    • 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.
