Technology Lecture on High Energy Computed Tomography (CT) Development and Applications

Date: 04 Mar 2010 - 04 Mar 2010

Venue: SIMTech Training Room, Level 3

Microfocus X-ray Computed Tomography (CT) is a non-destructive technique for creating highly detailed 3D computer models of the interior structure of objects. This allows accurate dimensional measurements to be made as well as the study of density variations, cracks, voids and other defects within the scanned objects. Recent advances in high voltage and high power X-ray source technology have reduced scan times and allowed larger denser objects to be inspected. The use of graphics card computing power has dramatically reduced CT reconstruction time. 2D fan-beam CT, used for highly scattering and diffracting samples, allows samples which cannot be scanned using 3D cone-beam CT to be inspected. Nikon Metrology has many years of experience in this field and offer a range of CT systems covering a size range from the sub-micron to over half a metre. Some practical examples of the use of microfocus CT in the automotive and aerospace industries will be presented, together with some interesting examples from other fields. This lecture is co-organised by Nikon Metrology and Crest Innovation (S) Pte Ltd.

About the Speaker
Andrew Ramsey graduated from the University of Cambridge in 1986 and joined Harwell Laboratory near Oxford to develop software for NDT data analysis. He has worked in X-ray computed tomography (CT) since 1992, to help develop one of the world’s first PC-based CT systems. While at Harwell, he worked closely with X-Tek Systems and subsequently joined them in 1999 as a software engineer to develop X-Tek’s CT reconstruction software. Andrew moved on to the Sales Department in 2006 and was responsible for worldwide technical support as well as in promoting CT technology. Following the acquisition of X-Tek by Metris and subsequently by Nikon, Andrew is now part of the X-ray Centre of Excellence and continues to support agents, sales staff and customers worldwide in CT systems.
