Results from alignment in [
] and our approach.
(a, b) Images of 3-D volume rendering of the reconstructions from the  (a) and our method (b). (c, e) 2-D cross-sections images of the 3-D reconstruction shown in (a). (d, f) Images of corresponding 2-D cross-sections of the 3-D reconstruction shown in (b). (g, h) Plots of the path of the projected global center of mass along the y-axis for the two alignment methods. (i, j) Plots of the path of a center of mass along a single cross-section of the projections for the two alignment methods.
