Fast Fourier imaging.
A new NMR imaging technique, aiming at a reduction of the data acquisition time, is described in detail. The method is applicable in all multidimensional imaging situations where at least one spatial coordinate is resolved. Discussed at some length are the point-spread function, the required bandwidth of the NMR spectrometer, and the sampling strategy used to diminish the loss in signal-to-noise ratio. Experiments reveal that a reduction of the data acquisition time by at least a factor of four is attainable in practice.
