(a) Tomography reconstruction by filtered back projection of the Gaussian area of the fitted cobalt Kα peak. (b) The reconstruction of the same data processed after absorption correction of the sinogram. Insets of (a) and (b) show a slight sharpening of the features in the absorption corrected image. The scale bar represents 20 µm. (c) Histograms of both corrected and uncorrected data showing a slight improvement in contrast. |
