摘要： For a three-dimensional region including a treatment target site of a patient, a puncture needle scanning region R1 having a slice thickness d1 is set with reference to a cross section (a puncture cross section) including an insertion direction of a puncture needle. Subsequently, in the y-direction substantially perpendicular to the puncture cross section, two treatment target scanning regions R2 (R21 and R22) each being adjacent to the puncture needle scanning region R1 and having a slice thickness d2 are set. Then, based on volume data in the puncture needle scanning region R1 acquired by first three-dimensional scan with ultrasound waves and volume data in the treatment target scanning regions R2 acquired by second three-dimensional scan performed at a lower volume rate than the first three-dimensional scan, image data is generated for the purpose of supporting puncture.

摘要： A differential-image creating unit creates a three-dimensional image on which an artery is highlighted and a three-dimensional image on which a tumor is highlighted. An image compositing unit combines the three-dimensional images to composite an image. A display control unit displays the composite image on a monitor. Moreover, when compositing an image, the image compositing unit composites the image such that a tumor nutrient blood-flow inside and outside tumor is to be displayed in respective different colors. Furthermore, a blood-flow quantity inside tumor measuring unit calculates a blood-flow quantity inside tumor and a ratio of the blood-flow quantity inside tumor to a tumor volume, and the display control unit displays the blood-flow quantity inside tumor and the ratio of the blood-flow quantity inside tumor to the tumor volume. Accordingly, information that is meaningful for determining malignancy of a tumor can be provided.

摘要： A tumor region setting section sets a liver tumor region for a plurality of ultrasonic image data along a time series acquired by ultrasonically capturing a subject to which a contrast agent has been administered. A TIC generator obtains a time change indicating a time change of the pixel values in the liver tumor region based on the plurality of ultrasonic image data along the time series. A peak-detection section specifies a peak point of the time change and obtains the time and pixel value of that peak point. A first determination section determines the degree of malignancy of the liver tumor based on the time and pixel value of the peak point. A display controller displays the degree of malignancy on a display section.

摘要： A cardiac cavity region specifying part specifies the position of a cardiac cavity region represented in volume data. An image generation plane determining part determines an image generation plane that includes a rotation axis intersecting the cardiac cavity region. With a direction orthogonal to the image generation plane as a view direction, a first image generator generates three-dimensional image data that three-dimensionally represents a region excluding the cardiac cavity region, based on data excluding data included in the cardiac cavity of the volume data. A second image generator generates two-dimensional image data that two-dimensionally represents a region in the image generation plane, based on the data excluding the data included in the cardiac cavity region of the volume data. An image synthesizer synthesizes the three-dimensional image data with the two-dimensional image data. A display controller causes a display to display the synthesized image.
