Noninvasive 3D Structural Analysis of Arthropod by Synchrotron X-Ray Phase Contrast Tomography

Figure 3

Representative tomographic slices reconstructed from projections with and without phase retrieval. In the directly reconstructed tomographic slice (a), the interfaces of different tissues are distinguishable. However, accurate determination of different organs with the distribution of density is difficult. In the slice reconstructed with projections after phase retrieval (b), the precise interior structures of earthworm with characteristic mass density can be easily identified. The zoomed-in region (d) shows less noise and better image quality than (c) (scale bars in (a) and (b), 1 mm; in (c) and (d), 0.5 mm).
