Which term means the imaging modality that uses sound waves to visualize internal structures?

Explanation:
Ultrasonography uses sound waves to visualize internal structures. It works by emitting high-frequency pulses from a handheld transducer into the body; the echoes that return from tissue interfaces are processed to create real-time images. Because it relies on sound waves rather than ionizing radiation, it’s widely used for soft tissues, obstetrics, and guiding procedures. Other imaging methods use X-rays or radioactive tracers, not sound waves, which is why they aren’t the modality described here.
