  2. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    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.

  3. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    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.

  4. Therapeutic ultrasound - Wikipedia

    The bottom probe demonstrates the use of ultrasound for therapeutic benefits, which often utilize high-energy, focused ultrasound beams. In the above applications, the ultrasound passes through human tissue where it is the main source of the observed biological effect (the oscillation of abrasive dental tools at ultrasonic frequencies therefore ...

  5. Ultrasonic transducer - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_transducer

    The transducer may be used in contact with the skin, as in fetal ultrasound imaging, or inserted into a body opening such as the rectum or vagina. Clinicians who perform ultrasound-guided procedures often use a probe positioning system to hold the ultrasonic transducer. [9] Compared to other medical imaging modalities, ultrasound has several ...

    en.wikipedia.org/wiki/Home_ultrasound

    Phonophoresis, also known as sonophoresis, is the use of ultrasound to enhance the delivery of topically applied drugs. Home ultrasound allows the application of topically applied analgesics and anti-inflammatory agents through the therapeutic application of ultrasound. It is widely used in hospitals to deliver drugs through the skin.

    These procedures generally use lower frequencies than medical diagnostic ultrasound (from 0.7 to 2 MHz), but higher the frequency means lower the focusing energy. HIFU treatment is often guided by MRI. Focused ultrasound may be used to dissolve kidney stones by lithotripsy. Ultrasound may be used for cataract treatment by phacoemulsification.
