It can identify a significantly elevated velocity in the proximal subclavian artery (i.e., >300 cm/s), as well as a change in its waveform from the normal triphasic appearance to a more biphasic ...

Abstract: Empirical investigations show that at low and moderate signal-to-noise ratios, maximum entropy (ME) Doppler shift and spectral width estimates of VHF radar signals have significantly higher ...

An effective numerical approach is developed for orthogonal waveform design for Multiple-Input Multiple-Output (MIMO) radar. The Doppler shift tolerance is considered in the design cost function. The ...

Venous occlusion plethysmography is not the only method available for measurement of forearm blood flow: an alternative is to use a Doppler flow probe placed over the brachial artery. However, this ...
