A raw data set is acquired using a scan protocol via an imaging medical device. In an embodiment of a method, the raw data set and the scan protocol are transmitted from the medical device to a reconstruction unit. Furthermore, an at least two-dimensional image data set is calculated from the raw data set via the reconstruction unit. Furthermore, a display parameter is fetched via the reconstruction unit, the display parameter being assigned to the scan protocol and the display parameter defining a first projection method for the image data set. Furthermore, the image data set and the display parameter are transmitted from the reconstruction unit to a display unit, the reconstruction unit and the display unit being spatially separate. Furthermore, a first projection data set is determined by applying the first projection method to the image data set via the display unit.
