Abstract
A radiological system, wherein x-ray images (radiation images) are produced and are converted, through a video chain, for display as a video image, the system having a modulation transfer function, has the capability of influencing the modulation transfer function dependent on ambient light which is present at the display. To that end, a control unit is provided which provides two-dimensional control of the modulation transfer function dependent on illumination which is present in the environment of the display. The control is effected by means of a two-dimensional spatial frequency filter.
