Overview of TFAST and AFAST: point‐of‐care ultrasounds and how to perform themdoi:10.1002/inpr.95Lewis, DanBassolino, SerenaIn Practice (0263841X)
The wavelength of a sound is the distance the disturbance travels during one cycle. It's related to the sound's speed and frequency by the formula speed/frequency = wavelength. Thismeansthat high-frequency sounds have short wavelengths and low-frequency sounds have long wavelengths. The human ea...

I wanted to meet a good man, one who could love all of me, one who I could start a family with. One day, I did. Courtesy of Jennifer Elliot We got right to it and soon I was pregnant. At my first ultrasound, just eight weeks along, the tech spotted two specks, not one. My ...
It will take years of research and development before LILFU technology is ready to alter human brain circuitry and nonsurgically repair neurological injuries and diseases. As you might imagine, however, the effects of ultrasound on the human brain haven't inspired only therapeutic innovations. Variou...

Tubi is teasing a new arrival on Feb. 9, complete with an ultrasound image that signals a new character is on the way. If you're streaming the Super Bowl here for free, no doubt you'll be watching this ad. Häagen-Dazs: Not so fast or furious ...
Also, waves with long wavelengths generally travel farther than ones with short wavelengths. There are plenty of other things to learn about sound, but this is what you need to know to understand LRAD systems. We'll look at how the LRAD creates sound and takes advantage of these physical ...
Figure 1 shows a simplified diagram of an ultrasound system. In all such systems there is a multi-element transducer at the end of a relatively long (about 2-m) cable. Containing from 48 to 256 micro-coaxial cables, the cable is one of the most expensive parts of the system. In most...
