PROBLEM TO BE SOLVED: To allow a user to efficiently search for a corresponding region on a two-dimensional image which corresponds to a region of interest in a three-dimensional image.SOLUTION: An information processing apparatus is capable of projecting a given region (e.g., a region of interest or a lesion of interest) in a three-dimensional image (e.g., an MRI image or an X-ray CT image) onto a plane including a two-dimensional image (e.g., ultrasonic image) of an object, and causes display means to display an error range caused by projection (a range where a corresponding region of the region of interest in the two-dimensional image may exist, also referred to as a search range) including the projected region in such a manner that the error range is overlaid on the two-dimensional image.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 ユーザが三次元画像の注目領域に対応する二次元画像上の対応領域を効率良く探索できること。【解決手段】 本発明に係る情報処理装置は、被検体の二次元画像(例えば、超音波画像。)を含む平面上に三次元画像(例えば、MRI画像やX線CT画像。)の所定の領域(例えば、注目領域や注目病変部。)を投影することができ、該投影した投影領域を含む該投影による誤差範囲(注目領域に対応する二次元画像上の対応領域の存在し得る範囲、探索範囲とも呼ぶ。)を該二次元画像上に重ねて表示手段に表示させる。【選択図】 図1
