Abstract:
1. An ultrasound diagnostic apparatus, comprising: a detector configured to detect a peak flow velocity of blood flow velocities acquired from Doppler waveforms collected in a time-serial manner or a peak value of average flow velocities of the blood flow velocities as a representative flow velocity for each of a plurality of predefined periods; a determination unit configured to determine a maximum value of a plurality of representative flow velocities by comparing, for the plurality of predefined periods, values of representative flow velocities sequentially output from the detector; a retention controller configured to control a predefined memory to retain maximum waveform information, which is Doppler waveform information that is information on Doppler waveforms, the maximum waveform information being Doppler waveform information collected in one period, of the plurality of predefined periods, in which the maximum value was detected by the determination unit; and a display controller configured to control a predefined display to display the maximum waveform information of the one period, which was retained in the predefined memory with Doppler waveform information having been collected by a present time point.
