Ultrasound is a medical imaging technique that uses high-frequency sound waves to produce images of the inside of the body. It is a non-invasive and safe diagnostic tool commonly used in various medical specialties, including obstetrics, gynecology, cardiology, and musculoskeletal imaging.
Ultrasound machines emit high-frequency sound waves, and when these waves encounter tissues, they bounce back as echoes. The returning echoes are then captured by the ultrasound machine and used to create real-time images of the internal structures.
