Ultrasound, also known as Sonography, is a safe, painless, and non-invasive imaging technique that uses high-frequency sound waves to create real-time images of the inside of the body. It is one of the most widely used diagnostic tools in modern medicine because it is radiation-free, quick, and effective.
Ultrasound is commonly used for:
During an ultrasound scan, a small device called a transducer is placed on the skin after applying a special gel. This transducer emits high-frequency sound waves that travel through the body. These sound waves bounce back when they hit organs, tissues, or fluids, and the returning echoes are converted into images on a monitor.
