A medical imaging system (100) is proposed. The system includes means (203-212) for providing a sequence of recorded input images each one offering a digital representation at a corresponding instant of a body part being perfused with a contrast agent each input image including a plurality of visualizing values each one representing a corresponding portion of the body part, and means (214-218) for associating each sequence of corresponding sets in the input images of at least one visualizing value with a model function of time the system further includes means (225-233705-740) for generating a sequence of computed images at further instants, each computed image including a plurality of further visualizing values each one being determined by an instantaneous function-value which is calculated from the associated model function at the corresponding further instant and means (239-242) for displaying the sequence of computed images.
