PROBLEM TO BE SOLVED: To provide an ultrasonic diagnosis apparatus which can display stably the images of a predetermined site of a subject to represent in real time so that the images always may face a three-dimensionally identical direction and may be observed from an identical view point.SOLUTION: The three-dimensionally positional deviations in 3D ultrasonic data are successively detected, and the positional deviations successively detected are based to correct the positional deviations in a plurality of 3D ultrasonic data. The image data of a subject contained in the plurality of 3D ultrasonic data are mated with each others in position for the images to face to a three-dimensionally constant direction, and then the ultrasonic volume data successively mated in position are displayed on a monitor 5.COPYRIGHT: (C)2011,JPO&INPIT【課題】リアルタイムに表示される被検体の所定部位の像を常に3次元的な同一方向及び同一向きとして安定して表示すること。【解決手段】3D超音波データの3次元的な位置ずれを逐次検出し、逐次検出される位置ずれに基づいて複数の3D超音波データの位置ずれを補正し、複数の3D超音波データに含まれる被検体の画像データを3次元的な一定の向きに位置合わせし、逐次位置合わせされた超音波ボリュームデータをモニタ5に表示させる。【選択図】図1
