Question 60/99

Which function should be decreased in order to minimize potential bioeffects?

A. Dynamic Range

B. Output power

C. Depth

D. Frequency

Correct Answer: B

Comprehensive and Detailed Explanation From Exact Extract:
Output power directly affects the intensity of the ultrasound beam transmitted into the patient. Reducing output power lowers the risk of both thermal and mechanical bioeffects.
According to sonography instrumentation reference:
"Output power should be minimized following the ALARA (As Low As Reasonably Achievable) principle to reduce potential bioeffects while still obtaining diagnostic-quality images." Therefore, the correct answer is B: Output power.
