Abstract
A tray for holding a material while the material is being subjected to penetrating radiation. The tray has a surface on which the material rests while subjected to penetrating radiation. The surface has at least two areas, namely a first area and a second area, the first and second areas characterized by first and second signatures, respectively when exposed to penetrating radiation, wherein the first signature is different from the second signature.

50. ) Method for performing security screening at a checkpoint, including:
-
a) placing a liquid product in a tray having at least two reference areas manifesting respective X-ray signatures when exposed to X-rays, the X-ray signatures being distinguishable from one another; b) performing an X-ray inspection of the tray while the tray holds the liquid product, the X-ray inspection including deriving the X-ray signatures; c) determining if the liquid product is a security threat based at least in part on the X-ray signatures. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57)

58. ) Method for performing security screening at a checkpoint, including:
-
a) providing an X-ray imaging system having a scanning area; b) 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; c) placing an article to be scanned on the supporting device; d) introducing the article to be scanned in the scanning area while the article is supported by the supporting device; e) based at least in part on the X-ray imaging system, deriving the X-ray signatures of the reference areas and obtaining an X-ray image of the article while the article is supported on the supporting device; f) determining if the article is a security threat based at least in part on the X-ray signatures. - View Dependent Claims (59, 60, 61, 62, 63, 64, 65, 66, 67, 68)

69. ) A method for performing security screening on a plurality of liquid products at a security checkpoint, comprising:
-
a) providing an X-ray imaging system having a scanning area; b) providing a supporting device for supporting a liquid product during a scanning cycle performed with the X-ray imaging system on the liquid product, the supporting device including at least one reference material manifesting an X-ray signature in response to exposure to X-rays; c) using the supporting device to perform a succession of scanning cycles on respective ones of the liquid products; d) wherein each scanning cycle includes; i) deriving the X-ray signature of the reference material; ii) performing a self-calibration of the X-ray imaging system based at least in part on the X-ray signature; iii) determining if the self-calibrated X-ray imaging system is a security threat. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76)

77. ) A method for performing security screening on liquid products, comprising;
-
a) scanning the liquid product and a reference material with an X-ray imaging system, the reference material being characterized by an X-ray signature, the scanning generating X-ray image data of the liquid product and of the reference material; b) deriving the X-ray signature from the X-ray image data; c) performing a self-calibration of the X-ray imaging system based at least in part on the X-ray signature; d) determining with the self-calibrated imaging system if the liquid product is a security threat. - View Dependent Claims (78, 79, 80)

96. ) An X-ray inspection station for performing security screening on liquid products, the X-ray inspection station comprising:
-
a) an X-ray scanning area where one or more liquid products are exposed to X-rays; b) a supporting device for supporting one or more liquid products while the liquid products are exposed to X-rays in the scanning area; c) a computer based processing unit; responsive to an interaction between X-rays and the supporting device to perform self-calibration for processing X-ray image data of the one or more liquid products to determine if the one or more liquid products are a security threat. - View Dependent Claims (97, 98, 99, 100)
