NDT in Aerospace : Invited Research Lecture on Latest Developments in X-ray Computed Tomography

Date: 17 May 2012 - 17 May 2012

Venue: Samantha Chan

Computed Tomography (CT) is an imaging method employing tomography where digital geometry processing is used to generate a three-dimensional image of the internals and externals of an object from a large series of two-dimensional X-ray images taken around a single axis of rotation. In non-destructive testing, X-ray computed tomography is increasingly being used for quality control, conformance testing and failure analysis.This demand has led to significant advances in a wide range of enabling technologies including alternative and customised X-ray detectors, unconventional scanning geometries and sophisticated reconstruction algorithms with intelligent artefact reduction methods. Key research topics include improvement of image quality, determination of measurement uncertainty and improved reliability and automation of defect detection.

This presentation will cover the current and ongoing work in this area at the Fraunhofer Development Centre for X-ray Technology (EZRT), Germany. EZRT is a joint department of Fraunhofer IZFP, Saarbrücken, and Fraunhofer IIS, Erlangen. The Centre has four focal points of research: X-ray sensors, computed tomography, image processing and applications, and covers all areas of work from image acquisition via 2D and 3D computed tomography up to fully automated reporting including the development of complete prototypes of X-ray inspection systems.


State-of-the-art application examples of X-ray computed tomography and associated technology developments will be presented with particular emphasis on applications to the aerospace and precision engineering industries.

About Presenters

Dr Norman Uhlmann is the Director of the Development Centre for X-ray Technology (EZRT), a joint department of both Fraunhofer IZFP, Saarbrücken, and Fraunhofer IIS, Erlangen.


Dr Uhlmann received his MSc from the Institute for Theoretical Physics at the Friedrich-Alexander University, Erlangen in 2001

with a diploma thesis entitled "Molecular dynamics simulations on halo formation in dense ion beams". He received his PhD from the same university in 2005 for work in the area of detector development for medical applications under the supervision of Prof. Dr. Anton with a thesis entitled "Simulations on the Compton Camera and development of two absorption detectors on semiconductor and scintillator basis".


He joined the research staff at Fraunhofer-IIS Development Centre for X-ray Technology in 2005. In 2007 he was appointed

Head of the group “X-ray Sensors and Monte Carlo Simulation. In 2009 he became Deputy Head of the Development Centre for X-ray Technology. Since July 2010 Dr Uhlmann has been Head of the centre.


Dr Uhlmann is active in a number of research areas including :


•                 X-ray physics, X-ray beam generation and detection (directly and indirectly converting sensors) as well as the interaction of X-rays with matter

•                 High resolution computed tomography for the structure and density analysis of materials, for material characteristics, material inspection (composites, light metals, plastics) and biology

•                 X-ray backscattering methods and small angle scattering methods for imaging and analysis of materials

•                 Installation, operation and optimization of an Electron Probe Microanalyzer (EPMA) as X-ray source with ultra-small focal spots for imaging

•                 Digital image processing, pattern recognition for extracting characteristics for classification tasks in the  automated image data analysis

•                 Radioscopy systems for various component inspection methods

•                 Tomosynthesis, laminography (method for reconstruction from incomplete data sets)


Dr Uhlmann is a member of the German Physical Society (DPG) and the German Society for Non-destructive Testing (DGZfP)

where  he serves on expert committees in radiographic inspection and computed tomography and image processing in radioscopy.


Dr Uhlmann in involved with a wide range of research collaboration including :


•                 Cluster of Excellence Engineering of Advanced Materials, FAU Erlangen-Nürnberg

•                 Chair for Adhesion and Interphases in Polymers, Prof. Dr. W. Possart, University of Saarland

•                 Institute of Theoretical and Applied Mechanics (ITAM CAS), PhD. D. Vavrik, Prague, Czech Republic

•                 Institute for Experimental and Applied Physics, CTU Czech Technical University, Ing. DrSc. Stanislav Pospisil, Prague, Czech Republic

•                 Chair for Material Science and Material Mechanics, Technische Universität München, Munich, Faculty for Mechanical Engineering, Prof. Dr. mont. Ewald Werner

•                 DLR Deutsches Zentrum für Luft- und Raumfahrt (German Aerospace Center), Institute for Material Physics in Space, Prof. Dr. Andreas Meyer



Prof Randolf Hanke concurrently holds a Professorial Chair at the University of Würzburg in X-ray Microscopy and is Deputy Director of the Fraunhofer Institute for Integrated Circuits. Prof Hanke studied Physics at the University Erlangen and received his diploma in 1988 in the field of Applied Physics and his doctor’s degree in 1996 with an external thesis at the University Erlangen. In 1989, he started as a Scientist at the Fraunhofer-Institute for Integrated Circuits IIS in Erlangen. In 1991, he became a group leader of the new established group Industrial Radioscopic Image Processing. Within the scope of this task, he was responsible for the acquisition and management of different public funded and industrial projects. In 1993, he became an Assistant Head of department and was jointly responsible for the R&D activities of the department Electronic Systems. In 1997, he was assumed his position as Managing Director of the new-founded Department for X-ray Technology. In accordance with the board of directors of the Fraunhofer Gesellschaft, this department was converted to a Fraunhofer Development Centre for X-ray Technology in 1999.


In 2001, he was awarded with the Joseph-von-Fraunhofer-Award for his contributions to the “Automation of Radioscopic Inspection of Lightweight materials”. Prof Hanke is a member of the Deutschen Gesellschaft für Zerstörungsfreie Prüfung (DGZFP) and actively committed to different workshops, scientific committees and commissions. In 2002, he got a university teaching position at the Chair for Materials for Electronics at the University Erlangen. In December 2004, Prof Hanke successfully finished his Master of Business Administration study (EMBA) at TIAS NIMBAS Graduate School of Management (Associated Institute of the University of Bradford, UK). In 2008, Prof Hanke was the first candidate, who was awarded with the new established Max-Grundig-Memorial-Award in the field of Research of new Materials and Processes.


In 1st July 2010, Prof Hanke was appointed to a professorship at the Julius-Maximilians-University Würzburg for the Chair

“X-ray Microscopy” at the Faculty of Physics and Astronomy and has organised and co-organised several international

conferences in the field of Non-destructive Testing and was an invited key note speaker at different conferences.

His Fraunhofer Research Centre currently engages approximately 130 scientists and technicians including students and part time employees.
