Ultrasonography, also known as ultrasound imaging, is a diagnostic imaging technique that uses high-frequency sound waves to produce images of the inside of the body. It is widely used in medical practice due to its safety, non-invasive nature, and ability to provide real-time imaging.

How It Works

1. Sound Waves: A transducer (a small handheld device) emits high-frequency sound waves into the body.
2. Echoes: These sound waves bounce off tissues, organs, and other structures, creating echoes.
3. Image Formation: The echoes are captured by the transducer and converted into images by a computer.
