Abstract

In Computed Tomography (CT) in dimensional metrology, the numerous complex measurement process steps with various influences present a significant impact on the measurement results. For the determination of measurement uncertainty, it is therefore important to consider all of these influences. The paper discusses the possibilities of a promising approach, the numerical uncertainty determination for CT in dimensional metrology.
