Abstract


A large number of influencing quantities can induce measurement deviations for dimensional measurements using computed tomography. The article describes a newly developed simulation-based correction method for computed tomography coordinate measurements. Using a steel gauge block it is demonstrated that the method can significantly reduce the deviation of the measured surface from the real form of the measurement object. The computed tomography system used has a maximum acceleration voltage of 130 kV. Therefore, a steel gauge block is a relatively challenging measurement object due to the likely occurrence of beam hardening artefacts. The results show that, for a given computed tomography system, the described method can extend the range of objects for which dimensional measurements are feasible.
