Conclusions

     The goal of this environment is to move the expert medical knowledge of the end user into the visualization and segmentation process. This is accomplished by merging the activities of visualization and segmentation into a intuitive action completely under the user's control. In this way, segmentation choices are made in parallel with the visualization of the data set allowing the user to control the process based upon context knowledge and what they expect to see. Furthermore, the process allows the user to interactively concentrate computational resources on imaging those features of greatest value.

     It also presents a possibility for bridging the gap between the level of structure describable in the language of image processing and the higher level features of interest to users. The structural and contextual knowledge contained in knowledge bases of the kind described in [1] could be used to interactively support the user during visualization and segmentation.
