NMR imaging of materials is a field of increasing importance. Applications expand from fundamental science like the characterization of fluid transport in porous rock, catalyst pellets, and hemodialyzers into various fields of engineering for process optimization and product and qualitycontrol, for example, of polymer materials, biomaterials, elastomers, and ceramics. While the results of NMR imaging are being appreciated in a growing community, the methods of imaging are far more diverse for materials applications than for medical imaging of humans. This book provides anintroduction to NMR imaging of materials covering solid-state NMR spectroscopy, imaging methods for liquid and solid samples, and unusual NMR in terms of special approaches to spatial resolution like an NMR surface scanner. Special attention is paid to the large variety of ways to generate imagecontrast - the most prominent feature of NMR. The text is strong on methodology, and includes today's important application areas.
