Active matrix flat-panel detectors have gained popularity amongst X-ray imaging systems due to their speed, resolution and high dynamic range. With appropriate shielding modern flat-panel imagers can even be used in high energy Computed Tomography (C

Kurzfassung Computertomografie (CT) ist eine bewährte Methode in den Bereichen Fehleranalyse und Qualitätskontrolle. Die Energie der hierbei benutzten Röntgenstrahlung bestimmt die Eindringtiefe der Strahlung und schränkt damit die Grösse und da

X ray computed tomography (CT) is an established method in the fields of failure analysis and quality control. The energy of the X ray beam determines the penetration length of the radiation and hereby limits the size and the density of the object th

Scattered photons are one of the main sources of image degradation in industrial X-ray computed tomography (CT). X-rays travelling through matter can undergo several different physical interactions. The four main interactions of X-rays in matter are

The paper proposes a new prior model for gray-scale images in 2D and 3D, and a pertinent algorithm for tomographic image reconstruction. Using ideas from sparse Bayesian learning, the proposed prior is a Markov random field with individual unknown va

Scattering of high energetic X ray photons causes artifacts in industrial computed tomography (CT). In particular for MeV photons the interaction cross sections for scattering processes dominate those of the photoelectric effect. In addition electron
