  2. Portable ultrasound - Wikipedia

    en.wikipedia.org/wiki/Portable_ultrasound

    Portable ultrasound. Portable ultrasound is a modality of medical ultrasonography that utilizes small and light devices, compared to the console-style ultrasound machines that preceded them. In most cases these mobile ultrasound systems could be carried by hand and in some cases even operated for a time on battery power alone.

  3. Ultrasonic transducer - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_transducer

    Systems typically use a transducer that generates sound waves in the ultrasonic range, above 20 kHz, by turning electrical energy into sound, then upon receiving the echo turn the sound waves into electrical energy which can be measured and displayed. This technology, as well, can detect approaching objects and track their positions.

  4. Home ultrasound - Wikipedia

    en.wikipedia.org/wiki/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 range of human hearing.

    Pre-hospital ultrasound. Prehospital ultrasound is the specialized application of ultrasound by physicians and other [1] emergency medical services [2] (EMS) to guide immediate care and treatment procedures. Like conventional ultrasound, it is a device that produces cyclic sound pressure to penetrate a medium (different body tissues) and reveal ...

  9. Ultrasound - Wikipedia

    en.wikipedia.org/wiki/Ultrasound

    Ultrasound. 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 several gigahertz.
