Ultrasound (US) is a relatively cheap, widely available imaging technology that uses sound waves to create images. No ionizing radiation is used. This chapter will focus primarily on fundamental concepts pertaining to B-mode (brightness mode) or 2D mode ultrasound, which is used in anatomic ...
Air is the enemy of ultrasound. Ultrasound waves tend to reflect strongly wherever air meets biological tissue. If there is even a small bubble between the probe and the patients skin, the ultrasound waves will be reflected away instead of penetrating the skin. Without the waves going into the...
Ultrasonic sensors work best when positioned in front of materials that readily reflect ultrasonic waves, such as metal, plastic and glass. This enables the sensor to give an accurate reading at a greater distance from the object in front of it. However, when the sensor is placed in front of...
Ultrasound is a non-invasive diagnostic tool that uses sound waves to create images. The waves are absorbed or reflected back from different tissue types so they appear brighter or darker on the screen. This technology is ideal for visualizing internal organs and soft tissues as an ultrasound pro...
Other scientists suggest that the technology could eventually allow us to manipulate human memory. Ultrasonic mind control is a science very much in its infancy. With enough research, we might one day live in an age where police use ultrasound to incapacitate you at a protest, while physicians ...
When used correctly, ultrasound instruments are very powerful tools to detect leaks and can greatly contribute in energy saving efforts. Even though leak detection with ultrasound is a very simple and straightforward exercise, it is always advisable for maintenance professionals to get proper training,...
We start with a high level system overview, followed by a more detailed description of how ultrasound systems work. System Introduction Medical ultrasound machines are among the most sophisticated signal processing machines in widespread use today. As in any complex machine, there are many trade-...
Why control algae if nutrients are the problem? What kind of water does your ultrasound work in? What’s the largest water body that LG Sonic has implemented? Any issues linking more buoys? What's the minimum depth of water required for LG Sonic treatment? Products...
Ultrasound is sound with frequencies above the range of human hearing—that is, above 20,000 hertz. Wavelength is the distance between any point on a wave and the corresponding point on the next wave. Technically, sound isdefinedas a mechanical disturbance traveling through an elastic medium —...
