Figure 6
Correcting the wax phase reconstruction for X-ray absorption by the aluminium cylinder. (a) For each projection the absorption map is integrated over the pixelated route of the diffracted photons. This is then summed along the length of the incident beam path, thus simulating the TEDDI data collection strategy. The Beer–Lambert law was then applied to each projection to build the absorption-correction sinogram. This is then multiplied with the original data sinogram and then back-projected to finally obtain the corrected image (c). This compares with the uncorrected original (d).
