Abstract
An x-ray diagnostics installation for producing x-ray images has an x-ray image intensifier with an output screen on which a light image corresponding to x-rays attenuated by an examination subject is present, the light image having a dominant region of primary medical interest. A detector is provided for measuring the mean image brightness of the dominant region, the detector having an optical imaging scale. An adjustment element is provided for varying the optical imaging scale of the detector so that at least one of the position and size of the dominant region is adjustable with respect to the light image.
