Figure 2

A sketch of the motion encoding scheme in SDP-MRE relative to the multifrequency mechanical excitation signal is shown during one TR. The trigger is shifted 16 times over a 1 ms interval in order to vary the starting time s of the MEG relative to the mechanical vibration for temporal resolution. The start of the MEG was delayed 1 ms – 2 ms (depending on the respective time step) relative to the start of the mechanical excitation signal to ensure penetration of the shear wave into the sample center before motion encoding.
