Figure 5: The detailed information about the shear wave signal SNR and the SD values of shear wave speed obtained by the short pulse, Barker 7, and Barker 13 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.
