“…4,5 Because X-ray absorption is sensitive to the atomic number (absorption increases with increasing atomic number), X-ray CT is a useful tool for the detection of heavy elements. 6,7 Conventional dual-energy X-ray CT using monochromatic [8][9][10][11][12] and polychromatic [13][14][15][16][17][18][19][20][21][22] X-ray sources is usually used for the quantification of heavy elements, but in the present study, we investigated the use of single-shot, or single-energy, CT using a polychromatic X-ray source. The advantages of our method are that: (i) single-shot CT reduces the imaging time, prolongs the lifetime of the expensive X-ray tube and detector, and reduces radiation exposure of samples or patients, (ii) polychromatic X-rays can be readily generated by conventional medical CT instruments, and do not require huge facilities, such as particle accelerators.…”

Although the possibilities of X-ray micro-CT are becoming better appreciated in earth science research, the demands on this technique are also approaching certain physical limitations. As such, there remains a lot of research to be done in order to solve all the technical problems that occur when higher demands are put on the technique. In this paper, a review of the principle, the advantages and limitations of X-ray CT itself are presented, together with an overview of some current applications of micro-CT in geosciences. One of the main advantages of this technique is the fact that it is a non-destructive characterization technique which allows 4D monitoring of internal structural changes at resolutions down to a few hundred nanometers. Limitations of this technique are the operator dependency for the 3D image analysis from the reconstructed data, the discretations effects and possible imaging artefacts. Driven by the technological and computational progress, the technique is continuously growing as an analysis tool in geosciences and is becoming one of the standard techniques, as is shown by the large and still increasing number of publications in this research area. It is foreseen that this number will continue to rise, and micro-CT will become an indispensable technique in the field of geosciences.

“…The available X-ray energies allow a wide range of sample sizes and compositions to be examined (Rivers et al 1999). On ultrasmall samples, it is possible to obtain 3-D elemental maps using synchrotron fluorescence microtomography (Rivers et al 2001;Flynn et al 2003;Ikeda et al 2004;Ignatyev et al 2007). For low-density samples (e.g., aerogel), lambda tomography can be used to explore cm-scale volumes at a spatial resolution of 2-3 μm .…”

Abstract-Methods of synchrotron X-ray computed microtomography (XRCMT) are described, which allow nondestructive, high spatial and contrast resolution imaging of the density structures of meteorites and their components in three dimensions. Images of bulk chondrites (to one cubic centimeter in size) reveal compound chondrules, chondrule/matrix volumetric ratios, metal and sulfide distribution, petrofabrics, and 3-D chondrule and calcium-aluminum inclusion (CAI) sizes and shapes. Images of separated chondrules and CAIs reveal void spaces, mineral intergrowth textures, and the true locations of crystal rims and cores, at resolutions to <8 cubic micron/volume element. Images of achondrites reveal mineral fabrics and crystal zoning. Lunar glass spherules can be searched for phenocrysts bearing deeply sourced melt inclusions. A companion DVD and URL contain images for classroom and research use. Numerical techniques for quantification of X-ray computed microtomography (XRCMT) data and its potential applications are discussed. Threedimensional X-ray images of meteorites provide a way to discover components of interest and to precisely slice samples to expose these components with minimal damage and loss of material. Threedimensional studies of petrographic features (size, shape, texture, and modal abundance) of chondrites and their components, as well as other meteorites, have definite advantages over standard 2-D studies using randomly sliced thin sections.
