DOI: 10.1002/mp.17638
Abstract: K‐edge subtraction (KES) imaging is a dual‐energy imaging technique that enhances contrast by subtracting images taken with x‐rays that are above and below the K‐edge energy of a specified contrast agent. The resulting reconstruction spatially… read more here.

DOI: 10.1016/j.anucene.2020.107970
Abstract: Abstract Computer tomography (CT) is a useful probe to measure two-phase flow parameters. Because of the dynamic characteristic of the two-phase flow, the high temporal CT is required. A compact CT system, consists of seven… read more here.

DOI: 10.1038/s41598-020-72053-z
Abstract: High-intensity X-ray sources are essential diagnostic tools for science, technology and medicine. Such X-ray sources can be produced in laser-plasma accelerators, where electrons emit short-wavelength radiation due to their betatron oscillations in the plasma wake… read more here.
