Abstract: A navigation support system for medical instruments comprises a signal processing unit with an input for real-time video image signals from an optical instrument, input for instrument position signals and access to tomography image data, and output for outputting image signals. The signal processing unit generates output image signals from the image signals, the image data and the position signals and generates the output image signals such that the real-time video image signals are displayed permanently centrally on an image display unit connected to the navigation support system in a round or oval central image display of an overall image, wherein the central image display extends at least in one direction of extension across more than half of the overall image and that the secondary images generated by tomography image data, in dependence on the instrument position signals, are displayed adjacent to or partially superimposed over the central image display.

Abstract: A method for incorporating tomographically obtained image data from a patient into a system for surgical planning and/or intraoperative navigation involves tomographic image data or image data obtained by X-ray recordings from at least one defined body area of the patient by at least one first recording appliance, wherein a first reference body having at least one surface is arranged on the patient and is recorded by the first recording appliance at the same time. The recorded image data representing the first reference body are compared with known geometric data from the first reference body in order to obtain distortion information. The recorded image data are equalized by a computation unit based on the distortion information to obtain equalized image data which have further image data from the same body area superimposed to obtain superimposed image data that is presented on a display.

Abstract: A method for presenting image data, in which an optical implement captures the position and positional information is obtained thus and, with the aid of the positional information, image data are determined and displayed or processed further. The image data to be displayed are at least in part based on virtual image data, not real image data captured directly by the optical implement. These virtual image data represent an object or body part situated in the field of view of the optical implement. Within the scope of the method, real image data are recorded by means of the optical implement, the position and/or alignment of the optical implement is captured simultaneously and positional information is derived therefrom.
