  • Patent number: 8167807
    Abstract: A motion parameter measuring unit two-dimensionally measures a motion parameter of a myocardial tissue by a tracking process on time-series ultrasonic image data acquired from a sample. A time phase setting unit adds a diastolic heartbeat time phase, which is set on the basis of a systole end specified by a time phase where a cardiac cavity area of the ultrasonic image data is the smallest and a diastole end specified by an R wave in an electrocardiographic waveform of the sample, relative to the systole end to time-series parameter image data generated by a parameter image data generating unit on the basis of the motion parameter. An image data extracting unit extracts parameter image data to which the diastolic heartbeat time phase closest to a desired diastolic heartbeat time phase set by an input unit is added and displays the extracted parameter image data.

  • Publication number: 20110190634
    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: 7722540
    Abstract: When a two-dimensional tomogram is to be displayed, motion information associated with a direction orthogonal to the tomogram is colored and mapped on the tomogram to be visualized by using the volume data of a TSI image. For example, a mapping image is generated by color-mapping shortening information at each point on a cardiac tissue on a short axis view by using the volume data of the TSI image. Superimposing and displaying the mapping image on the original short axis view makes it possible to simultaneously observe the shortening information even while a short axis view is obtained and observed.

  • Publication number: 20100111380
    Abstract: A motion function of a biological tissue is efficiently evaluated on the basis of image data collected from different medical image diagnostic apparatuses. In terms of a common analysis algorithm applied to subject's time-series image data supplied from a separate medical image diagnostic apparatus, a setting part sets a plurality of interest points on a myocardial tissue of a reference image data extracted from the image data, and a tracking process part measures a motion parameter on the basis of displacement information of the myocardial tissue at the interest points obtained by a tracking process between the reference image data and subsequent image data thereof. Meanwhile, a data creating unit creates parameter image data showing two-dimension distribution of the motion parameter or parameter time-series data showing a variation in time of the motion parameter as parameter data on the basis of the measurement result, and displays the parameter data.
