Reconstruction quality for a simulated porous material data set. a Original phantom, b reconstruction of the deformed data set by a standard SIRT method, c reconstruction by an NCT-based SIRT method with self-consistently estimated DVF. An axial tomographic cut through the first-principal component of the reconstructed 4D-DVF (d) differs from the model DVF (e) only by an RMS of 0.8 pixel. The corresponding weights of the principal components, i.e., their time evolution, in the five interpolation nodes are shown in (f)
