Elemental Contrast X-ray Tomography Using Ross Filter Pairs with a Polychromatic Laboratory Source

Abstract The majority of current laboratory based X-ray sources are polychromatic and are not tuneable. This lack of monochromaticity limits the range of applications for these sources and in particular it reduces the elemental specificity of laboratory based X-ray imaging experiments. Here we prese...
