Method for two-dimensional or three-dimensional imaging of an examination region and arrangement for carrying out the method

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 picked up with various measuring parameters and different sets containing raw data picked up with the same measuring parameters. In this case, improved temporal resolution is achieved in that, in order to generate 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, and in that the auxiliary data are derived by interpolation of raw data determined, in each case, from the same measuring parameters but at different measuring time points, in that the weight with which the raw data are included in the interpolation is proportionately larger the smaller the temporal separation between the corresponding measuring time point and the selectable time point, and in that the image of the determination region is reconstructed from the set of auxiliary data. <IMAGE>
