  • Method and system for magnetic resonance imaging using nitrogen-vacancy centers
    Patent number: 9702900
    Abstract: A method for performing sub-nanometer three-dimensional magnetic resonance imaging of a sample under ambient conditions using a diamond having at least one shallowly planted nitrogen-vacancy (NV) center. A driving radio-frequency (RF) signal and a microwave signal are applied to provide independent control of the NV spin and the target dark spins. A magnetic-field gradient is applied to the sample with a scanning magnetic tip to provide a narrow spatial volume in which the target dark electronic spins are on resonance with the driving RF field. The sample is controllably scanned by moving the magnetic tip to systematically bring non-resonant target dark spins into resonance with RF signal. The dark spins are measured and mapped by detecting magnetic resonance of said nitrogen-vacancy center at each of said different magnetic tip positions. The dark-spin point-spread-function for imaging the dark spins is directly measured by the NV center.
