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.
