Abstract: | A time domain mean frequency estimator is proposed for use in the two-dimensional real-time Doppler ultrasound blood flow imaging system. Since the frequency domain techniques require a long observation period to resolve the frequency content of the Doppler signal spectrum, it is unsuitable for real-time two-dimensional applications. Performance characteristics of the Doppler mean frequency estimator are obtained using a computer simulation, which models the Doppler signal and the signal processing network. |
