Doctoral dissertation, Harvard University.http://dissertations.umi.com/gsas.harvard:11544http://nrs.harvard.edu/urn-3:HUL.InstRepos:12274105Magnetic resonance imaging (MRI) has revolutionized modern medicine by providing non-invasive, chemically selective, three-dimensional imaging of living organisms. Industrial-scale MRI has the capability to image with millimeter-scale spatial resolution and has the sensitivity to detect as few as \(10^{14}\) nuclear spins. Increasing spatial resolution to the atomic scale and sensitivity to the single-spin level would enable a wide array of applications most notably including imaging molecular structur. However, conventional MRI methods are already highly optimized, and further order-of-magnitude-scale improvements cannot be reasonably expected without employing fundamentally different technologies.en-USPhysicsThesis or Dissertation2014-06-06
