Abstract
An ultrasound diagnostic apparatus including transmitting and receiving devices, and MTI filter units to eliminate clutter components from Doppler data sequences detected trough the transmitting and receiving devices. The diagnostic apparatus further includes A/D converters to convert the Doppler data sequences in analog to those in digital and transient response processing devices provided between the MTI filter units and the A/D converters to suppress influences of transient responses consisted in output signals of the MTI filter units due to at least either one of data discontinuity of the Doppler data sequences at the time starting point or abrupt changes thereof.
