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

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.
