PROBLEM TO BE SOLVED: To easily understand a three-dimensional positional relationship of auxiliary information on a medical image.SOLUTION: A medical image diagnostic apparatus includes: a medical image acquisition means that acquires the medical image of three-dimensional volume data projected from a prescribed visual point an auxiliary information acquisition means that acquires two or more pieces of auxiliary information related to a three-dimensional coordinate of the volume data a distance reading means that reads the distance between the visual point and each of the two or more pieces of auxiliary information and an auxiliary information display means that controls the transparency or luminance of the two or more pieces of auxiliary information based on the distance, superimposes the two or more pieces of auxiliary information on the medical image, and displays it.COPYRIGHT: (C)2012,JPO&INPIT【課題】 医用画像上で付帯情報の3次元的な位置関係を容易に把握する。【解決手段】 所定の視点から3次元のボリュームデータを投影した医用画像を取得する医用画像取得手段と、前記ボリュームデータの3次元座標に関連付けられた複数の付帯情報を取得する付帯情報取得手段と、前記視点と前記複数の付帯情報それぞれとの距離を読み取る距離読取手段と、前記距離に基づいて前記複数の付帯情報の透明度あるいは輝度を制御して、前記複数の付帯情報を前記医用画像に重畳して表示する付帯情報表示手段とを有することを特徴とする。【選択図】 図5
