Claim One:
1. A method for recording an X-ray image using an X-ray system, comprising an X-ray detector, an X-ray source, a system control, and a computational unit, the method comprising: using information relating to a relative direct radiation component in a reference X-ray image and information relating to at least one of: the recording geometry utilized for the reference X-ray image; the primary X-ray dose utilized for the reference X-ray image; and the filtering utilized for the reference X-ray image, for determining a relaxation time, during which a ghosting effect of the X-ray detector resulting from a preceding X-ray image decays at least in part, which relaxation time is adapted to the X-ray image to be recorded, wherein the adapted relaxation time t is calculated using the formula: 
 t∝D +r D −l where D is the detector dose, r D is the relative direct radiation component of the reference X-ray image, and l is the specific lag property of the X-ray detector; and utilizing the adapted relaxation time to actuate the recording of the X-ray image.
