Ultrasonic flow meters are non-invasive devices that use acoustic vibrations to determine the flow rate of a liquid. There are two types of ultrasonic flow meters – Doppler and transit time. Both ...

To examine the association of physical activity on maternal–fetal circulation measured by uterine and umbilical artery Doppler flow velocimetry waveforms. Participants included 781 pregnant women with ...

Sometimes, doctors find a way to use technology that hits all the right notes -- it’s easy on your body, gives fast results, and doesn’t cause any side effects. That’s just the case with Doppler ...

The use of sound in medicine started since long time ago. Doctors have used stethoscopes to listen to human body’s internal sounds since the early 19th century and the ultrasound imaging has develop ...

Medical ultrasound is a non-invasive method for imaging the body’s internal structures like organs. It processes by transmitting high-frequency sound waves into the body and measuring the reflections ...
