Paper Abstract

The interpretation of standard 2D X-ray images by humans is often very difficult due to the lack of visual cues to depth in an image produced by transmitted radiation. The 3D Imaging Group has previously developed stereoscopic X-ray systems providing binocular parallax as a depth cue to aid images interpretation. The stereoscopic images produced have proven suitable for human viewing and allow the observer to determine the relative position of objects within the scene under consideration. Such additional information is useful for scene interpretation and understanding. The binocular parallax introduced into X-ray images can be utilized in a similar way to television type stereoscopic systems where the disparity is used to determine the range of objects within the scene. This range information can be used in a number of ways, for instance co-ordinate measurement. Current research at Nottingham has concentrated on grouping object points of similar depth and producing a series of contiguous slices through the scene of interest. The purpose of producing this new data base is to combine this and existing reconstruction software used in CAT scanning techniques to provide a 21/2D visualization of the observed scene or object. This representation of the scene is intended to introduce an alternative view to the observer, further enhancing their interpretation ability.
