PROBLEM TO BE SOLVED: To set a three-dimensional region of interest (ROI) by using morphing processing.SOLUTION: A three-dimensional ROI generating part 20 sets a three-dimensional region of interest enclosing an object in a three-dimensional image data to be formed by an ultrasonic image forming part 14. That is, a reference cross section setting part 22 sets a plurality of reference cross sections in a three-dimensional data space, a two-dimensional ROI setting part 24 sets two-dimensional regions of interest with respect to each one of the plurality of reference cross sections, and then, a morphing processing part 26 performs the morphing processing with respect to the plurality of two-dimensional regions of interest set with respect to the plurality of reference cross sections. Thus, the three-dimensional region of interest is generated.COPYRIGHT: (C)2009,JPO&INPIT【課題】モーフィング処理を利用して三次元関心領域を設定する。【解決手段】三次元ROI形成部20は、超音波画像形成部14で形成される三次元画像データ内に対象物を取り囲む三次元関心領域を設定する。つまり、基準断面設定部22が三次元データ空間内に複数の基準断面を設定し、二次元ROI設定部24が複数の基準断面の各々に対して二次元関心領域を設定し、モーフィング処理部26が複数の基準断面に設定された複数の二次元関心領域に対してモーフィング処理を施して三次元関心領域を形成する。【選択図】図1
