Abstract: The disclosure relates to methods, systems, and computer program products for registering a set of X-ray images with a navigation system. In the method, by a camera, at least one image of a reference object is recorded and, on the basis thereof, a current posture of the reference object is determined. It is then checked whether this posture fulfils a specified criterion, which also on an arrangement of the reference object at least partially outside a planned reconstruction volume of the X-ray device, predicts an expected successful registration. On non-fulfillment of the criterion, a signal for adaptation of a relative alignment between the X-ray device and the reference object is automatically output. On fulfillment of the criterion, the X-ray images of the reference object are recorded, the posture of the reference object is determined, and the registration is carried out using the determined postures as reference.

Abstract: A camera image is acquired by a camera and a structure that is optically concealed in the camera image is acquired by a material-penetrating acquisition modality. A stereoscopic depth location of a common reference point is then fixed at a predetermined value. The stereoscopic representation is then generated from the camera image, and an overlay image is generated based on the concealed structure. In this case, a depth location of the camera image is fixed at the depth location of the reference point, and, as a function thereof, a depth location of the overlay image is adjusted in relation to the depth location of the reference point, such that in the stereoscopic representation, the overlay image appears realistically in front of and/or behind an optically opaque part in the recording direction of the camera image.
