Simultaneous ultrasonic imaging and doppler display system

摘要

The system has a device responsive to the reception of Doppler information signals producing sequences of Doppler estimation signals during intervals of Doppler signal acquisition. A device responsive to the signals produces signals for use in gaps between the Doppler estimation sequences. A device responsive to Doppler estimation signals preceding a gap derives a first sequence of gapfilling signals over an initial portion of the gap. A device responsive to Doppler estimation signals following the gap derives a second sequence of gapfilling signals over a concluding portion of the gap. A device responsive to the sequences of Doppler estimation signals and the intervening first and second sequences of gapfilling signals displays Doppler information.
