FIG. 1.

X-ray grating interferometer. (a) Setup with a source grating G0, a phase grating G1, and an analyzer absorption grating G2. (b) Through the Talbot effect a linear periodic fringe pattern is created behind G1 in the plane of G2. (c) Intensity modulation detected in a detector pixel when one of the gratings is scanned along . A loss in the amplitude of the oscillation due to the scattering of x rays in the specimen (degradation of the coherent wave front) can be used to extract images with dark-field contrast.

FIG. 2.

X-ray images of a test sample containing two plastic containers filled with a liquid (water, left, A) and a powder (sugar, right, B). (a) Conventional x-ray transmission image. (b) Dark-field image of the same sample. (c) Intensity oscillations observed in detector pixels corresponding to two regions of the sample, extracted from a series of eight images taken at different values of (averaged over 50 pixels). (d) Differential phase-contrast image.

FIG. 3.

Postmortem images obtained for a biological specimen (wing of a blackbird). (a) Conventional transmission image. (b) Dark-field image. (c) Differential phase-contrast image.
