Evaluation of Volumetric Data for Dimensional X-Ray Computed Tomography

Abstract:

The measurement capability of the dimensional X-ray Computed Tomography (DXCT) is studied by a computer simulation and the result was compared to the observed data obtained by the measurement of calibrated gauges of same shape that consist of simple geometric forms. The simulation showed that the measurement using polychromatic x-ray is different from that of monochromatic x-ray, but the difference was far smaller than expected from the results of observed data. These results indicated that the deviation of the measured values of geometric objects was not caused by simple origin and more causes have to be taken into consideration for the actual apparatus.
