Over the four days we had attendees representing academia, research centres, start-up companies and large multinational corporations joining us. Once again, the training course (Day 1-2) was oversubscribed and the forum (Day 3-4) had the largest number of ‘in-person’ attendees since the event launched in 2018. For the second time, the event was hosted by the IOP at their headquarters in London.
Keynote Speakers
Regius Professor Philip Withers, University of Manchester & the Henry Royce Institute for Advanced Materials
CT image-based modelling of composite materials’ failure
Philip Withers is the first Regius Professor of Materials at the University of Manchester and Chief Scientist of the Henry Royce Institute for Advanced Materials initiated. The Royce brings together the universities of Manchester, Leeds, Sheffield, Oxford, Cambridge, Cranfield, Strathclyde and Imperial College, NNL and UKAEA to support the accelerated design of new materials and a better understanding of existing ones. He has pioneered the use of X-ray CT and electron microscopy to undertake correlative multiscale, multimodal and time-lapse characterisation to follow the behaviour of engineering materials often in 3D and exposed to demanding environments in operando. In 2008 he set up the Henry Moseley X-ray Imaging Facility, one of the most extensive suites of X-ray Imaging facilities in the world with a special focus on in situ time lapse 3D X-ray imaging and now part of a National Research Facility for Lab. X-ray CT. In 2014, the Facility was awarded the Queen’s Anniversary Prize.
Dr Jean Michel Létang, CREATIS, INSA, Université de Lyon
Monte Carlo simulations for X-ray imaging: applications in metal fatigue crack characterization
Jean Michel Létang graduated in 1990 from INSA Lyon (electrical engineering dpt) in France. He received his PhD degree in Signal and Image processing from INP Grenoble in 1993. He held several post-doctorate positions in computer vision at INRS-telecom in Montréal (Canada) and at INRIA Grenoble. In 1996 he joined the medical imaging department of Philips Research Laboratories in Paris as a research engineer. Since 1999, he has been an associate professor in nondestructive testing at INSA (mechanical engineering dpt) and conducted his research at the CREATIS medical imaging laboratory. His main research interest in on Monte Carlo simulations for particle transport, and in particular the development of fixed-force detection and variance reduction techniques based the track-length estimator for both imaging and dosimetry. He has been collaborating since 2005 with nuclear physics and instrumentation laboratories for prompt-gamma control in particle therapy. He is also closely involved in reconstruction techniques for tomography, both photons and protons, and in the development of wave modeling for x-ray phase contrast simulations. He has co-supervised more than 20 PhD thesis and co-authored more than 100 papers in international peer-reviewed scientific journals.
