Titel: Imaging and image-based modelling of biological and material systems

Abstract: Synchrotron radiation-based computed tomography (SRμCT) is a powerful tool for high-resolution imaging of materials. Whilst it traditionally depends on the X-ray attenuation by material components with high Z-numbers, it can be enhanced to enable imaging of biological soft tissues and other low-attenuation materials through propagation-based phase contrast. Due to the available high photon flux it is also possible to perform in situ testing, e.g. of material corrosion or mechanical loading experiments. In combination with image-based mathematical modelling, SRμCT enables the correlation between morphological and/or structural material measures and their function. In this presentation, showcases will be presented where SRμCT and image-based modelling have successfully been used to this end. These showcases include the assessment of osseointegration and in vitro degradation of biodegradable implants, the computational analysis of oxygenation in mouse muscle and the corrosion of steel embedded in concrete in aqueous solutions.
