摘要： Methods for a tangible image of an inspected object. An object is illuminated with at least two sources of penetrating radiation that generate respective pencil beams and define respective viewing points and view planes. Post-interaction penetrating radiation due to the respective sources is used to generate signals based on respective views of the inspected object, and thus derive information with respect to a dimension transverse to the first view plane based on the second signal. A tangible image of the inspected object is then displayed depicting information with respect at least to the first view plane and the transverse dimension.

摘要： Apparatus for interrupting and/or scanning a beam of penetrating radiation, such as for purposes of inspecting contents of a container. A source, such as an x-ray tube, generates a fan beam of radiation effectively emanating from a source axis, with the width of the fan beam collimated by a width collimator, such as a clamshell collimator. An angular collimator, stationary during the course of scanning, limits the extent of the scan, and a multi-aperture unit, such as a hoop, or a nested pair of hoops, is rotated about a central axis, and structured in such a manner that the total beam fluence incident on a target is conserved for different fields of view of the beam on the target. The central axis of hoop rotation need not coincide with the source axis.

摘要： An adjustable collimator for shaping a beam of particles, such as for purposes of inspecting contents of a container. The adjustable collimator has an obscuring element substantially opaque to passage of the particles in a propagation direction that is radial with respect to the axis of rotation of a ring of apertures. A gap in the obscuring element may be characterized by a length taken along a long dimension and a jaw spacing taken along narrow dimension, and at least one of the length of the gap and the jaw spacing is subject to adjustment, either manual or automatic. The adjustable collimator may be disposed either inside or outside the ring of apertures, and, in some embodiments, the jaw spacing may be a function of distance along the long dimension relative to an edge of the gap.

摘要： An apparatus for forming a beam of energetic particles and for scanning the beam of particles with respect to an inspected object. The apparatus has a source of energetic particles characterized by an effective beam origin and a rotating hoop having at least one aperture, such that the effective beam origin of the source is closer to the inspected object than the axis of rotation of the rotating hoop. A collimating structure disposed interior to the rotating hoop collimates emission by the source into a fan beam prior to impinging on the rotating hoop. In some embodiments, the effective beam origin may be moved with respect to the axis of rotation of the hoop.
