In one embodiment, a system and method for inspecting a substance to detect and identify predetermined foreign element(s) in the substance. The foreign element may carry X-ray responding material compositions, emitting X-ray signals in response to primary exciting X-ray or Gamma-ray radiation. The inspection is performed during a relative displacement between the substance and an inspection zone, defined by an overlap region between a solid angle of emission of an X-ray/Gamma-ray source and a solid angle of detection of X-ray radiation, along a predetermined movement path, as the substance moves along said path, the detected X-ray radiation includes X-ray response signals from successive portions of the substance propagating towards, through, and out of said overlap region. Measured data indicative of X-ray response signals is analyzed to identify a signal variation pattern over time indicative of a location of at least one foreign element carrying an X-ray responsive marker.

Systems and methods for robotic inspection of above-ground pipelines are disclosed. Embodiments may include a robotic crawler having a plurality of motors that are individually controllable for improved positioning on the pipeline to facilitate image acquisition. Embodiments may also include mounting systems to house and carry imaging equipment configured to capture image data simultaneously from a plurality of angles. Such mounting systems may be adjustable to account for different sizes of pipes (e.g., 2-40+ inches), and may be configured to account for traversing various pipe support structures. Still further, mounting systems may include quick-release members to allow for removal and re-mounting of imaging equipment when traversing support structures. In other aspects, embodiments may be directed toward control systems for the robotic crawler which assist in the navigation and image capture capabilities of the crawler.

Embodiments provide a stationary X-ray source for a multisource X-ray imaging system for tomographic imaging. The stationary X-ray source includes an array of thermionic cathodes and, in most embodiments a rotating anode. The anode rotates about a rotation axis, however the anode is stationary in the horizontal or vertical dimensions (e.g. about axes perpendicular to the rotation axis). The elimination of mechanical motion improves the image quality by elimination of mechanical vibration and source motion; simplifies system design that reduces system size and cost; increases angular coverage with no increase in scan time; and results in short scan times to, in medical some medical imaging applications, reduce patient-motion-induced blurring.

There is presented an apparatus for identifying a sample. Such an apparatus may be used to detect unwanted items as part of a security screening system. The apparatus includes a platform for receiving the sample, at least one electromagnetic radiation emitter, a plurality of detectors and a calculator. The electromagnetic radiation emitter is adapted to provide a plurality of conical shells of radiation. Each conical shell has a characteristic propagation axis associated with it. The detectors are arranged to detect radiation diffracted by the sample upon incidence of one or more conical shells of radiation. Each detector is located on the characteristic propagation axis associated with a corresponding conical shell. The calculator is adapted to calculate a parameter of the sample based on the detected diffracted radiation. The parameter includes a lattice spacing of the sample.

A system and method for X-ray computed tomography includes a robotic arm that moves an X-ray emitter around a subject in a curvilinear path and an X-ray detector that captures 2-dimensional views while the subject is scanned. Movements of the emitter and detector are coordinated such that the position and angle of the emitter relative to the detector remains substantially constant during scanning. A processor uses computed tomography to reconstruct an image of the subject from the captured 2-dimensional views. The robotic arm varies the pitch of the X-ray emitter during the scan to enhance the spatial resolution of the reconstructed image. The processor generates a projection transformation matrix based on movement of the robotic arm for each captured 2-dimensional view that is applied during reconstruction.
