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.
When we think of ultrasounds, most of us think of pregnancy. But this noninvasive imaging tool is also used to diagnose other health issues for people who get their periods — like misplaced IUD ...
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy. In physics, the term "ultrasound" [1] applies to all acoustic energy with a frequency above the audible range of human hearing. The audible range of sound is 20 hertz – 20 kilohertz. Ultrasound frequency is greater than 20 kilohertz.
Ultrasound in Medicine and Biology is a monthly peer-reviewed medical journal published by Elsevier on behalf of the World Federation for Ultrasound in Medicine and Biology. It covers ultrasound technology in clinical diagnostic , interventional and therapeutic applications, including the physics , engineering , and technology of ultrasound in ...
The University of Texas Health Science Center at Houston (UTHealth Houston) is a public academic health science center in Houston, Texas, United States. It was created in 1972 by The University of Texas System Board of Regents. It is located in the Texas Medical Center, the largest medical center in the world. [3]
Journal of Ultrasound in Medicine is a medical journal that covers aspects of medical ultrasound, mainly its direct application to patient care but also relevant basic science, and biological effects etc.
