<p><P>PROBLEM TO BE SOLVED: To effectively and stably make a difference in elasticity into an image with a high S/N even in an arbitrary time phase, concerning elastic image diagnosis. <P>SOLUTION: An RF signal frame data selecting means selects the group of RF signal frame data to be displacement measurement reference. As in the case of the group of present RF signal frame data with the adjacent RF signal frame data or the group of the present RF signal frame data with past RF signal frame data which is obtained by going back for a fixed number of frame intervals from the present data, the means arbitrarily selects the number of the frame intervals between the present RF signal frame data and the past RF signal frame data without fixing the number of the frame intervals in both the groups. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
