Doppler Global Velocimetry (DGV) is an optical measurement technique that leverages the Doppler effect to determine velocity fields in complex fluid flow environments. By detecting frequency shifts in ...

QUESTION: Talk about your work in detecting new planets. MARCY: The Doppler technique involves watching a star to see how it is gravitationally pulled by its attendant planets. We are lucky that with ...

Norwood, Mass — Analog Devices, Inc. has created an IC that simplifies the development of continuous wave (CW) Doppler imaging in stationary and portable ultrasound systems. CW Doppler is an advanced ...

DURHAM, N.C. -- Duke anesthesiologists have found that a "Doppler" technique of using reflected sound waves to measure the heart's pumping action can better guide the administration of fluids and ...

The purpose of a Doppler ultrasound is to check blood flow. Doctors use the findings to help determine whether there is a blockage, narrowing, or leakage in a blood vessel. Healthcare professionals ...

When the body moves, it's harder for existing wearable devices to accurately track heart activity. But University of Missouri researchers found that a starfish's five-arm shape helps solve this ...
