    • An ultrasound diagnostic apparatus according to an embodiment includes a detector, a determination unit, a retention controller, and a display controller. The detector is 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 predefined period. The determination unit is configured to determine a maximum value in a predefined polarity of a plurality of representative flow velocities. The retention controller is configured to control a memory unit to retain maximum waveform information that is Doppler waveform information of Doppler waveforms collected for a period in which the maximum value was detected. The display controller is configured to control a display unit to display the maximum waveform information with Doppler waveform information having been collected by a present time point.
    • 根据实施例的超声波诊断装置包括检测器,确定单元,保持控制器和显示控制器。 检测器被配置为检测以时间序列方式收集的多普勒波形获取的血流速度的峰值流速或作为每个预定周期的代表性流速的血流速度的平均流速的峰值。 确定单元被配置为以多个代表性流速的预定极性来确定最大值。 保持控制器被配置为控制存储器单元以保留最大波形信息,其是在检测到最大值的时段中收集的多普勒波形的多普勒波形信息。 显示控制器被配置为控制显示单元以当前时间点收集的多普勒波形信息显示最大波形信息。
