    摘要： An ultrasonic diagnostic apparatus removes a speckle pattern using information on a direction (depth direction) that is substantially orthogonal to a plurality of ultrasonic images included in three-dimensional image data. For example, three-dimensional CFAR processing, two-dimensional CFAR processing, and a depth-direction arithmetic process are performed to discriminate a continuous structure that is three-dimensionally arranged from a local microstructure, thereby generating a microstructure extracted image.

    摘要： According to an embodiment, an image generating unit generates a medical image. A deciding unit detects a reaching time at which a contrast agent has reached a predetermined region of the medical image. The deciding unit sets a color map in which the reaching time is associated with a hue based on a first inflow time corresponding to a first designation region set to the medical image and a second inflow time corresponding to a second designation region. A generating unit generates a hue conversion image in which a hue is allocated to each region of the medical image based on the color map and the reaching time in each region of the medical image. A control unit displays the hue conversion image through a monitor.

    摘要： 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.
