Articular cartilage depicted at optimized angular position of Laue angular analyzer by X-ray dark-field imaging.

Using 36.0 keV X-ray from synchrotron radiation, we examined the optimized angular position of Laue analyzer for depicting articular cartilage of an intact human finger by X-ray dark-field imaging. The surface of articular cartilage was depicted clearly by adopting the offset angle of 0.04 arcsec to lower angular side to the analyzer whilst the contour of articular cartilage was delineated clearly at the other angular positions of the analyzer within the width of the rocking curve.
