In current practice, anatomical atlases are based on a collection of planar images presented in a book or, recently, stored on digital media. We present a new method for generating interactive true three-dimensional (3D) anatomical atlases based on a volume model derived from MRI and CT. The model has a two layer structure. The lower level is a volume model with a set of semantic attributes connected to each voxel. The semantic attributes are assigned by an anatomist using a volume editor. The upper level is a set of relations between these attributes. Interactive visualization tools such as multiple surface display, transparent rendering, and cutting are provided. It is shown that the combination of this data structure with advanced volume visualization tools provides the "look and feel" of real dissection. First tests show that the atlas system cannot only be used successfully for anatomy teaching, but also as a reference for radiologists or surgeons. As a replacement of classical atlases, however, the spatial resolution has still to be improved.
在当前的实践中，解剖图谱基于书中呈现的一系列平面图像，或者最近存储在数字媒体上的图像。我们提出了一种基于从MRI和CT得出的体模型生成交互式真实三维（3D）解剖图谱的新方法。该模型具有两层结构。较低层是一个体模型，其中一组语义属性连接到每个体素。语义属性由解剖学家使用体编辑器进行分配。较高层是这些属性之间的一组关系。提供了诸如多表面显示、透明渲染和切割等交互式可视化工具。结果表明，这种数据结构与先进的体可视化工具相结合，提供了真实解剖的“视觉和感觉”。初步测试表明，该图谱系统不仅可以成功用于解剖学教学，还可以作为放射科医生或外科医生的参考。然而，作为传统图谱的替代品，其空间分辨率仍有待提高。
