Figure 6

Inertial cavitation dose as a function of time with and without a vaporization pulse. The inertial cavitation dose, averaged between 1.7 and 2.1 MHz and normalized by the initial cavitation dose measured at the onset of sonication with PSNE, is plotted for the tests shown in Figure 5. Note that the time is plotted on a logarithmic scale. The peak temperature rise in Figure 5 corresponded to the time when the inertial cavitation dose was at its peak (within 1 s of vaporization).
