ABSTRACT:
In a method for producing an image sequence on the basis of two volume datasets that were acquired at different points in time, a first set of deformation vectors is determined that maps image contents of the first volume dataset onto image contents of the second volume datasets, subsequently a second set of deformation vectors is determined that maps image contents of the second volume dataset onto image contents of the first volume dataset. Subsequently, sets of intermediate volume datasets are produced using attenuated deformation vectors with deformation factors Aiand Bi. Dependent on the size of the deformation factors, the image information of the individual intermediate volume datasets are shifted to different degrees in relationship to the corresponding volume dataset. Subsequently, a set of dissolve volume datasets is produced and displayed as an image sequence.
