Provided are an odor sniffing device () and a vehicle-mounted security inspection apparatus for a container (). The odor sniffing device () includes a primary sampling front end (), which has a vent adapter (-) having a shape matching with a vent of the ventilator of the container, so that when the primary sampling front end () fits with the ventilator, the vent adapter (-) and the vent generally cooperate to achieve fluid communication. The vehicle-mounted security inspection apparatus () may perform imaging inspection and chemical inspection simultaneously.

The present disclosure relates to the technical field of CT detection, in particular to a CT inspection system and a CT imaging method. The CT inspection system provided by the present disclosure includes a scanning device and an imaging device, wherein the scanning device having a radioactive source device and a detection device is configured to rotate at a nonuniform speed in at least partial process of scanning an object to be detected; and the imaging device generates a CT image based on effective detection data, wherein the effective detection data refer to data acquired each time the detection device rotates by a preset angle. In the present disclosure, the imaging device of the CT inspection system generates a CT image based on data acquired each time the detection device rotates by a preset angle, which, compared with traditional image collection solutions, can effectively reduce image deformation and improve accuracy of detection results.
