PROBLEM TO BE SOLVED: To reduce exposure dose in a radiographic image photographing apparatus.SOLUTION: The radiographic image photographing apparatus can photograph a subject by two photographing methods: two-dimensional photographing and three-dimensional photographing. The radiographic image photographing apparatus acquires information on a thickness of the subject, determines, based on the acquired information on the thickness of the subject, that the method is the two-dimensional photographing when the thickness of the subject is smaller than a predetermined one and the method is the three-dimensional photographing when the thickness is larger than that of the predetermined one, and sets the method of the apparatus to either the two-dimensional photographing or the three-dimensional photographing, based on a determination result.COPYRIGHT: (C)2012,JPO&INPIT【課題】放射線画像撮影装置において、被曝量を低減する。【解決手段】2次元撮影と3次元撮影の2つの撮影方法で被写体を撮影可能な放射線画像撮影装置において、被写体の厚さ情報を取得し、取得された被写体の厚さ情報に基づいて、被写体の厚さが予め定められた所定の厚さよりも薄い場合には2次元撮影、被写体の厚さが前記所定の厚さよりも厚い場合には3次元撮影となるように撮影方法を判断し、この判断結果に基づいて、放射線画像撮影装置の撮影方法を2次元撮影又は3次元撮影に設定する。【選択図】図4
