Summary:To provide an image processing apparatus, method and program capable of reducing the influence of an edge image which is caused by the edge of a compression plate and is included in a projection image acquired by tomosynthesis imaging.SOLUTION: An image acquisition unit acquires multiple projection images corresponding to respective radiation source positions which have been generated by causing an imaging apparatus to perform tomosynthesis imaging for an object compressed by a compression plate. An edge image detection unit detects an edge image caused by the edge of the compression plate in the multiple projection images. A cutout unit cuts out the projection image according to a positional relationship between the edge image and an image of the object to generate a cut-out projection image.SELECTED DRAWING: Figure 3 【課題】画像処理装置、方法およびプログラムにおいて、トモシンセシス撮影により取得される投影画像に含まれる、圧迫板の縁部に起因する縁部像の影響を低減できるようにする。【解決手段】画像取得部が、圧迫板により圧迫された被写体のトモシンセシス撮影を撮影装置に行わせることにより生成された、複数の線源位置のそれぞれに対応する複数の投影画像を取得する。縁部像検出部が、複数の投影画像において、圧迫板の縁部に起因する縁部像を検出する。切り出し部が、縁部像と被写体の像との位置関係に応じて、投影画像を切り出すことにより、切り出し投影画像を生成する。【選択図】図３
