First International Intercomparison of Computed Tomography Systems for Dimensional Metrology

摘要

This paper presents the preliminary results of the "CT Audit" project, which is the first international intercomparison of X-ray Computed Tomography (CT) systems for dimensional metrology. The intercomparison was organized and coordinated by the University of Padova, Italy, and involved institutions and companies in Europe, America and Asia. The interlaboratory comparison was based on the circulation of four calibrated items that were sent to each Participant together with detailed measurement procedures. The circulation involved 16 CT systems in total and was run from March 2010 to February 2011.
