Figure 8: The detailed information about the shear wave signal SNR and the SD values of shear wave speed after adding the excised piece of pork belly, as obtained by the 3 detection pulses at different vibration input voltages.
From: Improved shear wave motion detection using coded excitation for transient elastography

The letters ‘A’, ‘B’ and ‘C’ were marked in the abscissa represent the short pulse, Barker 7, and Barker 13, respectively.
