This virtual anatomy teaching system captures the three key factors. The virtual interaction mode, which is similar to actual anatomical specimen observation and dissection, can enhance the transmissibility of anatomical knowledge. The perception of knowledge is realized by the Yi Chuang Digital Human Anatomy Teaching System that we have created. Various kinds of anatomical knowledge and 3D digital anatomical models are organically combined to construct virtual anatomy teaching system by means of virtual reality equipment and technology.
![]() ![]() Some structures lacking original data sources need to be hand drawn according to their morphological features and spatial adjacency, such as white matter fiber bundles of the brain, blood vessels of the fingers, and diaphragms. Most of the virtual simulation models used in the virtual anatomy teaching system come directly from these digital anatomical specimens.In order to express the authenticity and comprehensibility of specimens more effectively, some 3D reconstructed models usually need to be patched and beautified, such as 3D models of the brain and sulcus. Complete and realistic 3D models, that is, digital anatomical specimens, can be obtained by image segmentation and 3D reconstruction of these images. These images have ultra-high spatial resolution, and the structures are recognizable. Morphological modelingThe CVH images are optical images obtained by milling and cutting human cadaver specimens using frozen tomographic milling technology. The simulation models of the virtual anatomy teaching system constructed here contain 3D digital anatomical models of human morphological structure and anatomical knowledge ontology. Contoh judul skripsi manajemen pemasaranLearners can thereby obtain visual and intuitive perceptions from the 3D digital anatomical models. The selected texture map is based on the colors and textures of the real anatomical specimens and combines the functional expressions of the human body structure. Finally, a 3D model library of human morphological structures required by the virtual simulation teaching system is formed (Fig. In addition, morphological information of each nerve nucleus in the brain stem needs to be obtained by stained tissue sections, and the dynamic 3D model of the heart comes from the sequence data of the multi-period in the cardiac physiological cycle.Under the principle of not affecting the morphological expression of the structure, the number of patches of the constructed 3D models is deleted as appropriate, and pseudo-color and texture mapping processing is performed. It is necessary to use the diffusion tensor imaging data of white matter to construct each white matter fiber bundle required for the virtual simulation teaching system. For example, the white matter fiber bundle of the brain is white on the sectional specimen, so it is impossible to distinguish each white matter fiber bundle. Bach violin sheet musicThe instantiation of the anatomical ontology can realize the organic relationship between the spatial information and the anatomical knowledge of the morphological structure, which is conducive to the perception and propagation of anatomical knowledge.Virtual anatomical models are the basis of the virtual anatomy teaching system. The models instantiated inherit all the relationships and attributes in the anatomy ontology and contain the unique information and 3D visualization model (Fig. It is then necessary to construct the anatomical knowledge ontology, Bo = , where Bo is the anatomical ontology, Bi is the basic information of the individual, Bm is the 3D model of the individual, Ps is the individual tomographic image, and RL is the relationship between spatial position and terminology.
