X-RAY SYSTEM, AND METHOD FOR GENERATING X-RAY IMAGES
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 ).
