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. However, some involve placing a small device inside the body.
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.
What is an ultrasound? An ultrasound scan is a medical test that uses high-frequency sound waves to capture live images inside your 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. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g. distances and velocities) or to generate an informative audible sound.
An ultrasound is an imaging test that uses sound waves to make pictures of organs, tissues, and other structures inside your body. It allows your health care provider to see into your body without surgery. Ultrasound is also called ultrasonography or sonography. Ultrasound images may be called sonograms.
Jan 14, 2019 · This article provides a beginners guide to ultrasound (POCUS), including how ultrasound works and how ultrasound can be used in clinical practice. The article also covers ultrasound-guided venous access and FAST scanning in the context of trauma.
Jun 14, 2022 · An ultrasound is a noninvasive, painless imaging exam. It makes pictures of organs and structures inside the body using sound waves. This is the diagnostic or anatomical ultrasound. It lets doctors view internal tissues that may be the source of disease. Doctors use it to find the cause of symptoms, such as pain.
