| Abstract: | A time-domain estimation method of mean velocity for Doppler Ultrasound blood flow signal is described. With computer generated Doppler signals, methods of frequency-analysis, zero-crossings and time-domain estimation have been compared. Finally it is pointed out that time-domain estimation method is not only easy to realize, but also as good as frequency-analysis and better than zero-crossings. |
