— A novel approach for blood and wall signal separation in Doppler ultrasound is proposed in the wavelet timescale domain. The Doppler signals of different clutter-to-blood ratios from a femoral artery were simulated and used in the experiments. Compared with the conventional high-pass filtering and the signal separation in the spectrogram, the new method(More)
Parametric, model based, spectral estimation techniques can offer increased frequency resolution over conventional short-term fast Fourier transform methods, overcoming limitations caused by the windowing of sampled, time domain, input data. However, para-metric techniques are significantly more computationally demanding than the Fourier based methods and(More)
