摘要： An x-ray source emits a cone beam to a rotating, x-ray-opaque disc with radial slots. The slots break the cone beam into fan beams that are emitted to an x-ray-opaque plate that produces a scanning x-ray pencil beam as each fan beam moves across a slit in the plate. A backscatter detector is adjacent to the plate. A collimator is adjacent. The pencil beam enters the object space through slits in the detector and collimator. The pencil beam moves rapidly in the y direction in the object space, producing backscatter x-rays from the object. The collimator only passes backscattered x-rays at a selected distance from the detector. Simultaneously, the assemblage of x-ray source, disc, plate, detector, and collimator moves slowly in the x and z directions. The backscattered x-rays passed by the collimator are processed to form planar images at various depths in the object space.

摘要： A method of improving the detection of nuclear weapons in cargo containers. The container moves through an imaging region. An x-ray source emits a cone beam through the imaging region and to two or more detector columns, each detector column defining a fan beam. This hardware combines (1) the use of at least two detector assemblies, (2) use of both the current method and the photon counting method to determine x-ray intensities, and (3) use of large detector elements to increase the measured x-ray intensity by a typical factor of 270. The x-ray intensity for a pixel is read by each detector assembly at the appropriate time and the resulting x-ray intensities from each detector assembly are summed. A method of detecting a nuclear weapon includes identifying the nuclear device as the area of the image wherein a high absorption area is surrounded by a lower absorption area.
