Question 33/99

Why is a higher frequency transducer a better choice for imaging superficial structures?

A. Decreased attenuation

B. Increased pulse repetition period

C. Longer spatial pulse length

D. Improved axial resolution

Correct Answer: D

Comprehensive and Detailed Explanation From Exact Extract:
Higher frequency transducers provide better axial resolution due to their shorter wavelengths and spatial pulse lengths. This allows finer detail when imaging superficial structures where penetration is not a concern.
According to sonography instrumentation reference:
"Higher frequencies result in shorter pulse lengths, improving axial resolution and making them ideal for superficial imaging." Therefore, the correct answer is D: Improved axial resolution.
