摘要

The invention relates to a method for two-dimensional or three-dimensional imaging of an examination region, in which a set of raw data is repeatedly measured, it being possible to reconstruct an image of the examination region from each set and the raw data of a set being acquired with various measurement parameters and different sets containing raw data acquired with the same measurement parameters. In this case, improved temporal resolution is achieved in that, in order to produce an image representing the examination region at a selectable time point, from at least two sets of raw data, a set of auxiliary data is formed, in that the auxiliary data are derived by interpolation of raw data, determined from the same measurement parameters in each case, but at different measurement time points, in that the weighting with which the raw data are input into the interpolation is commensurately larger, the smaller the temporal separation between the associated measurement time point and the selectable time point, and in that the image of the examination region is reconstructed from the set of auxiliary data.
