Reconstruction of maximum blood flow velocity waveforms from Doppler ultrasound measurements

This paper presents a novel algorithm for the extraction of maximum blood flow velocity waveforms from Doppler measurements. This method is based on the short-term integrated spectrum of the Doppler signal, and does not require a pre-selected threshold level to deal with the background noise. Experi...

Description
Summary:This paper presents a novel algorithm for the extraction of maximum blood flow velocity waveforms from Doppler measurements. This method is based on the short-term integrated spectrum of the Doppler signal, and does not require a pre-selected threshold level to deal with the background noise. Experimental results indicate that this method is more robust and better suited for the maximum frequency estimation than currently used methods.
