Analysis and 3D reconstruction of bone trabeculae by computer aided technique

摘要

An attempt has been made to develop an image processing system for the analysis of the trabeculae. The trabecular images from a series of X-ray pictures of sliced bone are analyzed from the viewpoint of the thickness, density, and direction as the projected state in a plane. Next, the conditions for connecting three-dimensionally the data obtained from several slices are considered in order to reconstruct the three-dimensional structure of the trabecular system. The object of the analysis is trabeculae of the pelvis, which have a three-dimensionally complicated structure.
