X-ray computed tomography in life sciences [PDF]
BMC Biology, 2020 AbstractRecent developments within micro-computed tomography (μCT) imaging have combined to extend our capacity to image tissue in three (3D) and four (4D) dimensions at micron and sub-micron spatial resolutions, opening the way for virtual histology, live cell imaging, subcellular imaging and correlative microscopy.

X-ray tomography of the aerospace products [PDF]
MATEC Web of Conferences, 2017 Currently, non-destructive methods are increasingly being used to inspect the critical components in different branches of industry. Special focus is on the usage of high-energy X-ray microtomography used to inspect large objects with high density. This method provides high accuracy and a possibility to measure the internal and external dimensions of ...

X-ray computed tomography [PDF]
Nature Reviews Methods Primers, 2021 X-ray computed tomography (CT) can reveal the internal details of objects in three dimensions non-destructively. In this Primer, we outline the basic principles of CT and describe the ways in which a CT scan can be acquired using X-ray tubes and synchrotron sources, including the different possible contrast modes that can be exploited.

IEEE Transactions on Nuclear Science, 2023 X-ray tomography is a powerful volumetric imaging technique, but detailed three dimensional (3D) imaging requires the acquisition of a large number of individual X-ray images, which is time consuming. For applications where spatial information needs to be collected quickly, for example, when studying dynamic processes, standard X-ray tomography is ...

Quantitative X-ray tomography [PDF]
International Materials Reviews, 2013 AbstractX-ray computer tomography (CT) is fast becoming an accepted tool within the materials science community for the acquisition of 3D images. Here the authors review the current state of the art as CT transforms from a qualitative diagnostic tool to a quantitative one.

X-ray computed tomography [PDF]
Physics Education, 2001 X-ray computed tomography (CT) is a medical imaging technique that produces images of transaxial planes through the human body. When compared with a conventional radiograph, which is an image of many planes superimposed on each other, a CT image exhibits significantly improved contrast although this is at the expense of reduced spatial resolution. A CT

Time-gated x-ray tomography [PDF]
Applied Physics Letters, 1998 Time-gated x-ray tomography with scatter reduction is demonstrated using a laser-produced plasma as an ultrashort-pulse x-ray source in combination with a time-resolving streak-camera detector. Backprojections of a phantom imbedded in 9 cm of water show an effective 50% increase in contrast when scattered x-ray quanta (being delayed in time) are ...

X-ray Compton scattering tomography [PDF]
Inverse Problems in Science and Engineering, 2015 We lay the foundations for a new fast method to reconstruct the electron density in x-ray scanning applications using measurements in the dark field. This approach is applied to a type of machine configuration with fixed energy sensitive (or resolving) detectors, and where the X-ray source is polychromatic.
