High-spatial-resolutionspectroscopic NMR imaging of chemically- shifted nuclei

摘要

A method for providing a high-spatial-resolution NMR image, having resolved artifact-free NMR images of chemically-shifted nuclei, includes: forming independent NMR images having imaging components due to each of the chemically-shifted nuclei; registering and combining the images to eliminate one of the components and produce a composite image containing the other component and a negative of the other component offset by the chemical shift; and forming a resolved image of the component by processing the composite image to eliminate the negative. The resolved image may then be combined with one or more of the NMR images to produce a resolved image of the first component. The method requires only 2N projections to form the two independent N-by-N NMR images.
