摘要:
A method is provided for performing NMR spectroscopy. The method comprises positioning a sample in a homogeneous stationary magnetic field directed along an axis, preparing nuclei in at least a predetermined volume of the sample for resonant emission of an NMR signal and creating this NMR signal. This comprises irradiating the sample with at least one RF excitation pulse in accordance with an MRI sequence preparation and/or evolution module. The method also comprises sensing the NMR signal in the absence of frequency encoding magnetic field gradients such that analysis of the NMR signal yields a chemical shift spectrum from the nuclei. During this sensing, a plurality of intermittently blipped phase gradient pulses are applied to incrementally shift a position in k-space such that different time segments of the NMR signal, demarcated by the blipped phase gradient pulses, correspond to different predetermined locations in k-space.
