  • Patent number: 10989819
    Abstract: The invention relates to a gamma radiation detector that provides compensation for the parallax effect. The gamma radiation detector includes a plurality of scintillator elements, a planar optical detector array, and a pinhole collimator that includes a pinhole aperture. Each scintillator element has a gamma radiation receiving face and an opposing scintillation light output face.

  • Patent number: 10983072
    Abstract: The invention relates to a method for dimensional measurement by way of X-ray computed tomography, featuring the steps (a) Irradiating a test object (26) with non-monochromatic X-ray radiation from a virtually punctiform X-ray source (12), (b) measuring the intensity (I) of the X-ray radiation (22) in the radiation path behind the test object (26) by means of a detector (14) which has a plurality of pixels (P) to obtain pixel-dependent intensity data (I(P)), and (c) calculating at least one dimension (H) of the test object (26) using the pixel-dependent intensity data (I(P)). According to the invention, the pixel-dependent intensity data (I(P)) is corrected by the influence of an effective penetration depth (?) on the detector and/or a displacement of the effective source location (Q) on a target (20) of the X-ray source (12).

  • Patent number: 10983071
    Abstract: The present invention relates to a photon scanning apparatus comprising a photon source (2) to emit a photon beam (4), a photon detector (6) to detect photons emitted from the photon source (2). The photon source (2) is adapted to emit the photon beam (4) in accordance with a predetermined pulse width modulation scheme at a predetermined flux rate, wherein the pulse width modulation scheme defines pulse widths of the photon beam (4) for respective positions of the photon source (2) and the photon detector around a central axis (R) and an object to be scanned. The photon detector (6) is adapted to start detecting photons with a delay relative to the photon source starting to emit photons and to finish detecting photons prior to the photon source stopping to emit photons. The photon scanning apparatus thus only has to be calibrated for the predetermined flux rate.
