Abstract

Mobile nuclear magnetic resonance deals with unilateral sensors like the NMR-MOUSE® to investigate materials non destructively. The tested samples cover a great range of applications: from elastomers of great importance in materials science to the most complicated biological structures, the essence of the biomedicine. The investigation can be simple NMR relaxometry with a bar or “U” shaped magnet NMR-MOUSE®, profile imaging, and 2D or 3D imaging using an unilateral NMR tomograph. The relaxation times obtained from an exponential fit to echo decay envelopes describe the physical states of elastomers: fatigue, aging, strain, etc. An NMR experiment on a stress-strain device showed a good correlation of a plot of the transverse relaxation times versus strain with the stress-strain diagram. As a new imaging device in biomedicine, the unilateral NMR tomograph was tested. It enables acquisitions of 2D profiles with a planar resolution of 0.8 mm2 and a field of view of 4x4 cm..
