Title: Methods for time-resolved X-ray tomographic microscopy and multi-scale acquisition.

IX-ray tomographic microscopy may be performed with conventional X-ray sources or using synchrotron radiation. The specificities of synchrotron X-ray imaging is the high speed. Individual angular projections are acquired on a sub-ms time-frame and the entire tomographic dataset in a fraction of a second. This enables time resolved studies of dynamic processes at the micrometre spatial and sub-second temporal resolution. Despite this fast acquisition in dynamic tomography, the sample is often evolving quicker, giving rise to motion artefact in the reconstructed volume. I will present state-of-the-art acquisition and reconstruction methods which can reduce those artefacts.
A second, recently often demanded feature is multi-resolution acquisition. On selected examples I will explain the challenges and achievements made in this direction.
