Appl. No.:

13/235894

Inventors:

Richard Mastronardi - Medfield MA, US
Jeffrey M. Denker - Woburn MA, US

Assignee:

American Science and Engineering, Inc. - Billerica MA

International Classification:

G01N 23/04
H05G 1/64

US Classification:

378205, 378 57, 378 988

Abstract:

A scanning system and methods for inspecting contents of a container. High-energy penetrating radiation collimated into a fan beam illuminates an inspected container from one side, while a plurality of detector plates are disposed on the opposite side of the container. Each detector plate has a plurality of detector modules, each of which, in turn, is disposed on a remotely activated alignment and has multiple detector elements. A controller governs the orientation of each of the plurality of detector plates based at least on the detector signal generated by its detector elements such that each detector element of each detector module of each detector plate may be aligned to within a specified fraction of the transverse dimension of the fan beam as measured at the exit slot.

International Classification:

G01N 23/04

US Classification:

378 57

Abstract:

A mobile scanning system and methods for inspecting contents of a container. Multiple detector plates are arrayed along an arcuate member coupled to a conveyance with wheels, capable of road travel. A source generates high-energy penetrating radiation that irradiates each of the detector plates from a single position. The arcuate member is disposed, during the course of operation of the system, in a vertical plane. The system has one actuator for rotating the arcuate member about a horizontal pivot into a horizontal plane, and a second actuator for further rotating the arcuate member, once rotated into the horizontal plane, about a vertical pivot, so that the arcuate member is contained, for purposes of transport, entirely within a volume defined by a rectangular prism that does not extend horizontally outward from the conveyance beyond any of its wheels.
