Figure 1.

Dynamics of a typical lithotripsy bubble as characterized by (a) the radial dynamics and (b) the gaseous content inside the bubble (note that the plot displays the molar content normalized by the bubble’s initial state). Plotted curves were generated using a model comparable to that from Matula et al. (Ref. 15). The radial dynamics are characterized by prolonged bubble growth after passage of the incident shock wave, followed by an unforced inertial collapse and subsequent rebounds. Consideration of the bubble’s contents demonstrates that the quantity of vapor can easily exceed that of noncondensable gases.
