| Zusammenfassung | For determining the measurement uncertainty of dimensional computed tomography (CT) measurements with computer simulation, it is essential to verify the compatibility of the simulation with its real counterpart. A study of repeated CT measurements of a calibrated aluminum hole plate was performed and simulated. An important indicator for a sufficiently good digital representation is the metrological agreement of commonly used dimensional measurands, such as diameters and center-to-center distances. For a quantitative determination on how good the simulation matches its real counterpart, a test with additional checks for each measurand is presented. Results indicate in general a good matching of simulation and real measurement. The measured hole diameters demonstrate sensitivity to a variation in magnification as well as to a variation of the source spectrum. This sensitivity can also be seen in the simulated CT scans. |
