Document Content and Description Below

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 bub... bles, 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 Correct Answer: C. Which component of an u/s system exposes a patient to greatest risk? A) the CRT B) the electric cord C) the pulser D) the transducer Correct Answer: D. T or F? The AIUM suggests that in vitro research confirming bioeffects is valuable and valid. their results are significant and should be directly applied to the clinical arena. Correct Answer: F. It is difficult to assess their direct clinical significance. Which of the following statements regarding cavitation is true? A) it has never been observed in any biologic media B) stable cavitation relates to oscillating bubbles while transient relates to bursting bubbles C) it is a nonlethal bioeffect produced in animal experiments D) waves with peak pressures <100MPa can never induce cavitation Correct Answer: B What is epidemiology the study of? A) large groups B) the prevalence of disease [Show More]
