Why is it important to understand acoustic impedance in ultrasound imaging?.
- A.It determines the speed of ultrasound waves.
- B.It affects the amount of ultrasound energy absorbed.
- C.It influences the quality of the reflected signal.
- D.It has no relevance to ultrasound imaging.
Model answer
What a good answer should say
- It influences the quality of the reflected signal.
Explanation
Why this works
Understanding acoustic impedance is essential in ultrasound imaging because it directly affects the quality of the reflected signals. The differences in acoustic impedance between tissues determine how much of the ultrasound wave is reflected back, which is critical for creating clear images.
