The process is very similar to ultrasound imaging. However, the sound waves used are within normal hearing range, and they are used to identify objects rather than internal structures. This ...

High intensity focused ultrasound (HIFU) is a novel prostate cancer treatment that minimizes side effect while destroying ...

We can’t hear all levels of sounds. Sound waves with very high frequencies are called ultrasound and our ears can’t detect them. Ultrasound waves have multiple uses including: detecting ...

The work environment for ultrasound technicians is diverse. Many are employed in hospitals, where they may collaborate with ...

Learn the key differences between ultrasonic vs. evaporative humidifiers to determine which is best for your home. Which is ...

The rig uses a 60W ultrasonic transducer, operating at approximately 40 KHz, to generate a standing wave in combination with a reflector – essentially a rigid piece of material off which sound ...

An ultrasound scan is a medical test that uses high-frequency sound waves to create live images from the inside the body. Also called a sonogram or sonography, ultrasounds let doctors see the body’s ...

But a hackier way would be to build a parametric speaker that focuses soundwaves into a narrow beam like [Shane] did with this ultrasonic sound gun. As the directivity of a soundwave depends on ...

We have now observed for this small sound wave-length that, when the sound intensity is slowly increased, the number of these maxima diminishes. Further, the emphasis appears to shift towards the ...

What is a Doppler ultrasound? This noninvasive diagnostic test uses high-frequency sound waves to determine the speed and direction of blood flow in the heart. It is helpful in indicating the presence ...
