Final answer:
Ultrasound imaging is a noninvasive diagnostic tool that uses sound waves to create images. It is commonly used in medicine to visualize organs and monitor pregnancies.
Step-by-step explanation:
Ultrasound imaging is a noninvasive diagnostic tool that transforms sound waves into images. It uses the transmission of high-frequency sound waves into the body to generate an echo signal that is converted by a computer into a real-time image of anatomy and physiology. Ultrasound is commonly used in medicine to visualize muscle and soft tissue, making it useful for scanning organs and monitoring pregnancies.
