In ultrasound imaging, high-frequency sound waves are essential for creating images of structures within the body. These sound waves typically range from 2 to 18 megahertz, which allows for a balance between resolution and penetration. The high frequency is crucial because it enables better resolution, allowing for clearer images of soft tissues and organs.

When these sound waves are emitted from a transducer, they travel through the body and reflect off different tissues and interfaces based on their acoustic properties. This reflection creates echoes, which the ultrasound machine processes to construct images. The ability to capture these high-frequency sound waves is what differentiates ultrasound from other imaging modalities that utilize different types of waves, such as visible light or radio waves.

These unique characteristics make high-frequency sound waves particularly well-suited for applications like prenatal imaging, organ evaluation, and many other diagnostic procedures. This makes high-frequency sound waves the correct choice for this question.
