Installation allowing the adjustment of compensating filters without exposure to permanent irradiation. According to one possible embodiment, a radiological image is taken (source, brightness or luminance amplifier) and memorized in an image memory prior to being projected by the video projector onto the patient by through-crossing the filter, this filter having brightness absorption and X-ray absorption properties which are similar.
