A control device (4) for a medical imaging system drives a signal source (1) and a detector (2) so that the detector (2) registers raw data of an object (5). Said device accepts the registered raw data and conveys send data corresponding to said registered raw data via a computer-to-computer link (10) to a computing device (11) not assigned to the medical imaging system. Said device determines an end data record by means of the send data and conveys it to the control device (4) via the computer-to-computer link (10). At least one end image is defined by the end data record. The control device (4) feeds out the end image to a user (15) of the medical imaging system via a viewing device (16).
