NDT Example - Neutron Beam CT (NBCT) on Tornado jet turbine blade's cooling hole B

Acknowledgement - The Tornado jet turbine blade was measured by neutron tomography at Paul Scherrer Institut (PSI), Switzerland. The following image is the cross-section of the turbine blade. This is the first application of the de-convolution technique developed by Image Enhancement Technology Ltd on images taken by neutron imaging. The image is provided by Dr. Shu Yan Zhang, Science & Technology Facilities Council, Rutherford Appleton Laboratory, Oxfordshire. We would like to thank EU access programme NMI3 for the financial support to cover the travel expenses for experiment at PSI.
