ABSTRACT:
An ultrasonic diagnostic imaging system is provided by which an ultrasonic image and Doppler flow information are simultaneously displayed from echo acquisition sequences alternating between image signal acquisition and Doppler signal acquisition. To continuously display Doppler information during the intervals that images signal acquisition is occurring, these gaps in Doppler signal acquisition are filled by signals derived from the Doppler signals received prior to and succeeding the gaps. The Doppler signals received prior to the gap are used to produce spectrally continuous signals extending over the initial portion of the gap. The Doppler signals received following the gap are used to produce spectrally continuous signals extending over the final portion of the gap. A gapsize calculator is responsive to variations in system scanning parameters to set the durations of the successive image and Doppler signal acquisition intervals to obtain optimal frame rates of display.
