Abstract: 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. The CT scanning can be implemented by a normal CT scanning technique, or a spiral CT scanning technique. In the normal CT scanning technique, the scan position can be preset, or set by the operator with a DR image, or set by automatic analysis of the DR image.

Abstract: A method and apparatus for inspection of liquids are disclosed. The method includes inspecting a liquid with a technique selected according to whether the package of the liquid is transparent, semi-transparent or opaque. If the package is transparent or semi-transparent, a Raman spectra technique is used; if the package is opaque, a technique using an electronic scale and a barcode reader is used. In some embodiments, the Raman spectra technique and the technique using barcode reader and electronic scale can be used independently for inspection of the liquid. The inspection apparatus according to the present disclosure has advantages, such as capability of material identification, rapid examination speed, small volume, light weight, portability, low cost, freedom from radiation, and simple maintenance. The method and apparatus according to the present disclosure are suitable for safety inspection in public places having a large number, and fast flow, of people.
