    • An ultrasonic diagnostic apparatus has a probe, an ultrasonic wave control unit, a volume data generation unit, and a three-dimensional display processing unit. The ultrasonic wave control unit controls the probe to transmit low-sound-pressure pulses to a scan region at a first pulse repetition period as well as controls the probe to receive an echo corresponding to the low-sound-pressure pulses. Further, the ultrasonic wave control unit controls the probe to transmit high-sound-pressure pulses to the scan region at a second pulse repetition period smaller than the first pulse repetition period. The volume data generation unit generates volume data based on the echo received by the probe under the control of the ultrasonic wave control unit. The three-dimensional display processing unit generates three-dimensional image data by performing a rendering process based on the volume data, and controls display of the three-dimensional image data on a monitor.
    • 超声波诊断装置具有探针,超声波控制部,体数据生成部以及三维显示处理部。 超声波控制单元控制探头以低音压脉冲在第一脉冲重复周期向扫描区域发送,并且控制探头以接收对应于低声压脉冲的回波。 此外,超声波控制单元控制探头以比第一脉冲重复周期小的第二脉冲重复周期将高声压脉冲发送到扫描区域。 音量数据生成单元在超声波控制单元的控制下,基于由探头接收到的回波来生成体数据。 三维显示处理单元通过基于体数据进行渲染处理来生成三维图像数据,并且在监视器上控制三维图像数据的显示。
