ARDMS (American Registry for Diagnostic Medical Sonography) Practice Test

Which type of cavitation is the most concerning cause of bioeffects?

1. Absorption

2. Stable

3. Thermal

4. Transient

The correct answer is: Transient

Transient cavitation is the most concerning cause of bioeffects because it is characterized by the violent collapse of bubbles, leading to the generation of shock waves and high temperatures. This can potentially cause damage to surrounding tissues and structures. In contrast, stable cavitation involves stable oscillation of bubbles without violent collapse, absorption cavitation involves absorption of energy by bubbles, and thermal cavitation produces heat without the violent effects of transient cavitation.
