Abstract:
1. A method for producing an image sequence comprising the steps of: determining a first set of deformation vectors that maps volume elements of a first volume dataset of an examination subject onto volume elements of a second volume dataset of said examination subject, acquired at a point in time different from said first volume dataset; determining a second set of deformation vectors that maps volume elements of the second volume dataset onto volume elements of the first dataset; producing a first set of intermediate volume datasets comprising i intermediate volume datasets by, for each intermediate volume dataset in said first set of intermediate volume datasets, calculating a first attenuated deformation vector from a weighting of the deformation vectors of said first set of deformation vectors with a deformation factor A producing a second set of intermediate volume datasets comprising i intermediate volume datasets by, for each of said intermediate volume datasets in said second set of intermediate volume datasets, calculating an attenuated deformation vector from a weighting of the deformation vectors of said second set of deformation vectors with a deformation factor B producing a set of dissolve volume datasets by, for a first of said pairs of corresponding intermediate datasets, multiplying a first intermediate volume dataset in the first of said pairs by a factor k=(1−A sorting said dissolve volume datasets according to increasing A displaying said dissolve volume datasets in said sequence.
