    • A region-of-interest setting unit sets a region of interest to be included in an ultrasound image. A first movement-amount calculating unit sequentially calculates a movement amount of the set region of interest between reception data along the time sequence as a first movement amount. A transmitting-receiving delay-amount computing unit computes a delay amount for sequentially shifting a scan region of an ultrasonic beam based on the sequentially calculated first movement amount. A computation/control circuit performs control so as to generate a high voltage pulse based on the computed delay amount. A second movement-amount calculating unit sequentially calculates a movement amount of the region of interest between image data along the time sequence as a second movement amount. A display-position correcting unit performs a correction such that the region of interest included in the image data is to be displayed at the same display position, based on the second movement amount.
    • 感兴趣区域设置单元设置要包括在超声图像中的感兴趣区域。 第一移动量计算单元顺序地计算沿着时间序列的接收数据之间的设定区域的移动量作为第一移动量。 发送接收延迟量计算单元基于顺序计算的第一移动量来计算用于顺序地移动超声波束的扫描区域的延迟量。 计算/控制电路基于所计算的延迟量来执行控制以产生高电压脉冲。 第二移动量计算单元顺序地计算沿着时间序列的图像数据之间的关注区域的移动量作为第二移动量。 显示位置校正单元基于第二移动量执行校正,使得包括在图像数据中的感兴趣区域将被显示在相同的显示位置。
