Figure 1.

The gradient waveforms (upper left) adopted in this work to achieve an isotropic sensitivity to diffusion. The resulting path through q-space is shown in the lower left and the build-up of sensitivity to the diffusion tensor (i.e., the B-tensor) is shown on the right (on- and off-diagonal elements are plotted separately using the colour coding shown in the tensor in the upper right). The gradient waveforms have been designed to obtain a B-tensor that is a multiple of the unit tensor (right) and are corrected for the bias that concomitant gradients might cause in such asymmetric gradient waveforms (Szczepankiewicz et al., 2019b).
