Automatic De-noising of Doppler Ultrasound Signals Using Matching Pursuit Method

2006
A novel de-noising method, called matching pursuit method, for improving the signal-to-noise ratio (SNR) of Doppler ultrasound blood flow signals is proposed. Using this method, the Doppler ultrasound signal is first decomposed into a linear expansion of waveforms, called time-frequency atoms, which are selected from a redundant dictionary named Gabor ...

[Transcranial Doppler and duplex ultrasound--where is the method helpful?].

Ultraschall in der Medizin (Stuttgart, Germany : 1980), 1994
In recent years transcranial Doppler and duplex sonography have become valuable methods supplementary to extracranial vascular investigations and especially in intensive care medicine. High grade stenoses and occlusions of the basal cerebral arteries as well as vascular spasms after subarachnoidal haemorrhage can be assessed using well-known Doppler ...
