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 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.
