Figure 5
(a) The projection image of a battery electrode sample at an angle when the electrode is parallel to the X-ray beam. (b) The mean normalized value averaged along the row direction as a function of the projection angle index. The mean value drops close to zero in an angle range. (c) A reconstructed slice image with all the projection images over 180° angle range. The stripe lines are due to the low signals in the angle range. (d) The reconstructed slice image with the projection images except that in the angle range in which the mean values are lower than the threshold marked in (b). |
