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.

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 by transmission and reception of ultrasonic waves to and from a sample. On the other hand, 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 on a display unit.

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： An ultrasound beam is repeatedly transmitted and received to and from an object, so that an echo signal is repeatedly obtained. A velocity of each of a plurality of portions on the ultrasound beam is calculated based on the echo signal. A position of at least one specific portion of the plurality of portions is tracked in as it changes with the passage of time based on the velocity to obtain a path where the specific portion moves. Conventionally the change of brightness of the M-mode image was tracked to obtain the path. According to the present invention, since the path is obtained based on the velocity having high resolution, the accuracy of track can be improved.

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.
