Filed:

Aug 7, 2007

Appl. No.:

11/834888

Inventors:

Peter J. Rothschild - Boston MA, US
Jeffrey R. Schubert - Somerville MA, US
Aaron D. Pailes - Acton MA, US

Assignee:

American Science and Engineering, Inc. - Billerica MA

International Classification:

G01N 23/20

US Classification:

378 90, 378 57

Abstract:

An X-ray imaging inspection system for bags and packages. Transmission imaging is performed using a fan beam and a segmented detector, while scatter imaging is performed with a scanned pencil beam, with both beams active simultaneously. Cross-talk between the beams is mitigated by a combination of shielding, scatter detector design, positioning and orientation, and image processing. Image processing subtracts the measured radiation scattered from the transmission beam into the scatter detectors, reducing cross-talk.

US Classification:

378 90, 378 87, 378 88, 378146, 378196, 378197

Abstract:

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-á-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.

Abstract:

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-à-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.

US Classification:

378160000, 378087000, 378057000

Abstract:

Apparatus and methods that permit an operator of a backscatter x-ray system to shine a search light on a closed container or vehicle, and then image the contents of that container in a region roughly corresponding to the area of the container covered by the search light. A display near the operator presents the backscatter image of the container contents.

International Classification:

G01N 23/04

US Classification:

378057000

Abstract:

Systems and methods for inspecting an object with a scanned beam of penetrating radiation are disclosed. Scattered radiation from the beam is detected, in either the backward or forward direction. Characteristic values of the backscattered radiation are compared to expected reference values to characterize the object. Additionally, penetrating radiation transmitted through the inspected object may be combined with scatter information. In certain embodiments, the inspected field of view is less than 0.1 steradians, and the detector is separate from the source of penetrating radiation and is disposed, with respect to the object, such as to subtend greater than 0.5 steradians in the field of view of the object.

International Classification:

G01N 23/04
G01N 23/201

US Classification:

378 57, 378 87

Abstract:

An inspection system, and inspection methods, based upon an imaging enclosure characterized by an enclosing body. A source of penetrating radiation and a detector module are concealed entirely within the body of a conveyance such as a trailer. A characterizing value or an image is formed with respect to an inspected object that is disposed entirely outside the conveyance and the characterizing value or image is made available to a remotely disposed operator. Additional detectors may be disposed distally to the inspected object and may detect transmitted, or forward-scattered, penetrating radiation.
