Combined X-ray fluorescence and absorption computed tomography using a synchrotron beam

摘要: X-ray computed tomography (CT) and fluorescence (FXCT) using synchrotron sources are both useful tools in biomedical imaging research. Synchrotron CT (SRCT) its various forms is considered an important technique for since the phase coherence of SR beams can be exploited to obtain images with high contrast resolution. Using a as source FXCT ensures signal that optimally detectable by exploiting beam monochromaticity polarisation. The ability combine these techniques so SRCT collected simultaneously, would bring distinct benefits certain experiments. Simultaneous image acquisition alleviate some registration difficulties which comes from collecting separate data, it provide increased information about sample: functional FXCT, morphological SRCT. A method presented generating simultaneous images. Proof principle modelling has been used show possible recover point-like apparatus suitably modulating illuminating planar beam. projection successfully reconstruction removing static modulation sinogram normal flat dark field processing.
