Abstract:
A vehicle-mounted CT security inspection system. The vehicle-mounted CT security inspection system comprises a van truck (100) and a CT security inspection device (200), wherein the CT security inspection device (200) is arranged in a van body (110) of the van truck (100); the CT security inspection device (200) comprises a CT scanner (210), an inlet conveying mechanism (220) and an outlet conveying mechanism (230); the CT scanner (210) is used for detecting articles and outputting detection results; a longitudinal side wall (120) of the van body (110) is provided with a side opening (121); a tail side wall (130) of the van body (110) is provided with a tail opening (131); and the inlet conveying mechanism (220) and the outlet conveying mechanism (230) are respectively in communication with the tail opening (131) and the side opening (121) so as to receive articles to be detected and output the detected articles. According to the vehicle-mounted CT security inspection system, CT security inspection technology is used, and multi-dimensional information, such as the density and effective atomic number of detected objects, is obtained and used, such that detecting various drugs/explosives in luggage and raising an alarm therefor are achieved, the detection capacity is higher, the false alarm rate is lower, and the vehicle-mounted CT security inspection system has the advantages of being flexible and having a short arrangement time.
