Dec 12, 2019 · What is an ultrasound? An ultrasound scan 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. The...
Ultrasound is sound with frequencies greater than 20 kilohertz. [1] This frequency is the approximate upper audible limit of human hearing in healthy young adults. The physical principles of acoustic waves apply to any frequency range, including ultrasound.
Ultrasound (also called sonography or ultrasonography) is a noninvasive imaging test. An ultrasound picture is called a sonogram. Ultrasound uses high-frequency sound waves to create real-time pictures or video of internal organs or other soft tissues, such as blood vessels.
May 3, 2024 · Ultrasound, also called sonography, shows the structures inside the body. The images can help guide diagnosis and treatment for many diseases and conditions. Most ultrasounds are done using a device outside the body.
Diagnostic ultrasound is a non-invasive diagnostic technique used to image inside the body. Ultrasound probes, called transducers, produce sound waves that have frequencies above the threshold of human hearing (above 20KHz), but most transducers in current use operate at much higher frequencies (in the megahertz (MHz) range).
Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound.
Jul 19, 2023 · Ultrasound is a type of imaging technology that is used to diagnose, monitor, and treat a variety of medical conditions. It uses sound waves to generate live images (sonograms) of your...
Sep 20, 2023 · Ultrasound, also called sonography, uses sound waves to develop ultrasound images of what's going on inside the body. An instrument called a transducer emits high-frequency sound, inaudible to...
Listen. Key facts. An ultrasound scan creates a real-time picture of the inside of the body using sound waves. Ultrasounds are generally painless and non-invasive. That are used for to screen for or diagnose many conditions or to help with treatment.
Abdominal Ultrasound. An abdominal ultrasound uses high-frequency sound waves to see structures inside your belly. This test checks the health of your abdominal organs — like your liver, gallbladder and kidneys — and the blood vessels that lead to them.
