    <title language="eng">Note: X-ray radiography for measuring chemical diffusion in metallic melts</title>
    <abstract language="eng">A x-ray radioscopy technique for measuring in situ chemical diffusion coefficients in metallic melts
is presented. The long-capillary diffusion measurement method is combined with imaging
techniques using microfocus tubes and flat panel detectors in order to visualize and quantitatively
analyze diffusive mixing of two melts of different chemical composition. The interdiffusion
coefficient as function of temperature and time is obtained by applying Ficks diffusion laws.
Tracking the time dependence of the mean square penetration depth of the mixing process allows to
detect changes in the mass transport caused by convective flow. The possibility to sort out
convective mass transport contributions from analysis enhances significantly the accuracy compared
to the conventional long-capillary diffusion measurement method with postmortem analysis. The
performance of this novel diffusion measurement method with x-ray radiography technique is
demonstrated by a diffusion experiment in an Al-Ni melt.</abstract>

    <title language="eng">Reconstruction of limited view tomography data by DIRECTT</title>
    <abstract language="eng">Incomplete tomographic data sets such as limited view (missing wedge) data represent a well-known challenge for reconstruction algorithms, since they unavoidably lead to substantial image artefacts. Such data sets may occur in industrial computed tomography of limited access (e.g. extended components, fixed objects), directional opacity, limited sample life time or laminographic set-up. We present strategies to effectively suppress the typical elongation artefacts (e.g. lemon-like deformed pores) by our iterative algorithm DIRECTT which offers the opportunity to vary the versatile reconstruction parameters within each cycle. Those strategies are applied to experimental data obtained from metallic foams as well as model simulations. Comparison is drawn to state-ofthe-art techniques (filtered backprojection and algebraic techniques). Further reference is made to reconstructions of complete data sets serving as gold standards. For quantitative assessment of the reconstruction quality adapted techniques based on spatial statistics are introduced.</abstract>
