Abstract
A multiple-view-angle cargo security inspection method for inspecting an object using a cargo security inspection system, the cargo security inspection system including a radiation source for generating a beam of rays for transmitting through the object to be inspected and a data collecting unit for collecting the transmission projection data after the beam of rays has transmitted through the inspected object, the method including a scanning step including: rotating the radiation source and/or the object about a rotation axis so as to achieve a relative rotation, thereby positioning the radiation source in a plurality of discrete positions with different view angles with respect to the inspected object, wherein, in each view angle, the radiation source moves along a straight line in a direction parallel to the rotation axis and at the same time scans the inspected object so as to acquire the transmission projection data at each view angle.
