Stable cavitation is typically characterized by microbubbles that do what?

• A. Oscillate and Absorb Energy Without Violent Collapse
• B. Vanish Immediately
• C. Emit High-Frequency Radiation
• D. Cause Immediate Tissue Destruction

Answer: (A)

Stable cavitation involves microbubbles that oscillate in size in response to the ultrasound field, expanding and contracting without collapsing violently. This oscillation allows the bubbles to absorb energy through viscous dampening and to drive microstreaming in the surrounding fluid, producing mechanical effects on nearby structures without causing a violent collapse. The other descriptions don’t fit this behavior: bubbles don’t vanish immediately, stable cavitation isn’t defined by emission of high-frequency radiation from the bubble, and immediate tissue destruction is associated with inertial (transient) cavitation, not stable cavitation.
