Description
Summary:Computed tomography (CT) is a well-established technology in medical diagnostics. For a few years now, dedicated CT systems have also been in use for dimensional measurements in industry. However, as far as the accuracy and reliability of the results is concerned, many problems are still unsolved. This paper describes concepts and first results for solving these problems. CT-specific reference standards and procedures for their application - similar to the acceptance and verification procedures of classical coordinate measuring technology - have been developed. In this paper, concepts and recent results are presented. They illustrate the technological and technical aspects and indicate the attractiveness of this new measurement technology.
