Abstract
Two-dimensional distribution data of velocities on a moving object in an object to be examined is obtained. A motion field which defines the motion direction of a tissue is stored. A plurality of tracking points are obtained in a tissue range in the two-dimensional distribution data. The moving positions of the tracking points are estimated and the positions are sequentially tracked. Velocities toward the motion direction defined by the motion field are obtained on the basis of the two-dimensional distribution data. One intermediate output value is obtained by performing a predetermined computation by using velocities toward the motion direction at tracking positions of at least two tracking points in each time phase. The values of intermediate positions are obtained by performing weighted addition of intermediate outputs at different positions. A display image is generated and displayed by using the values of the intermediate positions.
