An intuitively manageable method for adjusting at least one parameter (X) that determines the image quality of an X-ray image produced by an X-ray device (1) is provided, wherein, on a user interface (18) of the X-ray device (1) a setting zone (25) for the parameter (X) is shown pictorially, and in relation to the setting zone (25) the current setting (X.sub.act) of the parameter (X) is likewise shown pictorially. At least two sub-zones (32, 33, 34) of the setting zone (25) are differentiated from each other by color, wherein a first sub-zone (32) corresponds to a parameter-setting that guarantees good image quality and a second sub-zone (34) corresponds to a parameter-setting that is critical for the image quality.
