摘要: An object within a region is exposed to a first beam of penetrating radiation. The first beam of penetrating radiation is sensed on a side opposite the region from a source of the first beam. An attenuation of the first beam caused by passing the first beam through the object is determined, the attenuation is compared to a threshold attenuation. If the attenuation exceeds the threshold attenuation, a parameter of a second of beam of penetrating radiation is adjusted based on the determined attenuation.

摘要: A source of pulsed radiation is coupled to a positionable filter. The positionable filter includes an element that produces an indication of a position of the filter. The source is configured to receive the indication of the position of the filter, and to regulate emission of a pulse of radiation based on the indication. A device includes an area including a material that alters a parameter of a beam of radiation that interacts with the material. The device is configured to move relative to a source of pulsed radiation. An element provides a signal to the source of pulsed radiation that indicates a position of the area relative to the source. The signal causes the source to trigger emission of a pulse at a time such that the emitted pulse is incident upon a portion of the area.

摘要: Apparatus for scanning large cargo to detect concealed contents include a mobile platform configured to carry and position at least one X-ray or gamma-ray source and at least one detector array at a plurality of positions with respect to a stationary cargo. The detector array may be mounted on a boom moveably affixed to the mobile platform. Multiple measurements of radiation passing through the cargo for various source-detector orientations can be used to compute volumetric images of concealed content within the cargo.
