated mesh-like structure. The configuration and structure of trabeculae are strongly related to the loads acting on the bone. Therefore, the trabecular system gives us useful information about the mechanical environment of the bone. In this study, the trabecular images from X-ray pictures of the bone sliced from the pelvis are analyzed from the viewpoint of the thickness, the density and the direction through an image processing. The processed trabecular lines are reconstructed three-dimensionally by using some rules in order to know three-dimensional flow of the force.
