Seeing and understanding 3-d medical images through 2-d renditions

The efficiency of data analysis of 3-d measurement data such as medical images can be enhanced if the expert user is enabled to incorporate his knowledge into the analysis process in an interactive fashion. Potential misinterpretation may arise from the necessary information reduction when presenting the 3-d data by a 2-d rendition. We present concepts of data visualisation during analysis, which is intended to avoid such problems during data analysis. The emphasis is on providing a visualisation, which transfers information such that the user perceives not only the data but also the state of interpretation. Simple metaphors are presented which support the development of methods under these concepts. Hybrid and focal volume rendering illustrate as examples a realisation of aspects of the concept for analysing high-resolution CT data.
