Abstract

This paper describes on-going research into 3-D x-ray imaging techniques conducted by the 3- D Imaging Group at The Nottingham Trent University. This work was initiated to enhance the visual interpretation of complex x-ray images, specifically in response to problems encountered in the routine screening of freight and hand luggage at airports. The interpretation of standard 2-D x-ray images by humans is difficult due to the lack of visual cues to depth in an image produced by transmitted radiation. The solution proposed is to introduce binocular parallax, a powerful physiological depth cue, into the resultant shadowgraph x-ray images. This is accomplished by implementing a stereoscopic imaging technique specifically developed by the Nottingham group for use with linear x-ray detector arrays and has culminated in the development of two experimental machines. Current research involves the investigation of techniques that allow the extraction of the 3-D data contained in the stereoscopic images such that `slice' images can be obtained. This data set may then be used with existing reconstruction software utilized by CAT scanning techniques.
