摘　　要：目的研究并实现一个适合于人体腹部解剖教学与学习的图谱系统。方法采用基于Loop细分曲面的拟合方法和基于三维纹理映射的体绘制方法,探讨了截面多边形数目的确定及三维场景的数据组织管理方式。结果针对教学与学习的特点,给出了一个友好的人机交互界面。结论利用该系统,可以有效地学习腹部组织、全方位观察腹部组织的三维几何模型及理解它们之间的空间位置关系,并且可以检验学习掌握程度。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.
