摘要： Position coordinate information of each point three-dimensionally forming a tissue corresponding to a diagnosis target at each time phase is obtained, a quantitative value for evaluating the movement of the tissue corresponding to the diagnosis target is calculated by using the position information, and the result is output in a predetermined form. Accordingly, since the quantitative value for evaluating the movement is calculated by using the three-dimensional position coordinate information without converting wall movement information obtained by a three-dimensional tracking process into two-dimensional information, it is possible to provide medical information with a higher degree of precision.

摘要： 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.

摘要： A contour specifying part receives volume data representing a subject acquired by transmission of ultrasonic waves to the subject, and specifies a 3-dimensional contour of a myocardium based on the volume data. A forming part sets a reference point on the contour of the myocardium, and forms an image generation plane including a plane substantially orthogonal to the contour of the myocardium at the reference point. An image generator generates image data on the image generation plane based on the volume data. A display controller controls a display to display an image based on the image data.

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.

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： When displaying a plurality of images in different conformations in relation to information of a tissue motion typified by a heart wall motion, support information which is used to rapidly and easily visually confirm a relative positional correspondence relationship between an MPR image, a polar mapping image, and a three-dimensional image is generated and displayed. A marker indicative of a desired local position is set and displayed as required. Further, a position corresponding to the set or changed marker may not be present on the MPR image. In such a case, the MPR image always including a position corresponding to the set or changed marker is generated and displayed by automatically adjusting a position of an MPR cross section.
