PROBLEM TO BE SOLVED: To fit the three-dimensional feeling of auxiliary lines for making it easy to grasp the three-dimensional feeling to that of the specimen contained in a stereoscopic image when the stereoscopic image using a radiation image is displayed.SOLUTION: The auxiliary lines H1 and H2 are applied to two respective radiation images G1 and G2 for displaying the stereoscopic image. The auxiliary lines H1 and H2 comprise a plurality of grids looked so as to be arranged in a depth direction. The auxiliary lines H1 and H2 are formed corresponding to the oppression thickness and photographing technique in photographing of the specimen under oppression and the oppression pressure in photographing of the specimen under oppression.COPYRIGHT: (C)2012,JPO&INPIT【課題】放射線画像を用いた立体視画像を表示するに際し、立体感をつかみやすくするための補助線の立体感と立体視画像に含まれる被検体の立体感とを適合させる。【解決手段】立体視画像を表示するための2つの放射線画像G1,G2のそれぞれに補助線H1,H2を付与する。補助線H1,H2は奥行き方向に並んで見える複数のグリッドからなる。補助線H1,H2は、被検体を圧迫して撮影する際の圧迫厚、撮影手技、被検体を圧迫して撮影する際の圧迫圧に応じて生成する。【選択図】図12
