目的 数字三维解剖模型对于解剖学教育和临床医疗研究起到了积极的推动作用。现有的中国人数字三维模型多是基于一个标准的人类个体，不包含人与人之间的解剖形态变化差异，不利于使用者了解器官形态在不同人之间的变化。我们提出了1种基于万维网（Web）端的三维可视化人体躯干解剖形变模型，在浏览器网页中展示中国人群的器官解剖形态变化规律。 方法 通过统计形状模型技术，从138例健康中国人计算机断层扫描（CT）影像中学习到器官形态个体差异，并通过Web端浏览器交互展示这种变形差异。 结果 本系统实现了基于网络的操作模式，通过用户交互式操作调整模型参数来展示人体解剖学信息和个体间变化。结论 本研究中的Web端三维可视化解剖形变模型实现了跨平台、跨操作系统，达到了实时操作，为解剖教学与医疗应用提供了个体差异信息。

Objective Digital three-dimensional (3D) anatomical model have promoted anatomy education and clinical research and treatment. However, most existing digital 3D models of Chinese human are based on standard human subjects which do not include the anatomical variations between different individuals. This limitation hampers the users’ understanding of inter-subject organ morphology variations. Therefore, we constructed a web-based 3D visualization system of human trunk anatomical deformation model to demonstrate these variations. Methods We learned the individual differences of organ morphology from 138 healthy Chinese CT images using the statistical shape model technique, and interactively demonstrated the deformation of anatomical variances through web browser. Results The proposed system realized cross-platform network-based visualization and allowed the adjustment of anatomical deformation through the user’s interactive operation. Conclusion Our web-based system provides novel inter-subject variation information for anatomy education and medical applications.
