Patent ID: 7499522

Claim:
A cargo security inspection system for inspecting an inspected object moving through said system, the system comprising: a mechanical conveyance unit configured to carry and convey the inspected object and to define a travel path of the inspected object in the system; a radiation-generating unit configured to generate ray beams for transmitting through the inspected object; a data collecting unit configured to collect transmission data about the ray beams subsequent to the transmission of the ray beams through the inspected object and process the transmission data; wherein: the travel path of the inspected object comprises at least two linear sub-paths that are arranged at an angle relative to each other; the data collecting unit comprises at least two detector arrays for receiving the ray beams, each detector array corresponding to a respective one of the at least two linear sub-paths, a receiving plane of each of the detector arrays being disposed parallel to the linear sub-path to which the respective detector array corresponds; and the system is configured such that, during inspection of the inspected object, the radiation-generating unit and the data collecting unit remain stationary and to cause the inspected object to travel along the travel path with unchanged orientation, the inspected object thereby being at different respective angles relative to the at least two detector arrays and thereby being penetrable by the ray beams at different angles to reach the respective detector arrays.
