A nuclear magnetic resonance (NMR) imaging method in which, with the aid of a gradient system, a spatially and temporally variable magnetic field Bis generated, for the at least two-dimensional spatial encoding of NMR measurement signals in a measurement sample region to be imaged, where the magnetic field Bis employed in at least two forms Band Bin the measurement sample region to be imaged during a single measurement cycle from excitation to reading of the NMR measurement signals, where the first form Bhas essentially ns poles, where ns is an even number &#x3e; 2, and has ns essentially sectorial sub-regions, in each of which the magnetic field Bis locally monotonic in one direction, where the measurement signals from the measurement sample are recorded by means of at least ns receiver coils which have different sensitivity over the ns sub-regions of the region to be imaged, is characterized in that the second form Bis essentially identical to the first form B% with the second form Bbeing rotated by an angle &#x394;&#x3c6;, where relative to the first form B. The invention provides an NMR imaging method in which a high-resolution image of the region to be imaged is obtained more quickly utilizing the advantages of NBSEMs.
