What type of waves does an ultrasound use to create images of internal body structures?

Ultrasound imaging utilizes sound waves to create images of internal body structures. The process involves the emission of high-frequency sound waves that travel through the body and are reflected back to the ultrasound machine when they encounter different tissues or structures. These returning sound waves are then converted into images, allowing healthcare professionals to visualize organs, tissues, and other internal structures.

In contrast to other types of waves, such as visible light waves or X-rays, which rely on different physical properties and mechanisms, sound waves are non-ionizing and considered safe for various diagnostic applications, including prenatal monitoring and examining soft tissues. The unique advantages of sound waves make ultrasound a widely used imaging modality in medical practice.
