Improving Doppler ultrasound spectroscopy with multiband instantaneous energy separation

This paper deals with improving the time-frequency resolution of Doppler ultrasound spectroscopy, applied to blood flow analysis, by developing robust nonstationary spectrum estimation techniques based on Gabor (1946) filterbanks and multiband AM-FM demodulation that uses an instantaneous energy separation algorithm.
