Abstract
The work outlined in this paper is examining ways to incorporate previously determined single point uncertainties of computed tomography (CT) measurements into a suitable regression analysis in order to evaluate standard geometry elements. The goal is to determine and reduce the measurement uncertainty for the specific parameters of a geometry element by using selective point rejections based on their single point uncertainty. Examinations show that the systematic error as well as the associated uncertainties can be reduced in certain scenarios compared to the statistical interpretations of repeated (simulated) measurements without considering the single point uncertainty. Nonetheless, these results still need to be verified for different data series and measurement setups.
