Estimating the term…
A method for performing security screening at a checkpoint is provided. The method includes providing an X-ray imaging system having a scanning area and providing a supporting device for supporting articles to be scanned in the scanning area, wherein the supporting device has at least two reference areas manifesting respective X-ray signatures when exposed to X-rays, the X-ray signatures being distinguishable from one another. The method further includes placing an article to be scanned on the supporting device, introducing the article to be scanned in the scanning area while the article is supported by the supporting device and using the X-ray imaging system for deriving the X-ray signatures of the reference areas and for obtaining an X-ray image of the article while the supporting device is in the scanning area. The method further includes using the X-ray signatures to derive X-ray attenuation information from the X-ray image and using the X-ray attenuation information in determining if the article is a security threat.
A method for performing security screening at a checkpoint, including:
An X-ray inspection station for performing security screening on articles, the X-ray inspection station comprising:
A tray for supporting an article while the article is subjected to an X-ray inspection in an X-ray imaging apparatus, the X-ray imaging apparatus including an array of X-ray detectors, the tray including at least two reference areas manifesting respective X-ray signatures that are distinguishable from one another, at least one of the reference areas having an extent such that X-rays passing through the reference area are received by a majority of the X-ray detectors of the array of X-ray detectors.
A belt for carrying an article to be subjected to an X-ray inspection in and out of the scanning area of an X-ray imaging apparatus, the belt including at least two reference areas manifesting respective X-ray signatures when exposed to X-rays, the X-ray signatures being distinguishable from one another.
