定义了任意对象的欧拉数和连通性，说明了为什么n维对象的连通性无法在(n-1)维截面中估计。松质骨中说明了欧拉事件 3D 计数的解剖原理。概述了对人工边缘处的事件进行无偏计数的正确处理。提供了用于预测估计精度的列线图。
The Euler number and the connectivity of an arbitrary object is defined, and it is illustrated why the connectivity of an n-dimensional object cannot be estimated in an ( n - 1 ) dimensional section. The disector-principle for 3-D counting of the Euler-events is illustrated in cancellous bone. The correct handling for unbiased counting of events at artificial edges is outlined. A nomogram for predicting the precision of an estimate is provided.
