1. Ultrasound

   Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasound imaging or sonography is often used in medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning, mixing, and accelerating chemical processes. Animals such as bats and porpoises use ultrasound for locating prey and obstacles.

1. ultrasound

   Ultrasound refers to sound waves with frequencies higher than the upper audible limit of human hearing. This frequency is typically above 20 kilohertz (20,000 hertz). Although this limit varies from person to person, most people are unable to hear sounds in the ultrasound frequency range. It is used in various fields, including medicine, materials testing, industry, and research, most commonly in imaging or probing the inside of objects or bodies.

1. Ultrasound

   Ultrasound is an oscillating sound pressure wave with a frequency greater than the upper limit of the human hearing range. Ultrasound is thus not separated from 'normal' sound based on differences in physical properties, only the fact that humans cannot hear it. Although this limit varies from person to person, it is approximately 20 kilohertz in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. Ultrasound is used in many different fields. Ultrasonic devices are used to detect objects and measure distances. Ultrasonic imaging is used in both veterinary medicine and human medicine. In the nondestructive testing of products and structures, ultrasound is used to detect invisible flaws. Industrially, ultrasound is used for cleaning and for mixing, and to accelerate chemical processes. Organisms such as bats and porpoises use ultrasound for locating prey and obstacles. Ultrasonics is the application of ultrasound. Ultrasound can be used for medical imaging, detection, measurement and cleaning. At higher power levels, ultrasonics is useful for changing the chemical properties of substances.

Examples of Ultrasound in a Sentence

1. Professor Karsten Koenig:

   We use femtosecond laser pulses. We scan the skin and we get signals from the skin, particularly fluorescence, as well as another signal called second harmonic generation. So with these two signals we can build up images and get a precise look into the skin with a high resolution. The resolution is a factor of one thousand (times) better than ultrasound. So now you get the information without taking biopsies; normally you slice them, you stain them, and then a pathologist would look through these sections. Now you can get this information in seconds, labor free and with this fantastic resolution.

2. Scott Kelly:

   Technology has developed significantly since the Russians had the last crewmembers spend that amount of time in space, the types of imaging capability, between MRIs and CAT scans, ultrasound and probably all ways that we collect data, it has gotten better since this was done the last time.

3. Wendie Berg:

   It seemed like a particularly relevant question because in many countries there is no mammography available, there are now low-tech ultrasound devices that produce images of similar quality to devices used in this study.

4. Elizabeth Etkin-Kramer:

   Her feeling is, if something is going on, there is nothing you can do about it, short of termination, i think it would be important to know, and if God forbid she is positive, then we can look closely by ultrasound and get a lot more information.

5. Vishnumurthy Shushrutha Hedna:

   Instead of doing a million tests, we can do the ultrasound, this modality is a non-invasive, simple, cheap procedure which can save lives and can be done by anybody. It can help save thousands of lives.
