Xray tomography (also known as computed tomography, or CT for short) enables the complete geometry of workpieces to be captured, regardless of their complexity. Both external and internal geometries are captured. Industrial computed tomography, which was mainly limited to material testing due to a lack of sufficient accuracy, also became applicable for coordinate metrology in 2005 (Fig. 36). Due to the short measuring times for objects with many features, the use of these machines leads to a considerable acceleration of process chains and an increase in economic efficiency.
