The image sequence shows an 8.3 μm PFC liquid microdroplet undergoing the ADV process initiated by a single pulse of 8 cycles at 7.5 MHz and 3.6 MPa peak negative pressure. The “*” demarcates the presence of the ultrasound pulse in the field of view, and the arrow indicates the direction of the ultrasound wave. Visually, perforation of the bubble occurs after the initial nucleation and after the ultrasound wave has passed at approximately 1 μs after the initial nucleus is seen.
