Data records are automatically placed in a cloud by the systems or a PACS connected to the respective system. Measurement protocols, applied doses, and anonymized images of the data records are referenced among each other. The data records placed in the cloud are assigned the respective examination type and an identification of the respective system and/or an identification of the type of respective system. The cloud accepts data queries from users.
