  • Patent number: 10813621
    Abstract: An analyzer in an embodiment includes processing circuitry. The processing circuitry identifies at least a part of a contour of a heart of a subject for an image corresponding to a first cardiac time phase and an image corresponding to a second cardiac time phase that are included in time-series images including the heart of the subject. The processing circuitry calculates, using the information about the identified contours, a first cardiac function parameter representing at least one of a volume or an ejection fraction of a heart chamber and a second cardiac function parameter representing a global strain of a myocardium corresponding to the heart chamber. The processing circuitry causes the first cardiac function parameter and the second cardiac function parameter to be displayed by common operation.

  • Publication number: 20160367221
    Abstract: An ultrasound diagnosis apparatus generates first data, based on a result of transmission and reception that are executed when a probe is located at a first position of a subject. The apparatus generates second data, based on a result of transmission and reception that are executed when the probe is located at a second position. Under a first constraint on an orientation of a section, the apparatus extracts, from the first data, first sectional image containing a structural object inside the subject and taken along a direction in which the object extends. Under a second constraint on the orientation of a section, the apparatus extracts, from the second data, second sectional image containing the object and taken along a direction in which the object extends. The apparatus generates joined image data composed of at east a part of the first sectional image and the second sectional image joined together.

  • Publication number: 20150173721
    Abstract: An ultrasound diagnostic apparatus includes an alignment unit, a detector and a generator. The alignment unit performs alignment between three-dimensional ultrasound volume data and three-dimensional different-type medical image volume data of a type other than the three-dimensional ultrasound volume data. The detector specifies the position of a luminal area on the different-type medical image volume data and detects the specified position of the luminal area on the ultrasound volume data. The generator generates, as display image data to be displayed on a given display unit, projection image data obtained by projecting the ultrasound volume data from a viewpoint that is set in the luminal area on the basis of the position of the luminal area that is detected by the detector.

  • Patent number: 8540636
    Abstract: In general, according to one embodiment, an ultrasonic diagnostic apparatus includes an image generating unit configured to generate medical images from a multislice which covers an area including the heart of an object. Each slice is almost perpendicular to the long axis of the heart. Each medical image is a short-axis image of the heart. A series of medical images captured at different times correspond to each slice. The embodiment generates a polar map associated with myocardial motion indices from a plurality of medical images. A polar map is segmented into segments. The embodiment calculates the average value of motion indices for each segment. The utility of an average value depends on the range covered by each segment. This embodiment matches the boundary of a segment with the position of a vein. This prevents a deterioration in the utility of average values due to the influences of veins.

  • Patent number: 8520927
    Abstract: 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.

  • Patent number: 8306606
    Abstract: 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.

  • Patent number: 7991108
    Abstract: 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.
