2. Portable ultrasound - Wikipedia

   en.wikipedia.org/wiki/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. Doppler ultrasonography - Wikipedia

   en.wikipedia.org/wiki/Doppler_ultrasonography

   All modern ultrasound scanners use pulsed Doppler to measure velocity. Pulsed wave instruments transmit and receive series of pulses. The frequency shift of each pulse is ignored, however the relative phase changes of the pulses are used to obtain the frequency shift (since frequency is the rate of change of phase).

4. Terason - Wikipedia

   en.wikipedia.org/wiki/Terason

   Terason was the first to patent color portable ultrasound [1] and is a market leader in ultrasound-guided venous intervention. [2] Terason produces portable ultrasound products and technologies and has provided ultrasound systems to clinicians, hospitals, outpatient centers, and OEM partners since 2000.

5. Sonicaid - Wikipedia

   en.wikipedia.org/wiki/Sonicaid

   Sonicaid developed a range of fetal monitors, notably the portable Doppler ultrasound products D102, D104 ("Pocket Sonicaid", winner of a Design Council Award for medical equipment in 1976 [2]), D205 [3] [4] and D206 which provided audible output of fetal heart sounds. The original design was due to Frederick (Doug) Fielder who was Sonicaid's ...

6. 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.

7. Ultrasonic flow meter - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_flow_meter

   Schematic view of a flow sensor. An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and ...
