Digital human anatomy system：
1.The system has five parts: systematic anatomy, regional anatomy, sectional anatomy, anatomy micro course and independent learning, which can meet the systematic anatomy teaching, regional anatomy teaching, sectional anatomy teaching.
2. The 3D human body must be reconstructed with the real data of continuous tomography of human body without organic disease and no missing. The data shall be the tomographic data without missing segmental data. The structures such as teeth, male testis, appendix and fat layer must be intact.
38. Digital human cross-sectional distance: head and neck are ≤0.5mm, of which the base of the skull is ≤0.1mm, other parts are ≤1.0mm, and the total tomographic data is >2100. Real human body tomographic images with cross-sectional, coronal, and sagittal planes, which can be zoomed in and out at will, with a resolution of ≤0.18mm×0.18mm/pixel.
3. The human body is accurately reconstructed using real medical data, includes at least 6000 non separable anatomical structures. Each anatomical structure must be annotated with description to meet the needs of teaching.
4. The system has five modules: systematic anatomy, regional anatomy, sectional anatomy, anatomy micro course and autonomous learning.
5. In this system, human structures can display in 3D, which can be enlarged, reduced and rotated at any angle. 
6. In the system, the anatomical structure in each fault of the transverse, sagittal and coronal sections shall be circled and marked to facilitate viewing the position and range of each anatomical structure in the fault, and must be associated with the 3D human body. Click any structure position of the 3D or fault, and other areas will respond synchronously.
7. The preset position function is set in the system to facilitate the teacher to establish magnetic stickers according to the teaching content, and quickly find the set 3D human body structure during the teaching. Each preset position magnetic sticker
