Claim:
1. A method for presenting image data, in which the position of an optical instrument is captured and positional information is obtained thus and, with the aid of the positional information, image data are determined and displayed or processed further, wherein the position of the optical instrument is captured by a position capturing apparatus comprising a field generator for an alternating electromagnetic field and sensor coils which are attached to the instrument, wherein the image data to be displayed are at least in part based on virtual image data, which are not captured directly by the optical instrument, which image data represent an object or body part situated in a field of view of the optical instrument, wherein, in which the optical instrument has a viewing direction and image data to be presented are determined from the virtual image data taking into account the viewing direction of the optical instrument and wherein covered structures are presented in the real image data in a superposed fashion by virtue of contours of the covered structures being plotted in the real image data in the right perspective.
