  • Patent number: 4371345
    Abstract: Display equipment gives a representation of a three-dimensional body. A series of spaced apart panels (28) are mounted to a support structure (30). Each panel (28) carries representations (40) of parts of the three-dimensional body which occur in the plane occupied by the panel. The panels are transparent or open to allow the representations carried by the different panels to be simultaneously viewed by light passing through the panels, thereby giving the effect of seeing the three-dimensional body. The equipment can be used to give a three-dimension view of the interior structure of human or animal bodies by providing cross-sectional representations of the body on the panels.
