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.

X-ray induced acoustic computed tomography [PDF]
Photoacoustics, 2020 X-ray imaging has proved invaluable in medical diagnoses and non-destructive testing (NDT) in the past century. However, there remain two major limitations: radiation harm and inaccessibility to the sample.

In situ 3D characterization of fatigue cracks displacement fields [PDF]
Fracture and Structural Integrity, 2013 The three dimensional growth of fatigue cracks in samples of nodular graphite cast iron is characterized using laboratory X-ray computed tomography. The cracks grow from laser machined artificial defects, their development is monitored in situ using ...

Multi-Mounted X-Ray Computed Tomography. [PDF]
PLoS ONE, 2016 Most existing X-ray computed tomography (CT) techniques work in single-mounted mode and need to scan the inspected objects one by one. It is time-consuming and not acceptable for the inspection in a large scale.
