  • Patent number: 11602333
    Abstract: An ultrasound diagnostic apparatus includes: a transmitter; a receiver; a Doppler processor that detects a Doppler shift frequency resulting from a blood flow in a subject, based on a reception signal corresponding to a reflected wave from a sample gate position in the subject; and a velocity scale adjuster that adjusts a velocity scale determining a pulse repetition frequency, based on a Doppler waveform corresponding to the Doppler shift frequency during an observation target period. In a case where a recommendation value of the velocity scale calculated based on the Doppler waveform is larger than a critical value of the velocity scale at which a measurement state calculated based on the sample gate position transitions from a non-high-pulse-repetition-frequency state to a high-pulse-repetition-frequency state, the velocity scale adjuster sets the critical value as the velocity scale to be used in measurement.
