Coordinate Measuring with Industrial X-Ray Computed Tomography

Keywords: industrial CT, dimensional measurement, influence quantities, measurement uncertainty

Industrial computed tomography (CT) has lately experienced a distinct development with respect to the coordinate measuring technique. Numerous measuring tasks can already be solved reasonably and in competition with other measuring techniques. This article describes — by means of a special test body and selected measurands and characteristics — the dimensional measuring properties of industrial CT systems. The possible influence of different physical effects on these dimensional measurands is demonstrated. In addition, a correction method to improve the accuracy of the geometric data determined by CT is presented.
