Desktop X-ray microscopy and microtomography
Journal of Microscopy, 1998Recent developments in X-ray microtomography have made it possible to miniaturize a CT scanner into a versatile and cost-effective desktop system that fits into any laboratory environment. The possibilities of the technique are demonstrated for a range of applications. It is also shown how an existing scanning electron microscope with an X-ray detector

Development of Quantitative X-Ray Microtomography
MRS Proceedings, 1990 ABSTRACTWe have developed several x-ray microtomography systems which function as quantitative three dimensional x-ray microscopes. In this paper we describe the evolutionary path followed from making the first high resolution experimental microscopes to later generations which can be routinely used for investigating materials.

SUMMARYA microscope system based on the principles of computerized axial tomography is described for determining the distribution of the X‐ray absorption coefficient in a slice from a solid object without cutting sections. An application is given to determining the distribution at a resolution of about 15 μm through a shell of about 0·5 mm diameter.

Proceedings, annual meeting, Electron Microscopy Society of America, 1988
We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As

X-ray microtomography of bones and teeth
Physiological Measurement, 1996X-ray microtomography is a miniaturized version of computerized axial tomography with a resolution of the order of micrometres. In the biomedical field it is particularly useful in the study of hard tissue because of its ability to accurately measure the linear attenuation coefficient.

Three-Dimensional X-Ray Microtomography
Science, 1987The new technique of x-ray microtomography nondestructively generates three-dimensional maps of the x-ray attenuation coefficient inside small samples with approximately 1 percent accuracy and with resolution approaching 1 micrometer. Spatially resolved elemental maps can be produced with synchrotron x-ray sources by scanning samples at energies just ...

X-ray diffraction microtomography
Measurement Science and Technology, 1993A table-top system has been developed for tomographic imaging of the internal structure of objects of low mass density at sub-millimetre resolution. Images are based on the X-ray diffraction properties of constituent materials, and are reconstructed from tomographic data using summation-filtered back-projection.

Applications of Synchrotron X-Ray Microtomography to Mesoscale Materials [PDF]
Advances in Complex Systems, 2001 We discuss the application of synchrotron X-ray microtomography (XMT) to granular matter, foams, crumpled membranes, and paper. XMT provides rapid, high-resolution, fully three-dimensional characterization of each of these classes of material. In some cases, subsequent three-dimensional image processing allows the virtual reconstruction of the ...

X-ray microtomography of materials
International Materials Reviews, 1999X-ray microtomography allows imaging of the interior microstructure of materials non- destructively and with spatial resolution which can approach that of optical microscopy (typically, no better than 1 μm in samples whose cross-sectional diameter is on the order of 1 mm, and 10 &µm for 10 mm specimens).

Synchrotron X-Ray Microtomography
1988We present results obtained with a new form of 3-D microscopy. The technique is based on tomographic methods and we refer to it as 3-D Microtomography. When used with a tunable X-ray source, it is a powerful diagnostic and research tool for a wide variety of materials studies problems.
