Recently, more attentions are paid on liquid security screening, and XRD proves to have great capability to distinguish liquid contrabands from daily supplies. In this study, we set up an Energy Dispersive X-ray Diffraction (EDXRD) test bed facility, and conduct many tests on dozens of liquid samples. Results show the great potential of the XRD for liquid contrabands classification, and XRD's advantages...
Dual energy CT (DECT) can target to reconstruct the spatial distribution of the electron density and the atomic number or the mass density of materials. In the literature, there are two kinds of processing methods for DECT to incorporate analytically the basis function decomposition. Taking decomposition in projection-domain before spatial reconstruction is referred as pre-processing method, while...
Hard X-ray grating-based imaging has the most potential in clinical applications because it works well with conventional X-ray tubes and provides multiple information (absorption, refraction and scattering) simultaneously. How-ever, grating-based imaging adopts a series of images to retrieve multiple information, which significantly increases the exposure time and doses compared with conventional...
