Various projects to make the raw data more useful for educational purposes are under way. It is necessary to build a three-dimensional virtual model of the body where the organs are labeled, may be removed selectively and viewed from all sides, and ideally are even animated. Two commercial software products accomplish the majority of these goals, the VH Dissector from Touch of Life Technologies and “Voxel-Man 3D-Navigator” from the University of Hamburg NLM itself has started an open source project, the Insight Toolkit, whose aim is to automatically deduce organ boundaries from the data.
