SPI ULTRASOUND PHYSICS REVIEW

True or False? Focused sound beams are considered less likely to create bioeffects because the beams will strike fewer gas bubbles that could potentially cavitate. Correct Answer: True. Small gas bubbles, or gaseous nuclei in tissues, serve as sites of cavitation. Certain studies of bioeffects are performed in vitro. What is the meaning of in vitro? A) visible in a living organism B) observations based on experiments C) discernible in a test tube D) perceptible in a living human being Co...
