Which imaging modality uses sound waves to image body structures?

Explanation:
Ultrasound uses sound waves to image body structures. A transducer emits high-frequency sound waves into the body; when these waves encounter different tissues, they bounce back as echoes. The machine analyzes those echoes to create real-time images of organs, blood flow, and other structures. Because it relies on nonionizing sound waves, it doesn’t expose patients to ionizing radiation, making it a common choice for many situations like pregnancy checks, abdominal scans, and heart imaging (echocardiography). In contrast, CT and X-ray depend on ionizing radiation, and MRI uses a strong magnetic field and radiofrequency signals rather than sound waves.
