Question 80/99

What are two types of cavitation in tissue?

A. Heat and transient

B. Thermal and mechanical

C. Stable and transient

D. Thermal and stable

Correct Answer: C

* Heat and Transient: Heat and transient are not classifications of cavitation.
* Thermal and Mechanical: These terms refer to different bioeffects of ultrasound but are not types of cavitation.
* Stable and Transient: These are the two types of cavitation observed in tissues during ultrasound. Stable cavitation involves the oscillation of gas bubbles without collapse, while transient cavitation involves the violent collapse of gas bubbles, which can generate high temperatures and shock waves.
* Thermal and Stable: Thermal effects are a different concept related to tissue heating, not a type of cavitation.
