从体积图像中提取平面切片是检查和可视化解剖结构最常用的技术。我们建议将平面截面的概念推广到曲面截面（自由曲面）的提取。与平面切片相比，弯曲的横截面可以容易地遵循管状结构和器官（诸如主动脉或结肠）的轨迹。它们可以从3D体积中提取，显示为3D视图，并且可能被展平。弯曲横截面的展平允许检查解剖结构及其邻域之间的空间复杂关系。它们还允许沿特定方向沿着进行测量。为了便于自由形式表面的交互式规范，用户可以在身体内以真实的时间导航并选择表面控制点将被定位在其上的切片。通过在由解剖器官、平面切片和可能的自由形式表面部分组成的3D视图中将边界曲线显示为圆柱形标记来提供即时反馈。曲面部分的提取是一项附加服务，可作为Java applet（http：//www.example.com）在线使用。visiblehuman.epfl.ch它可以作为一个先进的工具，探索和教学解剖。
The extraction of planar sections from volume images is the most commonly used technique for inspecting and visualizing anatomic structures. We propose to generalize the concept of planar section to the extraction of curved cross-sections (free form surfaces). Compared with planar slices, curved cross-sections may easily follow the trajectory of tubular structures and organs such as the aorta or the colon. They may be extracted from a 3D volume, displayed as a 3D view and possibly flattened. Flattening of curved cross-sections allows to inspect spatially complex relationship between anatomic structures and their neighborhood. They also allow to carry out measurements along a specific orientation. For the purpose of facilitating the interactive specification of free form surfaces, users may navigate in real time within the body and select the slices on which the surface control points will be positioned. Immediate feedback is provided by displaying boundary curves as cylindrical markers within a 3D view composed of anatomic organs, planar slices and possibly free form surface sections. Extraction of curved surface sections is an additional service that is available online as a Java applet (http://visiblehuman.epfl.ch). It may be used as an advanced tool for exploring and teaching anatomy.
