Figure 3
(a) X-ray projection image of a mouse paw. The dashed line indicates the reconstructed slices as shown in (b) [color bar: linear absorption coefficient (cm−1)] and (c) (color bar: refraction index δ) by the MicroCT and the grating interferometer, respectively. The red arrows in (c) show soft tissues which could be discriminated by the grating interferometer and are absent in (b). Scale bar: 1 mm. |
