Imaging of soil water processes by Magnetic Resonance Imaging (MRI)
BeschreibungMagnetic Resonance Imaging (MRI) is a non-invasive method that can be used to study liquids like water in natural porous media. It is capable to image water content distributions, as well as water flow, diffusion, and solute transport. However, conventional MRI is hampered by inherently short relaxation times in soils. This limitation may be overcome by the used of MRI pulse sequences with ultra-short detection times like SPRITE (single point ramped imaging with T1 enhancement), UTE (ultrashort echo time), or ZTE (zero echo time). Such methods have not been used on soil cores and in combination with tracer tracking methods. In this thesis, existing pulse sequences will be adapted for soil by systematic assessment of pulse sequence parameters to explore the limits in terms of image quality, resolution, and detection. For this, artificial and natural soil cores will be used.

This thesis requires your willingness to come to and work in the Forschungszentrum Jülich for six months.
