Numerical simulations. Fig.a. Original tensors used to simulate the DW signal. Fig.b–d: Tensors estimated resp. from a single LR acquisition, from the mean of the LR acquisitions and from the SRR. Fig.e–h: Corresponding tensor fractional anisotropy. It shows the tensor directions to be well estimated from the mean (Fig.c). However, the SRR provides a much more accurate reconstruction of the complete tensor (see the better FA uniformity in Fig.h).
