Zusammenfassung:Computer-implemented segmentation method for segmenting a core (52) and a penumbra (53) in a four-dimensional computed tomography perfusion dataset (38) of ischemic tissue in an image region of a patient, wherein at least one parameter map (39) for at least one perfusion parameter is determined from the computed tomography perfusion dataset (38), whereafter a trained function (60) using the at least one parameter map (39) as input data determines output data comprising segmentation information (42) of the penumbra (53) and the core (52), wherein the trained function (60) uses the computed tomography perfusion dataset (38) as additional input data.
