We characterised the displacement of a transmission X-ray tube target parallel to the beam axis due to thermal effects using interferometry. Displacements of up to 10 μm with a …
X-ray diffraction is ideal for probing the sub-surface state during complex or rapid thermomechanical loading of crystalline materials. However, challenges arise as the size of …
For X-ray tubes in lab based computed micro-tomography systems, off-focal X rays are those emitted from the source but not produced at the primary focal spot of the electron beam …

Talbot–Lau interferometry (TLI) provides additional contrast modes for x-ray imaging that are complementary to conventional absorption radiography. TLI is particularly interesting …
The reduction of motion blur in computed tomography (CT) drives the current research for multisource CT. Due to their compact nature, the current multisource systems utilize …
Background Emerging multi‐pixel X‐ray source technology enables new designs for X‐ray imaging systems. The power of multi‐pixel X‐ray sources with a fixed anode is limited by …
When Wilhelm Conrad Röntgen discovered a new type of electromagnetic radiation in 1895, which is absorbed by matter to different extents depending on material, density and …
Background The spatial resolution of new, photon counting detector (PCD) CT scanners is limited by the size of the focal spot. Smaller, brighter focal spots would melt the tungsten …
The Monte Carlo particle simulator TOPAS, the multiphysics solver COMSOL®, and several analytical radiation transport methods were employed to perform an in-depth proof …
