Magnetic Resonance ofPorous Media andBrain
Yiqiao Song
School of Engineering and Applied Science, Harvard andMartinos Center for Biomedical Imaging, Massachusetts General HospitalPorous material is ubiquitous in nature and human life: rocks, soil, wood, food, and biological tissues are good examples. They are intrinsically multi-phasic, and their microstructure is critical for their functions. In recent years, NMR/MRI has become an important technique for characterization of a variety of porous media for petroleum/groundwater exploration, material sciences, and medical imaging. This talk will discuss measurement techniques of the material porosity, and the heterogeneity. In particular, we will highlight the correlational method that is crucial for complex natural materials and biological tissues. Examples of NMR/MRI methods will be discussed including multi-echo techniques, 2d methods with applications in polymer degradation, molecular composition, porosity in sedimentary rocks, food products and biological tissues. If time permits, we will also highlight the novel hardware innovation such as non-resonant MR electronics and miniaturization using ASIC.
