摘要： In time phases except a first time phase, a contour tracking part tracks the position of a region of interest based on image data acquired in each of the time phases. A re-tracking part receives correction of the position of the region of interest in a second time phase, and obtains the position of the corrected region of interest in and after the second time phase based on the image data acquired in and after the second time phase. From position information of the region of interest in and before the second time phase and position information of the corrected region of interest in and after the second time phase, a position calculator obtains position information of the region of interest in all the time phases. A computing part obtains motion information of a tissue within the region of interest based on the position information of the region of interest.

摘要： 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.

摘要： An ultrasound diagnostic apparatus 1 comprises an ultrasonic probe 2 for transmitting the ultrasound while three-dimensionally scanning, and receiving ultrasound reflected from biological tissue, an image processor 5 (and a signal processor 4) for generating image data for an MPR image based on results received thereof, an information memory 6 for storing cross-sectional-position information D showing a cross-section of this MPR image, a display part 81, and a controller 9. The image processor 5 generates image data for the new MPR image for the relevant cross-sectional position, based on the cross-sectional position shown in the cross-sectional-position information D1 obtained when the MPR image was obtained in the past and the received results obtained by the new three-dimensional scan performed with the ultrasonic probe 2. The controller 9 causes the display part 81 to display the new MPR image.

摘要： 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.

摘要： 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.
