Spectroscopic MM-OCE in a heterogeneous side-by-side configuration phantom. (a) Geometrical model. (b) MM-OCE response at different excitation frequencies. (c) At lower frequencies (30 Hz) the soft region within the simple gives a higher magnetomotive response while at higher frequencies (315 Hz) the stiff region gives a higher magnetomotive signal.
