X-ray phase contrast imaging has been translated from the synchrotron to the laboratory using different techniques such as free space propagation, grating interferometry, Zernike phase contrast and edge illumination. The emergence of new high performance laboratory sources is a significant boost to the field.
This workshop aims to bring together the community working on the development of the techniques as well as the end users to discuss progress, current challenges and future directions.
Scientific Organisers
Silvia Cipiccia
Silvia is a lecturer in Advanced X-ray Imaging at the Department of Medical Physics and Biomedical Engineering at the University College London. Silvia is an expert in x-ray imaging, especially on coherent diffraction imaging and on novel schemes of compact light sources, namely laser-plasma driven radiation sources. Her work aims to pushing the boundaries of x-ray quantitative phase imaging, in particular x-ray ptychography, in terms of information content and acquisition modalities. Her recent work focuses on translating x-ray imaging techniques born at synchrotron facilities to compact light sources, from standard x-ray tubes to more innovative technologies such as inverse-Compton and laser-plasma sources; in all these cases, she adapts the imaging techniques to the unique properties of the sources. As part of this, in her recent works, Silvia pioneered the lab translation of far-field x-ray ptychography and has proven simultaneous phase and dark field imaging are possible at the femtosecond using laser-driven x-ray sources.
Charlie Wood
Charlie is the X-ray facility manager within the Future Technology Centre at the University of Portsmouth. His research focuses on lab-based X-ray technique and technology development. As the founder of the Correlative Multimodal Microscopy (CoMic) Network he explores multidimensional workflows that span several modalities at different length scales. Charlie’s background is in pure mathematics and physics. He completed his PhD in nuclear fusion (liquid metal magnetohydrodynamics) at Queen Mary University of London. It wasn’t until his first postdoctoral position at the University of Southampton that Charlie began working with X-rays. Moving about different postdoctoral positions, Charlie collected knowledge on various characterisation techniques involving lasers and electrons, before moving to Imperial College to research the link between material microstructure and macroscopic performance for batteries and fuel cell electrodes. During this time Charlie managed an X-ray lab within the Royal School of Mines, and it was here that he started to explore correlative methods using X-ray imaging and volume electron microscopy (vEM). Charlie has been the co-chair of the Royal Microscopical Society X-ray group since Jan 2021, and has recently started the vEM CoMic X-ray Group, of which he is chair.
Marco Endrizzi
Marco Endrizzi is Professor of Experimental Physics at the Department of Medical Physics and Biomedical Engineering, University College London. He is part of the Advanced X-ray Imaging group, where X-ray phase-contrast imaging (XPCI) techniques have been pioneered and developed for nearly two decades. His contributions include a method for X-ray dark-field imaging under incoherent illumination, hence suitable for laboratory settings as it is compatible with standard X-ray tubes. Marco is co-Director of the National Research Facility for lab-based X-ray Computed Tomography (NXCT, https://nxct.ac.uk/), which makes the first lab-XPCI systems openly available to industry and the research community, and leads the X-ray Microscopy and Tomography lab at the The Francis Crick Institute (https://www.crick.ac.uk/research/labs/marco-endrizzi).
