Claim:
1. A display system compatible with a magnetic resonance imaging (MRI) apparatus disposed in a magnet room for producing a video image to a patient in an MRI magnet tunnel, the image having a three-dimensional (3D) effect, the system comprising: a video signal source for producing video image signals; an MRI-compatible 3D display responsive to said video signals and disposed within said magnet room for providing a 3D display within said magnet room, said display including RF and electromagnetic interference filtering to prevent noise from said display from affecting the quality of the images produced by said MRI apparatus, the 3D display employing FPR (Film Patterned Retarder) technology to provide separate left and right eye images to provide optical image rays having 3D image content; a mirror positioned in the MRI magnet tunnel and positioned so that the patient in the tunnel can view the 3D display; circular polarization filters of opposite sense for each patient eye and positioned so the patient views images generated by the 3D display and reflected from the mirror through the circular polarization filters to produce a 3D effect.
