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.
Sonalleve HIFU. Sonalleve MR-HIFU is a medical system developed by Philips Healthcare for the treatment of uterine fibroids without surgery. The system uses non-invasive high-intensity focused ultrasound (HIFU) guided by magnetic resonance (MR), hence the acronym MR-HIFU.
Gerard Philips (1858–1942), founder. The Philips Company was founded in 1891, by Dutch entrepreneur Gerard Philips and his father Frederik Philips. Frederik, a banker based in Zaltbommel, financed the purchase and setup of an empty factory building in Eindhoven, where the company started the production of carbon-filament lamps and other electro-technical products in 1892.
Therefore, most conventional ultrasound methods require the use of some type of acoustic coupling medium in order to efficiently transmit the energy from the sensor to the test material. Couplant materials can range from gels or jets of water to direct solder bonds. However, in non-contact ultrasound, ambient air is the only acoustic coupling ...
There’s a limit to how long a movie can mess with viewers’ minds, and “Ultrasound” eventually crosses that threshold. A thriller whose discomforting early going provides few clues to the ...
Video 2000 (also known as V2000, with the tape standard Video Compact Cassette, or VCC) is a consumer videocassette system and analogue recording standard developed by Philips and Grundig to compete with JVC's VHS and Sony's Betamax video technologies. [1] It was designed for the PAL color television standard, but some models additionally ...
Aimed at schools, [15] it was unsuccessful and production ended in 1986. [16] 300 000 units were sold in 1984 according to an internal Philips report, with 500 000 predicted for 1985. [13]
Picosecond ultrasonics is a type of ultrasonics that uses ultra-high frequency ultrasound generated by ultrashort light pulses. It is a non-destructive technique in which picosecond acoustic pulses penetrate into thin films or nanostructures to reveal internal features such as film thickness as well as cracks, delaminations and voids.
