Which of the following statements about ultrasound imaging is accurate?

Ultrasound imaging is based on the use of high-frequency sound waves, which are transmitted into the body and reflected back to create images. This technique is non-invasive and allows for real-time imaging of various structures within the body. The sound waves are above the audible range for humans, typically between 1 MHz and 20 MHz, which is essential for generating detailed images of soft tissues and organ structures.

The ability to use these high-frequency sound waves is what enables ultrasound to visualize both superficial and deeper tissues effectively. The reflections from tissues of varying densities contribute to the formation of cross-sectional images and other views, which are crucial for diagnostic purposes. This characteristic of utilizing sound waves differentiates ultrasound from imaging modalities that require ionizing radiation or other imaging principles.

In summary, ultrasound's reliance on high-frequency sound waves for imaging is fundamental to its diagnostic capabilities and advantages, making this statement accurate.
