Transmission electron microtomography in soft materials
Microscopy, 2012This review summarizes the recent advances in three-dimensional (3D) imaging techniques and their application to polymer nanostructures, for example, microphase-separated structures of block copolymers. We place particular emphasis on the method of transmission electron microtomography (electron tomography for short; hereafter abbreviated as ET).

Ethanol bone evaluation using 3D microtomography
Micron, 2008The study of trabecular structures is important for understanding the mechanism of alcohol related to bone changes. Alcohol consumption can compromise the body mineral composition, affecting the bone metabolism and compromising the skeleton. The effects of the ethanol treatment on the internal microarchitecture of bone samples through 3D microcomputed ...

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.

EPR imaging in biological applications: Towards microtomography
Magnetic Resonance in Chemistry, 1995AbstractEPR imaging and microtomography promises to be a powerful tool for the EPR spectroscopist, but the expansion of this technique was hindered by the lack of commercial apparatus. A simple modification of an existing commercial system that can reach a resolution of the order of 75 μm with a gradient of 150 mT m−1 is described.

Microtomography with ionising radiations
Applied Radiation and Isotopes, 1995Abstract The physical requirements for tomographic imaging with x-ray photons and energetic ions beams are reviewed and some illustrative applications are briefly described. The number of x-ray photons needed to produce tomographic images of a given quality in terms of spatial and density resolution is shown to be independent of object size ...

Brute force absorption contrast microtomography
SPIE Proceedings, 2014In laboratory X-ray microtomography (XMT) systems, the signal-to-noise ratio (SNR) is typically determined by the X-ray exposure due to the low flux associated with microfocus X-ray tubes. As the exposure time is increased, the SNR improves up to a point where other sources of variability dominate, such as differences in the sensitivities of adjacent X-

Synchrotron microtomography of supported catalysts
Review of Scientific Instruments, 1989Synchrotron microtomography is a new technique which is capable of elemental, chemical, and structure sensitive imaging in three dimensions at resolutions better than 15 μm. This paper describes the first application of this new technique to the investigation of the morphology and elemental distribution of a supported catalyst.

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 t...
