Abstract: The average velocity of a tissue is calculated for each frame in accordance with compression/release, and a reference waveform is generated by using the calculated velocity. A time phase in which the average velocity becomes 0 is specified by the reference waveform. In strain computation, time integration is performed for strain computation in a compression period or a release period with reference to the specified stationary time phase. This can properly and automatically visualize how the contraction of the tissue is accumulated from the start of compression or the contraction of the tissue becomes maximum in a compression end time phase in a compression period and how the tissue expands from the start of release or the expansion of the tissue becomes maximum in a release end time phase in a release time phase.

Abstract: 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.

Abstract: Using three-dimensional mapping images at different time phases obtained by mapping motion information, a peak value of motion information in a local region is retrieved in each of the time phases. On the basis of the result, a locus line or the like indicative of fluctuations with time in the local peak region is generated and displayed so as to be, for example, superimposed on a mapping image. By observing the locus line on the mapping image displayed, the observer can directly grasp the state of the space-time propagation of mechanical excitement of the heart.

Abstract: Three slices, i.e., Basal, Mid, and Apical slices, which correspond to clinically useful ASE segmentation are designated, and the positions of the three slices are tracked through at least one cardiac cycle by performing three-dimensional speckle tracking in the remaining time phases. Three C-mode projection images concerning the tracked positions are reconstructed. In addition, arbitrary myocardial wall motion parameters at the tracked positions are computed and displayed upon being superimposed on C-mode images or projected/displayed on a polar map. As a C-mode projection image method, one of the following techniques can be used detecting and projecting only movement components perpendicular to slices determined in an initial time phase, detecting and projecting average movement components of the respective walls, and tracking and projecting each myocardial position. The obtained C-mode images are simultaneously displayed together with markers indicating the positions of long-axis images and C-mode images.
