Method and device for inspection of liquid articles
Disclosed are a method and a device for security-inspection of liquid articles with dual-energy ct imaging. The method comprises the steps of obtaining one or more ct images including physical attributes of liquid article to be inspected by ct scanning and a dual-energy reconstruction method; acquiring the physical attributes of each liquid article from the ct image; and determining whether there are drugs concealed in the inspected liquid article based on the difference between the acquired physical attributes and reference physical attributes of the inspected liquid article.

Sparse and energy discriminating collimated detector elements to assist scatter evaluation in ct imaging
A computed-tomography apparatus that includes a ct scanner including an x-ray source and a detector covering respective angle ranges in the axial and transaxial planes of the ct scanner. The ct detector includes first detector elements disposed on a first surface to capture incident x-ray photons emitted from the x-ray source, and second detector elements sparsely disposed on a second surface different from the first surface, the second surface being farther away from the scanner than the first surface, the second detector elements being smaller in number than the first detector elements.
