The Voxel-Man 3D-Navigators are a family of interactive anatomical atlases for Windows PCs. The following 3D-Navigators were published:
Voxel-Man 3D-Navigator: Upper Limb (2008) — interactive anatomical atlas of the hand, arm and shoulder
Voxel-Man 3D-Navigator: Inner Organs (2000/2003) — interactive anatomical atlas of the inner organs
Voxel-Man 3D-Navigator: Brain and Skull (1998/2001/2009) — interactive anatomical atlas of the brain and skull
Until well into the 2000s, interactive visualization of medical volume models was only possible on high end workstations. This applied in particular to high resolution models, such as those derived from the Visible Human.
To overcome these limitations, a new paradigm based on pre-calculated interactive scenes of the model was developed. As the base technology, the QuickTime VR format was chosen which allows for an interactive exploration with two degrees of freedom. As a decisive innovation, it was extended by a pixelwise link to an anatomical knowledge base that can be queried in the image context.
For authoring of a scene, the two degrees of freedom can be freely chosen, for example
- rotation of the model around 2 axes
- rotation around 1 axis, combined with a stepwise removal of anatomical layers
- translations of 2 orthogonal dissecting planes
A user can explore a scene largely with the functionality of a full visualization system, but in real time and without the complexites on any standard PC.
