ultrasound, also called ultrasonography, in medicine, the use of high-frequency sound (ultrasonic) waves to produce images of structures within the human body. Ultrasonic waves are sound waves that are above the range of sound audible to humans.
What is ultrasound and how is it used science?
Ultrasound imaging uses sound waves to produce pictures of the inside of the body. It helps diagnose the causes of pain, swelling and infection in the body’s internal organs and to examine an unborn child (fetus) in pregnant women. In infants, doctors commonly use ultrasound to evaluate the brain, hips, and spine. .
What is an ultrasound simple definition?
An ultrasound is an imaging test that uses sound waves to create a picture (also known as a sonogram) of organs, tissues, and other structures inside the body. Unlike x-rays, ultrasounds don’t use any radiation.
What is ultrasound and examples?
Overview. Diagnostic ultrasound, also called sonography or diagnostic medical sonography, is an imaging method that uses sound waves to produce images of structures within your body. The images can provide valuable information for diagnosing and directing treatment for a variety of diseases and conditions.

What are the advantages of ultrasound?
Benefits of Ultrasound
- They are generally painless and do not require needles, injections, or incisions.
- Patients aren’t exposed to ionizing radiation, making the procedure safer than diagnostic techniques such as X-rays and CT scans.
- Ultrasound captures images of soft tissues that don’t show up well on X-rays.
Why is a ultrasound done?
An ultrasound allows your doctor to see problems with organs, vessels, and tissues without needing to make an incision. Unlike other imaging techniques, ultrasound uses no radiation. For this reason, it’s the preferred method for viewing a developing fetus during pregnancy.
What type of ultrasound is used for pregnancy?
2D fetal ultrasound
A fetal ultrasound (sonogram) is an imaging technique that uses sound waves to produce images of a fetus in the uterus. Fetal ultrasound images can help your health care provider evaluate your baby’s growth and development and monitor your pregnancy.
Can I eat before an ultrasound?
Adults: Do not eat or drink eight hours before exam. Children: Do not eat or drink four hours before study or skip one meal. Take medications with a small sip of water. If you are diabetic, please take your insulin.

What are the negative effects of ultrasound?
Some of the reported effects include growth restriction, delayed speech, dyslexia, and non-right-handedness associated with ultrasound exposure. Continued research is needed to evaluate the potential adverse effects of ultrasound exposure during pregnancy.
Can ultrasound damage cells?
The ultrasonic intensity at 0.64 W/cm(2) did not cause substantial cell damage, whereas ultrasound exposure at 1 and 2.1 W/cm(2) could induce serious cell death (14.0% and 40.7%, respectively).
Can ultrasound damage internal organs?
An ultrasound uses high-frequency sound waves to produce detailed images of internal organs. Unlike X-rays, ultrasound scanning does not involve radiation, which means that it has no known side effects and is very safe.
Can too many ultrasounds be harmful?
2, 2004 — Having multiple ultrasound examinations during pregnancy is unlikely to cause any lasting harm to the developing fetus, according to a new study that confirms the long-term safety of the commonly used procedure.
How long does an ultrasound take?
