摘要：
A method is described for determining the velocity of a fluid in a region to be investigated using an imaging method, preferably computer tomography, of an investigation object. In the method, a plurality of separately spaced sub regions of a region to be investigated, through which sub regions the fluid is flowing, are defined. Time-dependent image data is produced for the plurality of separately spaced sub regions. Moreover, time/density curves are produced with, in each case, a plurality of time-dependent intensity values on the basis of the time-dependent image data for the separately spaced sub regions. Additionally, the time displacement in the time/density curves is determined. Lastly, the fluid velocity is determined on the basis of the time displacement determined in the time/density curves. A fluid velocity determination device is also described. Moreover, a computer tomography system is described.
