PROBLEM TO BE SOLVED: To provide a sequence of volume datasets from two volume datasets acquired from one image pickup object at two different points of time, to reduce the X-ray load of a patient. SOLUTION: A first set of deformation vectors is determined to map image contents of the first volume dataset onto image contents of the second volume datasets. Subsequently, a second set of deformation vectors is determined to map image contents of the second volume datasets onto image contents of the first volume dataset. Further, sets of intermediate volume datasets are produced using attenuated deformation vectors with deformation factors A<SB>i</SB>, B<SB>i</SB>. Dependent on the size of the deformation factors, the image information of the individual intermediate volume datasets are shifted to different degrees in relation to the corresponding volume dataset. Subsequently, a set of image deformation volume dataset is produced. COPYRIGHT: (C)2004,JPO
