This high-tech scanner uses scattered X-ray signals and high-resolution 3D X-ray images to scan the object in depth, and it can also partially rotate around the object to see its surrounding and behind.
The scanner generates a color image to indicate the type of material through which the rays pass through the object, further increasing the probability of detecting and determining that there may be a threatening object.
Paul Evans, a professor of applied image science at Nottingham Trent University, said: "We have a brand new concept that enhances the X-ray signal. New geometric images have given impetus to this, and we can produce new types of 3D scans to determine and Distinguish between material and material. It is a system that can identify a material more accurately than currently used elemental color collection technology. "
He added: “Machine operators at British airports inspect millions of packages each year, and this enhanced signal scanner will greatly speed up security screening and scan a piece of luggage in seconds. It also helps Reduce the number of false alarms. "
Current shadowing techniques—photographic techniques that use radiation to form images on radiation-sensitive surfaces—cannot examine the front, back, and middle of an object. A computerized axial plane X-ray (CAT) scanner can form a three-dimensional model of an object, but it is too large, slow, and expensive to maintain.
Professor Keith Rogers, director of the Materials Science and Engineering Center at the University of Greenfield in Bedford, England, said: "The identification of materials will be more precise, and only our new X-ray optical elements can do this. We are still in development Early stage, but hope that this technology will not only work in security scans, but also in medical imaging. "
It is reported that researchers at the School of Science and Technology at Nottingham Trent University have jointly applied for a patent on the scanner with the University of Glenfield and are cooperating on this project. The research team is also working closely with the Office of Science and Technology Development of the UK Home Office and the US Department of Homeland Security on this project.
