Fig. 13. Illustration of various diffusion encoding schemes.

Fig. 13.

In each row, an exemplary diffusion weighting gradient waveform was shown on the left (x, y, and z components are shown in blue, green, and red, respectively) and its corresponding b-tensor shape was shown on the right. The diffusion encoding schemes shown here include: a) single diffusion encoding (SDE) (standard Stejskal-Tanner), b) double diffusion encoding (DDE), c) tiple diffusion encoding (TDE), (d-g) q-vector trajectory encoding, d) spherical tensor encoding (STE) or isotropic encoding, e) planar tensor encoding, f) prolate encoding, g) oblate encoding.
