Abstract: In a method for the acquisition and evaluation of data obtained in a nuclear magnetic resonance tomography apparatus, only data for a constant sub-region of an overall dataset, that was obtained from a preceding measurement, are updated by new measured data in subsequent successive measurements (keyhole method). In order to sharply reproduce measurement subjects in the visual display which move from measurement to measurement while only slightly lengthening the registration time in comparison to a standard keyhole measurement sequence, data for difficult sub-regions of the overall dataset are additionally updated from measurement to measurement, and these sub-regions are varied in a predetermined sequence from measurement to measurement.
