PROBLEM TO BE SOLVED: To provide an image diagnosis support device and an image processing method capable of presenting a judgment basis of a diagnosis result in an arbitrary image diagnosis model. SOLUTION: A model reading unit for reading an image diagnosis model that outputs a diagnosis result for an input medical image, and a determination area extraction unit for extracting a plurality of determination areas from the medical image based on a plurality of determination items. , The diagnosis result obtained by inputting the determination area into the image diagnosis model is acquired while changing the combination of the determination areas, and each of the determination areas is obtained based on each acquired diagnosis result and the combination of the determination areas. It is characterized by including an importance calculation unit for calculating the importance of. [Selection diagram] Fig. 2【課題】任意の画像診断モデルにおいて、診断結果の判断根拠を提示可能な画像診断支援装置および画像処理方法を提供する。【解決手段】入力される医用画像に対して診断結果を出力する画像診断モデルを読み込むモデル読込部と、複数の判定項目に基づいて前記医用画像から複数の判定領域を抽出する判定領域抽出部と、前記画像診断モデルへ前記判定領域を入力して得られる診断結果を、前記判定領域の組み合わせを変えながら取得し、取得された各診断結果と前記判定領域の組み合わせとに基づいて前記判定領域毎の重要度を算出する重要度算出部と、を備えることを特徴とする。【選択図】図２
