Ultrasound is a medical test that uses high-frequency sound waves to capture live images from the inside of your body. It’s also known as sonography. An ultrasound allows your doctor to see problems with organs, vessels, and tissues without needing to make an incision. This type of imaging is particularly useful for examining the fetus during pregnancy.
How does ultrasound work?
Ultrasound uses sound waves to show pictures of what’s going on inside the body. An instrument called a transducer sends out high-frequency sound that humans can’t hear, and then records the echoes as the sound waves bounce back to determine the size, shape, and consistency of soft tissues and organs. The sound waves travel through your skin and other body tissues to the organ or tissue that is being studied. Most ultrasound exams are done using a transducer on the surface of the skin.
What are some other uses of ultrasound?
What are the risks of ultrasound?
Diagnostic ultrasound and/or sonography is considered a safe, noninvasive procedure by most every medical community, in part, because it uses low-power sound waves. There are several studies showing that low-level exposure to ultrasound is not harmful, but higher levels may be harmful or even lethal.
To write a content on this is not easy because there will be a lot of information. So tried to inform a Non-tech person in a very superficial way. Thank you.
