Subproject S – Tomography – combines service and scientific aspects in four working points (WP). In WP 1 "Conception of computer tomographic recording procedures", the focus is on data acquisition including task-specific recording schemes, whereby several tomographs are used at different locations. In the second work item, "Software basis and data storage", various evaluation programmes are analysed and made available, and concepts for long-term data storage are created. To minimise systematic residual errors of the tomograph, algorithms and concepts are developed in the third work item "System calibration". "Geometric registration", which is the subject of WP 4, comes into play in the analysis of changes in time series recordings or in the integration of recordings from devices with different functional principles. This includes the detection of rigid body movements.
