Abstract: A method for the merged display of first image information captured using a first imaging device with second image information captured using a second imaging device is provided. The first imaging device records fluorescence images of the area under examination. A second 3D image data record of the area under examination is recorded using an examination procedure based on electromagnetic radiation, such as computer tomography (CT) or magnetic resonance imaging (MRI). The 3D fluorescence image data record and the second 3D image data record are registered with one another, and one or more fluorescence-optically marked, relevant areas of the examination volume, on the basis of the mapping rules determined by the registration process, are displayed on a monitor.

Abstract: A device for reproducing three-dimensional data has a plurality of image points(7) that include a plurality of laser light sources(2), in front of which is arranged a lens(4). Since the laser light sources(2) of an image point(7) radiate in different directions, different images can be projected in different radiation directions(12, 13). Since eyes (10, 11) of an observer perceive different images depending on the viewing direction, a spatial visual impression is produced.
