eSNR and WSR errors for various pulses with two transmission voltages: 5V (a)–(c) and 15V (d)–(f). BB and NB are abbreviations of broadband and narrowband pulses. Note that the abscissas in panels (b), (c), (e), (f) can be converted from WSR (1/s) to WSS (Pa) by multiplying the WSR values by the viscosity of the blood-mimicking fluid, 0.003 Pa-s.
