Computed tomography using synchrotron radiation

A new quantification procedure for elemental mapping by X-ray (absorption) microscopy

“…In the longer term, these concepts will also be applied to X-ray microtomography (following the way initiated by Thompson et al [37] and Hirano et al [38]) and to dynamic studies in X-ray microscopy [39]. At last, one may observe that some of the concepts developed here may also be adapted to conventional radiography and tomography.…”

A review of non-invasive imaging methods and applications in contaminant hydrogeology research

“…The basic concept behind synchrotron X-ray microtomography (SMT) is the same as for X-ray computed tomography. It is the availability of high-energy (synchrotron) sources and improvements in data collection and processing that has supported the development of SMT (e.g., Thompson et al, 1984; Bonse et al, 1986; Flannery et al, 1987a, b; Spanne and Rivers, 1987; Tjahjadi and Bowen, 1987; Kinney et al, 1988). The method is based on mapping the spatially-distributed differential absorption of an X-ray beam as it passes through the sample.…”

High energy high resolution monochromatic x-ray computed tomography using the Photon Factory vertical wiggler beamline

“…3 Recently it has been used to evaluate fine structures of materials with spatial resolution up to 10 pm.67 Improvement in resolution was achieved by magnifying projections of object cross sections using asymmetric Bragg reflection from a Ge or Si crystal or by using high resolution detectors. However, suitable objects are restricted to light metals or composites such as Al because of the low transmitted intensity or low penetration.…”
