Abstract
A novel 3D X-ray imaging technique to enhance the visual interpretation of complex X-ray images routinely encountered in aviation security applications has been developed. The 3D information is visualised as a smooth object rotation on a video display monitor. Further work enabled motion parallax to be combined with binocular parallax to produce a dynamic stereoscopic display. This imaging technique is equally applicable to both standard monochrome X-ray imaging and dual-energy X-ray imaging. The latter exploits the difference in magnitude between a high energy X-ray signal and a low energy X-ray signal to compute materials discrimination information made available to the human observer by colour encoding the resultant images. To produce the required image data an integrated dual-energy X-ray camera incorporating a novel castellated dual-energy scintillator arrangement has been developed.
