PROBLEM TO BE SOLVED: To cause a user to intuitively recognize the progress of a lesioned part of an organ.SOLUTION: A medical image diagnosis support device acquires a first medical image including an object organ of a patient, and a second medical image which is a second medical image taken at a time different from the time the first medical image is taken, including the object organ of the patient, and generates a first graph indicating a proportion of a lesioned part in a cross section of the object organ in the first medical image, and a second graph indicating a proportion of the lesioned part in a cross section of the object organ in the second medical image. The medical image diagnosis support device specifies the position of a reference cross section of the object organ in the first medical image and the position of a reference cross section of the object organ in the second medical image, and executes control to subject the first graph and the second graph to positioning on the basis of the position of the reference cross section of the object organ in the first medical image, and the position of the reference cross section of the object organ in the second medical image, and display the graphs.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2018,JPO&INPIT【課題】臓器の病変部の進行状況を直感的にユーザに認識させること。【解決手段】患者の対象臓器を含む第1の医用画像と、第1の医用画像と異なる時刻に撮影された第2の医用画像であって、患者の前記対象臓器を含む第2の医用画像とを取得し、第1の医用画像の対象臓器の断面における病変部の割合を示す第1グラフと、第2の医用画像の対象臓器の断面における病変部の割合を示す第2グラフとを生成する。第1の医用画像における対象臓器の基準断面の位置と、第2の医用画像における対象臓器の基準断面の位置とを特定し、第1グラフと第2グラフとを、第1の医用画像における対象臓器の基準断面の位置と、第2の医用画像における対象臓器の基準断面の位置とにより位置合わせをして表示するよう制御する。【選択図】図7
