Study on the key technology for designing three-dimensional human anatomy atlas

Objective To develop a three-dimensional(3D) abdominal atlas system for teaching and learning abdominal anatomy.Methods The Loop subdivision surface was applied to fit 3D abdominal data to achieve a high quality model.Texture-based volume rendering technique was used to visualize volume data.The determinations of section number of slicing proxy polygon,the organization and management of data in 3D scene graph were studied.Results A user-friendly human-computer interface of abdominal atlas system was developed,which could meet certain needs of learning and teaching.Conclusion It is demonstrated that the user could learn abdominal tissues and observe 3D model of abdominal organs from all angles,and understand the 3D relationships of different organs effectively.It could also be used to detect the familiarity with the abdominal anatomy.
