Question 18/99

What would increase with an increase in acoustic power?

A. Frequency

B. Impedance

C. Thermal Index

D. Wavelength

Correct Answer: C

Comprehensive and Detailed Explanation From Exact Extract:
The thermal index (TI) indicates the potential for tissue heating due to ultrasound energy absorption.
Increasing acoustic power increases the amount of energy transmitted into the body, which raises the thermal index.
According to sonography instrumentation reference:
"An increase in acoustic output power results in a corresponding increase in the thermal index, reflecting higher potential for tissue heating." Therefore, the correct answer is C: Thermal Index.
