The feasibility of K-edge imaging using energy-resolved, photon-counting transmission measurements in X-ray computed tomography (CT) has been demonstrated by simulations and experiments. The method is based on probing the discontinuities of the atten

Theoretical considerations predicted the feasibility of K-edge x-ray computed tomography (CT) imaging using energy discriminating detectors with more than two energy bins. This technique enables material-specific imaging in CT, which in combination w

A counting-mode line detector has been evaluated at a synchrotron radiation source in order to assess its performance for imaging applications. The x-ray detector is based on 3 mm thick CdZnTe arrays with 1 mm pixel pitch and multi-threshold counting

X-ray emission spectra from thin targets show significant directional effects that have their origin in the polar dependence of the atomic bremsstrahlung cross section. This fact has led to the idea of enhancing the characteristic lines from an elect

Conventional electron impact X-ray sources invariably use solid state anodes. In this article a novel type of X-ray source is described in which X-rays are produced in a turbulently flowing liquid metal separated from the vacuum region of the X-ray s

The use of energy-dispersive X-ray diffraction (XRD) in security screening applications allows for highest detection and lowest false-alarm rates. So far, only Germanium-detectors have been used in commercially available XRD baggage-scanning systems,
