One reconstructed 16.2 µm-thick slice of mouse kidney specimen. Center bright structure: tissue. Note phase shift modulations. Grey ring: embedding epoxy; black area: water (cell fluid). Bar: phase advance of wave per µm path relative to water. The phase advance is approximately proportional to mass density. From this the spatial mass density distribution of this slice of kidney is found to range between 1.182 g cm−3 and 1.224 g cm−3. E = 71 keV. |
