Abstract: Airborne synthetic aperture radar (SAR) systems are commonly susceptible to trajectory deviations, resulting in distinct azimuth phase errors in the ...
AIMS To identify the patent ductus arteriosus (PDA) shunt flow pattern using Doppler echocardiography; and to assess whether it could be used to predict the development of clinically significant PDA.
Background Power Doppler ultrasound (US) of synovial tissue has become an important tool for estimating inflammatory activity in rheumatoid arthritis (RA). Most studies are currently using the ...
This is even more common with Doppler radars due to their higher sensitivity. As you move further away from the radar, the returned echo becomes weaker. This occurs because as the radar beam broadens ...
