摘要： Various embodiments of the present invention are directed towards a system and method for synchronized markers. A multiple-scanner X-ray system includes a belt passing by an upper X-ray scanner and a lower X-ray scanner. An upper belt portion is conveyed in a first direction by the upper X-ray scanner and a lower belt portion is conveyed in a second direction opposite the first direction by the lower X-ray scanner, to obtain upper and lower X-rays. A plurality of X-ray reactive markers are positionally synchronized relative to each other and the belt and conveyed by the belt to cause upper visual marker information, corresponding to a visual appearance of the upper scanned belt section, to be consistent with i) upper X-ray marker information of the upper X-ray, and ii) lower X-ray marker information of the lower X-ray.

摘要： An X-ray imaging inspection system for inspecting items comprises an X-ray source 10 extending around an imaging volume 16, and defining a plurality of source points 14 from which X-rays can be directed through the imaging volume. An X-ray detector array 12 also extends around the imaging volume 16 and is arranged to detect X-rays from the source points which have passed through the imaging volume, and to produce output signals dependent on the detected X-rays. A conveyor 20 is arranged to convey the items through the imaging volume 16.

摘要： A method for the inspection of contained flowable materials within containers, such as detecting an explosive liquid in a luggage, and an apparatus for performing the method are described. The method includes the steps of: performing a radiation scan, using X-rays or Gamma rays, of a target item container of contained flowable material in a radiation scanning system to derive a spatially distributed and spectroscopically resolved measured dataset of the intensity of radiation emergent from the target item; considering the spatially distributed and spectroscopically resolved dataset of transmitted radiation intensity to be nominally determined in accordance with a relationship: [O]·[δ]=[λ] where the operators [δ] and [λ] define, respectively, physical parameters describing the liquid and the container and the system response and the operator [O] defines the relationships between the system response and the liquid and container parameters; numerically processing the measured dataset by operator inversion in order to derive a best fit solution of: [δ]=[O]−1·[λ]; and using that derived solution to determine the threat status of the target item.
