Spectrogram of time-dependent passive cavitation detector signals and plots of time-dependent acoustic emissions for trial 5. (A) Spectrogram of time-dependent passive cavitation detector signals (in dB-scaled SNR) for trial 5 with 20,570 W/cm2 SPTP focal intensity. (B) Plots of time-dependent acoustic emissions (dB-scaled SNR) and flow-meter output current for trial 5. No vessel rupture occurred in this trial.
