Computed tomography (CT) scans are moving out of hospitals and into factories. Advances in the technique mean that it can increasingly be used to measure product dimensions and surface features. While industrial CT measurement remains time consuming and prone to considerable error, it can simultaneously evaluate both the complete inner and outer geometry of a sample without causing it any damage. This could substantially improve product development and quality control, but quicker and more accurate techniques are needed to provide practical CT scanning that can be integrated into production lines.
This project will significantly enhance the quality and efficiency of measurements performed using CT. By correcting geometry errors by 9 degrees of freedom and those originating in the X-ray tube and detector, the project will improve CT accuracy by a factor of 2-8. It will also produce fast CT methods to reduce measurement time to a few minutes or less, greatly benefiting advanced manufacturing in areas such as the automotive, aerospace, and telecoms industries.
