Investigation towards simulation-based determination of measurement uncertainties for X-ray computed tomography

X-ray Computed tomography (XCT) is a common tool for the industrial purposes non-destructive testing and metrology. For latter the knowledge of measurement uncertainty is of great importance. This paper gives an overview of methods to determine the expanded measurement uncertainty for a measurand based on experiments and simulations. Furthermore, we present a simulation-based case study that demonstrates the influence of several effects on the expanded measurement uncertainty for three measurement features on a selected specimen.
