PROBLEM TO BE SOLVED: To cancel positional change due to heart beats and breathing and leave the influence of the positional change with convergence caused by a tumor.SOLUTION: An image display device comprises: designation means which accepts designation of the area of a tumor portion; identification means which identifies the positions of feature points located a predetermined threshold or more away from the designation-accepted area, among feature points in an image, and the positions of feature points corresponding to the feature points in the other image; and deformation means which deforms the image by using the difference between the identified positions of the feature points.SELECTED DRAWING: Figure 10 【課題】 心拍や呼吸による位置の変動を打ち消す一方で、腫瘍で生じた集束に伴う位置の変動の影響を残すことを目的とする。【解決手段】 腫瘍部分の領域の指定を受け付ける指定手段と、画像中の特徴点のうち、指定を受け付けた領域から所定の閾値以上離れた箇所にある特徴点の位置と、他方の画像における当該特徴点に対応する特徴点の位置を特定する特定手段と、特定された前記特徴点の位置の差を用いて画像を変形する変形手段とを有する。【選択図】図１０
