K-Optimal Gradient Encoding Scheme for Fourth-Order Tensor-Based Diffusion Profile Imaging

Figure 2

Results of rotational variance test for (): mean signal deviation (vertical axis) is computed using Algorithm 1 given in the Appendix. The horizontal axis denotes 343 rotation matrices described in Section 4.2. Signal deviation of the -optimal GES is consistently lower than that of the DISCOBALL scheme [26].
