    Abstract: A method for the automatic determination of a contrast agent protocol for a contrast agent-enhanced medical imaging method is described. The method includes an overview recording of a region of interest of an object under examination. In addition, an image recording protocol including a plurality of recording parameters is defined on the basis of the overview recording. Furthermore, recording time points are determined for a plurality of z-positions of the region of interest on the basis of the image recording protocol. In addition, the structures acquired with the overview recording are assigned to the recording time points determined. Finally, a contrast agent protocol including the temporal course of a contrast agent injection curve is defined as a function of the acquired structures and the assigned recording time points. A contrast agent protocol determination device is also described, as well as an imaging medicinal device.

    Abstract: 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.
