摘要: We demonstrate computerized tomography (CT) reconstructions from absorption, phase and dark-field signals obtained scans acquired when the x-ray probe light is modulated with speckle. Two different interlaced schemes are proposed to reduce number of sample exposures. First, already demonstrated speckle-vector tracking (XSVT) concept for projection imaging allows three signal CT multiple images per projection. Second, a modified XSVT approach shown provide absorption reconstructions, this time single image angular Reconstructions data at synchrotron facility emphasize potential approaches complex samples.
