What type of wave is primarily used in medical ultrasound imaging, such as prenatal scans?

Explanation

Medical ultrasound imaging uses high-frequency sound waves, above the range audible to humans, which are directed into the body and reflected differently by various tissues and structures. A device converts these returning echoes into a real-time image, commonly used to monitor pregnancies and examine internal organs. Because it uses sound rather than radiation, ultrasound is considered a safe imaging method for repeated use, including during pregnancy.
