| Abstract(in English) | Conventional pulsed ultrasound Doppler technique has a fundamental limitation in the range of Doppler shifted frequency. Alias-free interpolation technique enables to synthesize the Doppler signal with high Nyquist frequency by interpolating the roughly and unequally spaced samples of the Doppler signal.The velocity range is expanded with this technique,and minimum sampling interval is not less than that in conventional technique. This technique is based on the idea that the samples of the Doppler signal can be estimated using a few other samples even though the aliasing is occurring,and this idea can be applied to multi-component Doppler signal. |
