Navigation assistance system (100) for medical instruments (300, 400), comprising a signal processing unit (110), which has an input (114) for real-time video image signals from an optical instrument (400), an input (113) for instrument position signals and access to tomography image data (115), and an output (112) for outputting image signals, wherein the signal processing unit (110) is embodied to generate output image signals from the real-time video image signals, the instrument position signals and the tomography image data (115), wherein the signal processing unit (110) is furthermore embodied to generate the output image signals in such a way that the real-time video image signals are permanently displayed centrally in a round or oval central image field (210) of an overall image (220) on an image display unit (200) connected to the navigation assistance system (100), with the central image field (210) extending over more than half of the overall image (220) in at least one direction of extent, and that secondary images (230, 240, 250) generated from tomography image data (115) are depicted next to or partly overlapping the central image field (220) depending on the instrument position signals. |
