<p>A human body back-scattering inspection system comprising a flying-spot forming unit 2 configured to output beams of X-rays 11, 12, a plurality of discrete detectors 301-304 which are arranged vertically along a human body 4 to be inspected, and a controlling unit coupled to the flying-spot forming unit and the plurality of detectors, and configured to generate a control signal to control the flying-spot forming unit and the plurality of detectors to perform a vertically partitioned synchronous scan on the human body to be inspected. The body to be inspected may be divided into an upper part and a lower part and a first detector and second detector, arranged from top to bottom, may receive a reflected beam from either the upper part or the lower part. The flying-spot unit 2 may comprise a cylinder with holes distributed in a spiral on its surface so that the beams are output in a time-sharing manner, and there may be two flying-spot units arranged along the vertical direction to independently scan the upper part and lower part of the body.</p> |
