1. A device for processing and presenting x-ray images, comprising: an x-ray acquisition unit that emits x-rays in an x-ray acquisition cone; an optical acquisition unit that emits light in an optical acquisition cone; said x-ray acquisition unit and said optical acquisition unit being oriented so that said x-ray acquisition cone and said optical acquisition cone are congruent; a trigger unit that activates said x-ray acquisition unit and said optical acquisition unit to simultaneously respectively acquire an x-ray image of an examination subject in said x-ray acquisition cone and an optical exposure of the same examination subject in said optical acquisition cone; a subject extraction unit supplied with said optical exposure that performs an extraction procedure selected from the group consisting of segmentation and edge extraction of the subject in said optical exposure, to produce an extracted optical exposure; and a combination unit that additively combines said x-ray image and said extracted optical exposure, to produce a combined image as an output thereof.
