  • Spatially selective nuclear magnetic resonance pulse sequences
    Patent number: 4710718
    Abstract: Increased spatial sensitivity (FIGS. 4) or spatial tolerance (FIGS. 1) in selectively manipulated NMR sample analysis is excited from a spatially inhomogeneous FR field using pulse sequences which operate to exclude all spins deviating from a selected initial orientation (FIGS. 4 and 5) or to inclusively extend the applicable flip angles over a range of initial spin orientation (FIGS. 1).
