A Discussion on Performance Verification of 3D X-Ray Computed Tomography Systems

Computed tomography capability of scanning internal and external surfaces makes it a valuable emerging technology to inspect geometrically complex products, e.g. those manufactured by additive technologies. However, traceability is still an issue due to the lack of well-established methodologies. In this work, we will discuss the problems encountered defining the procedures to test two 3D X-Ray CT systems. The required artifacts comply with the VDI/VDE 2617 part 13 standard but are as simple as possible to ease manufacturing and calibration. The artifacts and procedures may be useful for both measuring system manufacturers and users to ensure measurement traceability.
