A research team has developed an extrapolation-based Doppler resolution enhancement algorithm for frequency modulated ...

The common functional brain imaging modalities, including functional magnetic resonance imaging (fMRI) and positron emission tomography, have excellent depth penetration but do not provide good ...

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 ...

Scientists are one step closer to making x-ray vision a reality. They are perfecting radar systems that can detect human activities through barriers and convert the signals to virtual renderings ...

The Indus Doppler Flow Velocity System is a high-frequency, real-time pulsed Doppler measurement tool with built-in data processing software intended to assess small animals' cardiovascular health.

WEST LAFAYETTE, Ind. — Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a ...

Though Doppler seems relatively simple to implement in ultrasound, analog performance in the latest systems has much higher, more-difficult-to-achieve specifications than standard black-and-white ...
