Mobile x-ray inspection system for large objects

a mobile x-ray inspection and large object technology, applied in the direction of material analysis, material analysis using wave/particle radiation, instruments, etc., can solve the problems of invading privacy, disruption (and in some cases damage) of property, and the penetration power of these sources is limited, and the inspection is limited to relatively small parcels and containers

Benefits of technology

[0008]The current invention extends the role of inspection by penetrating radiation to encompass large containers and over-the-road vehicles,

Problems solved by technology

The non-intrusive aspect of these inspection techniques is important; the great majority of containers do not carry contraband, and the public would not long tolerate the delays, disruption (and in some cases damage) of property, and invasions of privacy that would occur if invasive inspection means were commonly used.
Since the penetrating power of these sources is limite

Embodiment Construction

[0022]As used in this description and in the appended claims, a “cargo container” is a receptacle for the storage or transportation of goods, and includes freight pallets as well as vehicles, whether motorized or drawn, such as automobiles, the cab and trailer of a truck, railroad cars or ship-borne containers. The term “cargo container,” as used herein, further includes the structures and components of the receptacle.

[0023]The invention described herein serves to characterize materials which may be contained within a cargo container and thus not readily susceptible to visual scrutiny. The characteristics of a material which might be the object of non-invasive inspection and which lend themselves to detection using the device and method taught by the invention include, but are not limited to, electron density, atomic number, mass density, linear dimensions and shape. These characteristics are unveiled by taking advantage of the various physical processes by which penetrating radiati...

Abstract

A device for inspecting a cargo container such as a motor vehicle or freight pallet, with penetrating radiation. A source of penetrating radiation is mounted on a moveable bed, thereby allowing a beam of penetrating radiation to sweep the large container. At least one detector is also mounted on the bed, either on the side of the source or on a boom, so that, as the beam is scanned across the container, the container and any contents of the container are characterized by transmitted or scattered radiation, or both.

Description

[0001]The present application is a continuation of U.S. patent application Ser. No. 09 / 072,212, filed May 4, 1998, now U.S. Pat. No. 5,903,623 currently allowed, itself a continuation of Ser. No. 08 / 799,533, filed Feb. 12, 1997, issued as U.S. Pat. No. 5,764,683, all of which are incorporated herein by reference. The present application claims priority from U.S. provisional application No. 60 / 011,495, filed Feb. 12, 1996, also incorporated herein by reference.[0002]The U.S. Government may have a paid-up license in portions of this invention and the right in limited circumstances to require the patent owner to license others on reasonable term as provided by the terms of Contract No. N39998-97-C-5209 awarded by the U.S. Department of the Navy, and Grant No. 93-G-003 awarded by the U.S. Department of Transportation Federal Aviation Administration.FIELD OF THE INVENTION[0003]The present invention relates to the inspection of large containers by means of x-ray radiation, and more partic...
