An apparatus and method for inspecting personnel or their effects. A first and second carriage each carries a source for producing a beam of penetrating radiation incident on a given subject. A positioner provides for relative motion of each beam vis-&#xe0;-vis the subject in a motion, the vertical component of which is one-way. A detector receives radiation produced by at least one of the sources after the radiation interacts with the subject.

Multiple image collection and synthesis for personnel screening

An apparatus and method for inspecting personnel or their effects. A first and second carriage each carries a source for producing a beam of penetrating radiation incident on a subject. A positioner provides for synchronized relative motion of each carriage vis-&#xe0;-vis the subject in a direction having a vertical component. A detector receives radiation produced by at least one of the sources after the radiation interacts with the subject.

An apparatus and method for enhancing an image of penetrating radiation scattered by objects concealed within a container. An image derived from penetrating radiation transmitted through the container is combined with a scatter image in regard to which it is accurately registered in such a manner as to provide enhanced visibility and photorealism of the combined image.

Transmission enhanced scatter imaging

An inspection system for inspecting a moving vehicle and for detecting material disposed within the vehicle. The system has a source for providing a generally horizontally pointing beam of penetrating radiation of specified cross-section so as to illuminate vehicles driven alongside the source of radiation. A detector arrangement, disposed between the source of radiation and the moving vehicle detects radiation from the beam scattered by any material disposed on the underside of the moving vehicle and generates a scattered radiation signal that may be used for characterizing the material disposed within the vehicle.
