Method for making three-dimensional visualization model of internal structure of bone
The invention is a method for making a three-dimensional visualization model of the internal structure of bone. In the method, a dry bone specimen is embedded and fixed by transparent polymethyl methacrylate (PMMA) to form a model specimen, and then the cross-section of the specimen is ground layer by layer, two-dimensional grayscale images and true color images are scanned and recorded layer by layer, and then three-dimensional medical reconstruction software is used to obtain high-precision three-dimensional visual model of a proximal bone structure. The invention can be applied to three-dimensional reconstruction of bones of human bodies and animals, thereby obtaining the high-precision three-dimensional visual model which can objectively, truly and completely reflect the proximal bone structure. The method can carry out certain evaluation on the structural form of bone trabecula as well as the connectivity of three-dimensional bone trabecular, and can determine the structural parameters of bone trabecular, thus providing scientific basis for medical research and clinical care.
