Paper Abstract

Samples a few micrometers in total size offer a challenge to both x-ray and electron tomography. X-ray tomography originated imaging the human body with millimeter resolution, but the resolution has been reduced by over 7 orders of magnitude by the use of synchrotron sources and Fresnel zone plates, leading to an achieved resolution of 20 nm in favorable cases. Further progress may require phase retrieval. Electron tomography originated on very thin samples (perhaps 100 nm thick) but recently samples of over 1 micrometer have been studied with conventional instruments. The study of thicker samples requires understanding tomography in the multiple scattering regime.
