Gross anatomical structures can be labeled by medical students. At the fine detail level, a skilled and experienced anatomist must be involved. Putting into their hands a straightforward, interactive system can greatly speed up the task involved. For example, they can easily flip between images on either side, view the relationship of the voxel in each of the three orthogonal views, and link to the developing text database and so on to follow a small structure down to its final voxel. The simple speed and smoothness of the browsing assist in the detection of anomalies during the segmentation.

      A fuller implementation would link the PC to the more numerically powerful workstation where the extensive number crunching of first order segmentation is done semi-automatically but now interactively steered and quality controlled by an operator supported by the image browser tools.
