Abstract: The disclosure provides a vehicle inspection system which comprises a scanning device and a vehicle transmission device extending through a scanning area of the scanning device. The vehicle transmission device is configured to drive a vehicle being inspected through the scanning area, and comprises an initial driving section located upstream of the scanning area along the moving direction of the vehicle being inspected and a self-moving section arranged downstream of the initial driving section; the initial driving section is configured to drive the vehicle being inspected to move towards the scanning device and enable the vehicle being inspected to have an initial speed upon termination of driving; the self-moving section is configured to allow the vehicle being inspected to move on by itself after termination of driving so that the vehicle being inspected will entirely pass through the scanning area. The vehicle inspection system has the advantages of simple structure and low cost.

Abstract: 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 non-uniform 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.
