Abstract: An x-ray system for generating x-ray images comprises an x-ray transmitting/receiving device, and an input arrangement (5) for determining the exposure parameters of an x-ray process, wherein the object to be x-rayed can be depicted on a screen surface (10) of a visual display unit (6) as a virtual model (12) in at least one position. The display unit (6) is operationally connected with the input arrangement (5) such that the exposure parameters can be adjusted as a function of the position of the model (12). In order to consider a further position of the object to be x-rayed, the display unit (6) can be actuated by means of input means (7) of a data processing system (11) such that at least one further position of the model (12) can be adjusted on the screen surface (10).
