Abstract:
1. An X-ray system for creating diagnostic representations of a patient, the X-ray system being capable of selecting different operating parameters at least with respect to the energy spectrum used for the X-ray radiation, the X-ray system comprising: an X-ray tube to produce a beam composed of X-rays with an energy spectrum to scan the patient; a detector to measure attenuation of the X-ray radiation passing through the patient; an application unit to provide contrast medium, the contrast medium providing contrast in the X-ray representation of the patient; a control and computation unit to control the X-ray system and create the X-ray representations of the patient with the aid of stored and executed computer programs; and a selection means which, after direct or indirect statement of the parameters, presets at least one combination of contrast medium and energy spectrum of the X-ray radiation for the examination, by means of which an optimum contrast-to-noise ratio is achieved in the examination area, the parameters including at least examination volume and tissue structure.
