Stereo Viewing without dedicated glasses: A new approach to visualize large 3D-MR and Volume CT Datasets

摘要

3D MR and Volume-CT data sets require new tools for visualization such as the "Stereo Viewing". Initial implementations required the use of dedicated glasses to obtain the stereoscopic effect. Recently, a new technique has been developed by 4D-Vision~(TM), Jena, Germany, which enables spatial viewing glasses-free. This new technique is based on a regular 15" TFT-flat-screen monitor equipped with a special filter system. This configuration allows the display of objects from minimum eight different angles with a shift of one degree in between. Of these eight perspectives provided only two reach the- eyes of a viewer at one time. Different viewers in front of the screen obtain different perspectives resulting in a spatial view for all viewers in front of the monitor. To demonstrate 3D data sets, a 69" plasma display equipped with the "Stereo Viewing" panel is also used. This stereoscopic presentation mode can be employed for still images and movies, e.g. AVI files. The described system was evaluated over a period of eighteen months.
