In this paper a method for creating geometrical models of tree-like anatomical structures is described. This method is basically interactive and thus it takes advantage of the user's expertise to define highly-structured models even when using nonhomogeneous data sets. First, tubular cavities are reconstructed sequentially; then, junctions between these cavities are provided in such a way that resulting models are continuously shaped (we characterize this property by the G1-continuity (i.e., a tangent plane can be defined at any point on the surface).
本文描述了一种创建树状解剖结构几何模型的方法。该方法基本上是交互式的，因此即使使用非均匀数据集，也能利用用户的专业知识来定义高度结构化的模型。首先，依次重建管状腔；然后，以这样一种方式提供这些腔之间的连接，使得生成的模型具有连续的形状（我们用G1连续性来描述这一特性，即在曲面上的任何点都可以定义一个切平面）。
