Miniaturization of Magnetic Resonance



Nuclear magnetic resonance (NMR) is widely used in chemistry, biology and industries to character molecules and their nanoscale structure. Its imaging modality, magnetic resonance imaging (MRI) is the dominating method used in medicine to provide a structural and functional diagnosis of diseases and treatment monitoring. It is also used extensively to characterize subsurface formations to understand fluid transport in porous rocks and soils with applications in petroleum exploration, groundwater and geothermal reservoir characterization. However, the bulky conventional electronics used in conventional systems result in the high cost of the NMR instrument and limit its applications. This talk will discuss our efforts to miniaturize NMR by using permanent magnets and ASIC (application-specific integrated circuit) chips to encapsulate all essential functions of NMR spectrometers. We will first introduce the relevant spin physics to perform NMR measurements, outline the requirement of the NMR system, and discuss our ASIC designs. Experimental data will be presented to showcase our miniaturized NMR system to characterize a wide range of materials. We will highlight in particular the ability of our system to perform complex NMR experiments such as two dimensional experiments that are crucial for complex natural materials and biological tissues.


SONG Yiqiao received a B.S. degree from Peking University in 1985 and a Ph.D. degree in physics from Northwestern University in 1991. Currently, he is a Research Scientist at Harvard University and research staff in Massachusetts General Hospital. Dr. Song is a Fellow of the American Physical Society and International Society of Magnetic Resonance, Associate Editor of Frontiers of Physics, the Journal of Magnetic Resonance and Petroleum Sciences, member of the editorial boards at Magnetic Resonance Letters and the Chinese Journal of Magnetic Resonance. He is also the chair of the Magnetic Resonance in Porous Media Division of Groupement Ampere. He has published over 160 papers and holds over 60 patents. His research focuses on developing NMR/MRI/NQR methodologies and instrumentation for diverse applications.
