Tomographic techniques are a valuable analytical tool as they deliver 3D spatial information on a given specimen. Both computed tomography with high spatial resolution and quantitative volume image analysis have made enormous progress during the last decade. In particular for materials and natural science applications the combination of high-resolution three-dimensional imaging and the subsequent image analysis exploiting the fully preserved spatial structural information yield new and exciting insights.
In this paper, field-tested and up-to-date methods for tomographic imaging of microstructures, for processing and for quantitatively analysing three-dimensional images are reviewed. By selected applications from materials research, we shall underline the importance of volume image analysis as a crucial step in order to go beyond the images: it allows determination of spatial cross-correlations between different constituents of a specimen, investigation of orientations or derivation of statistically relevant information such as object size distributions. The core part of this work consists, besides the exemple application scenarios, in the processing chain, the tools and methods used.
