The 5th International Conference on X-ray and Neutron Phase Imaging with Gratings (XNPIG) will be held at Sendai International Center, Sendai, Japan on 20-24 October, 2019. This meeting will be organized by Japan Science and Technology Agency and Institute of Multidisciplinary Research for Advanced Materials, Tohoku University.


Since the early 1990s X-ray phase imaging methods that utilize wave nature of X-rays have been extensively developed to overcome the limitation of conventional X-ray imaging based on absorption. Above all, grating-based phase-imaging methods appeared in the 2000s have attracted increasing attention because laboratory-based X-ray sources are available and therefore practical and extensive applications of X-ray phase imaging are expected. The concept of phase imaging is also feasible for neutron imaging, and neutron phase imaging has been developed in parallel.
Since 2012, a series of XNPIG meetings are held for the scientists in this specific field including from industry to discuss and exchange the state-of-art technology.
The topics of XNPIG2019 in terms of phase imaging with gratings and/or relevant devices are:

Methods and instrumentation
Grating fabrications
Detectors and radiation sources
Signal retrieval and algorithmics
Materials science and industrial applications
Life science and biomedical/clinical applications
