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 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： 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.

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.

The detector is configured to detect a peak flow velocity of blood flow velocities acquired from Doppler waveforms collected in a time-serial manner or a peak value of average flow velocities of the blood flow velocities as a representative flow velocity for each predefined period. The determination unit is configured to determine a maximum value in a predefined polarity of a plurality of representative flow velocities. The retention controller is configured to control a memory unit to retain maximum waveform information that is Doppler waveform information of Doppler waveforms collected for a period in which the maximum value was detected. The display controller is configured to control a display unit to display the maximum waveform information with Doppler waveform information having been collected by a present time point.
