Development Background
Currently, image reconstruction of amorphous samples using SPring-8 is
conducted in a three sequential steps: collection of coherent x-ray scattering
data, measurement of scattering distribution with two-dimensional detectors,
and realization of actual image with mathematical phase retrieval.

The California Science Center established the California Scientist of the
Year Award in recognition of the prominent role California plays in the
areas of scientific and technological development. Crystallization and analysis of
membrane protein nano-imaging was extremely difficult with previously
