  2. Therapeutic ultrasound - Wikipedia

    en.wikipedia.org/wiki/Therapeutic_ultrasound

    Ultrasound is applied using a transducer or applicator that is in direct contact with the patient's skin. Gel is used on all surfaces of the head to reduce friction and assist transmission of the ultrasonic waves. Therapeutic ultrasound in physical therapy is alternating compression and rarefaction of sound waves with a frequency of 0.7 to 3.3 MHz.

    en.wikipedia.org/wiki/Home_ultrasound

    Home ultrasound. Home ultrasound is the provision of therapeutic ultrasound via the use of a portable or home ultrasound machine. 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 ...

    en.wikipedia.org/.../Low-intensity_pulsed_ultrasound

    Low-intensity pulsed ultrasound ( LIPUS) is a technology that can be used for therapeutic purposes. It exploits low intensity and pulsed mechanical waves in order to induce regenerative and anti-inflammatory effects on biological tissues, such as bone, [1] cartilage, and tendon. [2] Even if the real mechanism underlying its effectiveness has ...

    en.wikipedia.org/wiki/Focused_ultrasound

    High-intensity focused ultrasound ( HIFU) is a non-invasive therapeutic technique [1] that uses non-ionizing ultrasonic waves to heat or ablate tissue. HIFU can be used to increase the flow of blood or lymph or to destroy tissue, such as tumors, via thermal and mechanical mechanisms. Given the prevalence and relatively low cost of ultrasound ...

  6. Medical ultrasound - Wikipedia

    en.wikipedia.org/wiki/Medical_ultrasound

    The usage of ultrasound to produce visual images for medicine is called medical ultrasonography or simply sonography, or echography. The practice of examining pregnant women using ultrasound is called obstetric ultrasonography, and was an early development of clinical ultrasonography. The machine used is called an ultrasound machine, a ...

  7. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    An ultrasonic examination. 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. Ultrasonic devices operate with frequencies from 20 kHz up to ...
