    • 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 Ai and 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.
    • 在基于在不同时间点获取的两个体数据集的图像序列的制作方法中,确定将第一卷数据集的图像内容映射到第二卷数据集的图像内容上的第一组变形向量, 确定将第二卷数据集的图像内容映射到第一卷数据集的图像内容上的第二组变形向量。 随后,使用具有变形因子A i和B i i的衰减变形向量来生成中间体数据集。 取决于变形因子的大小,单个中间体数据集的图像信息与相应的体数据集相关地转移到不同程度。 随后,生成一组溶解体数据集并将其显示为图像序列。
