To check the lymph nodes, you have an ultrasound. Ultrasound scans use high frequency sound waves to create a picture of a part of the body. If doctors find any abnormal areas, they can use the ...

as well as a host of other life-changing medical questions with the help of ultrasound technology. Beyond babies, sonograms are used to help diagnose medical conditions by creating images of body ...

These creatures depend on echolocation, a sophisticated biological sonar system, to maneuver in pitch-black environments. By emitting high-frequency sounds and listening for the returning echoes, bats ...

Apr. 3, 2025 — While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy ...

Introduction: In this in silico, in vitro, and in vivo study, we propose metrics for the characterization of highly scattering media using backscattered acoustic waves in the MHz range, for ...

It uses the same high-frequency sound waves that bats use for echolocation, and that an OBGYN uses to image a fetus. At Delray, the ultrasound is turned into a weapon through a piece of headgear ...

It's free, simple and secure. The images produced from an ultrasound, a milestone in many pregnancies, are called sonograms. They're part of routine pregnancy care, but you may pay some-out-pocket ...

enabling it to avoid obstacles and orient itself in complex environments while climbing backward—especially when other sensory abilities like vision and echolocation are limited. The study found ...

Add a description, image, and links to the 3d-ultrasound topic page so that developers can more easily learn about it.

You’re likely to get a "diagnostic mammogram” and an ultrasound at your follow-up appointment. The diagnostic mammogram might take longer than your routine screening mammogram did, because the ...
