发明名称 Tracking clutter filter for spectral & audio doppler
摘要 In an adaptive clutter filter for spectral Doppler imaging using an ultrasound system, the stopband center frequency and/or bandwidth of the clutter filter are effectively adjusted on a short time scale to better eliminate moving clutter while allowing low velocity bloodflow signals to pass through.
