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. Millimeter wave scanner - Wikipedia

   en.wikipedia.org/wiki/Millimeter_wave_scanner

   A millimeter wave scanner is a whole-body imaging device used for detecting objects concealed underneath a person’s clothing using a form of electromagnetic radiation. Typical uses for this technology include detection of items for commercial loss prevention , smuggling , and screening for weapons at government buildings and airport security ...

4. 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.

5. Full body scanner - Wikipedia

   Full body scanner in millimeter wave scanners technique at Cologne Bonn Airport Image from an active millimeter wave body scanner. A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact.

6. Voluson 730 - Wikipedia

   en.wikipedia.org/wiki/Voluson_730

   GE ran ads heavily promoting the Voluson 730's 4D "babyface" capabilities and making it one of the most widely known ultrasound machines in the OB/GYN field. As of October 2011, GE still produces the Voluson 730 though it has created several upgraded successors such as the Voluson E6, Voluson E8, Voluson S6, and S8.

7. 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.

8. Doppler ultrasonography - Wikipedia

   en.wikipedia.org/wiki/Doppler_ultrasonography

   Ultrasound duplex scanning can provide additional information that may guide therapeutic decisions. The location and severity of arterial narrowings and occlusions can be identified. The vascular sonographer can map disease in lower-extremity segments with great accuracy, though duplex scanning is more time-consuming than other lower-extremity ...

9. Phased array ultrasonics - Wikipedia

   en.wikipedia.org/wiki/Phased_array_ultrasonics

   By changing the pulse delays, the computer can scan the beam of ultrasound in a raster pattern across the tissue. Echoes reflected by different density tissue, received by the transducers, build up an image of the underlying structures. Weld examination by phased array. TOP: The phased array probe emits a series of beams to flood the weld with ...
