Ultrasound Waves
Ultrasound waves are sound waves with frequencies higher than the human ear can detect, typically above 20,000 hertz. These waves can travel through various mediums like air, water, and body tissues. In medical imaging, ultrasound is used to create images of internal organs and structures, such as during pregnancy to visualize the developing fetus. The technology works by emitting sound waves that bounce off tissues and return to a detector, creating an image based on the echoes. Ultrasound is valued for being non-invasive, safe, and painless, making it widely used in healthcare.
