Abstract
A computer receives a volume data set describing a vascular system with local three-dimensional resolution and a temporal sequence of groups of x-ray images. An acquisition time is assigned to each group of x-ray images comprising at least one x-ray image. Each x-ray image shows an actual presence distribution with local two-dimensional resolution for a substance in the vascular system, as defined at the respective acquisition time. The computer uses an initial presence distribution with local three-dimensional resolution for the substance, as defined for a start time, to determine further presence distributions with local three-dimensional resolution for the substance automatically for determination times by iterative resolution of fluid dynamics movement equations, which are per se location-independent. It automatically corrects the further presence distributions, if their respective determination time corresponds to one of the acquisition times, based on the temporally corresponding group of x-ray images.
