Claim:
1. An ultrasonic image processing method comprising: generating first tissue motion information in a first period using a first time as a reference, using a first volume data group made of a plurality of pieces of volume data collected in the first period, of cardiac tissue; generating first time-series tissue motion information images in the first period; specifying at least one local area in the first time-series tissue motion information images, which has a value equal to or larger than a predetermined threshold obtained by multiplying a spatial peak value at each time phase by a coefficient of less than one, wherein by increasing a value of the coefficient, a region around a peak point is limitedly extracted, and by decreasing the value of the coefficient, a region of a peak area having expansion is limitedly extracted, by searching for fluctuations with time of the local area, in each of the entire tissue motion information images, and generating first three dimensional propagation information using the fluctuations with time, and including information indicative of correspondence between the local area and a time phase; and displaying the first three dimensional propagation information.
