    摘要： The present invention provides a CT scan security check device, comprising a radiation source and a detector which form a radiation detection area, and a conveyer mechanism which conveys a checked article along a conveying path, characterized by also comprising a multidimensional movement mechanism which makes the checked article and the radiation detection area generate a relative displacement in a vertical direction and makes the checked article rotate about a vertical axis. On the other aspect, the present invention provides a CT scan security check method, comprising the following steps: 1) making the checked article and the radiation detection area generate a relative displacement in a vertical direction and making the checked article to perform a rotation movement; 2) during the checked article passing through the radiation detection area, obtaining information data on the radiation ray through the checked article; and 3) transmitting out the information data for CT arithmetic reconstruction.. In this way, it is at least achieved to perform a check process without the rotation of the radiation source and the detector, reducing the technical difficulty and design and production cost of CT-scan-security-check, and it is further achieved to check automatically and continuously on the checked article and to speed up the procedure of CT scan security check.
