PROBLEM TO BE SOLVED: To easily increase an irradiation range of radiation, and apply an optimum dose of radiation to a subject when an image of the subject is captured using a radiation source of field electron emission type at a short SID.SOLUTION: In a radiographic image capturing system and a radiographic image capturing method, an optical image of the subject (14) is acquired by taking an image of the subject (14) with a camera (48) while the subject (14) is disposed between a radiation output device (20) housing at least two radiation sources (18a-18c) and a radiation detecting device (22). Doses of radiation (16a-16c) to be emitted from the at least two radiation sources (18a-18c) are weighted based on the optical image, the radiation (16a-16c) according to the weighting is applied from the at least two radiation sources (18a-18c) to the subject (14), and a radiographic image is thereby acquired.COPYRIGHT: (C)2012,JPO&INPIT【課題】電界電子放出型の放射線源を用いて短いSIDで被写体の撮影を行う場合に、放射線の照射範囲を容易に拡大できると共に、被写体に最適な線量の放射線を照射する。【解決手段】放射線撮影システム及び放射線撮影方法では、少なくとも2つの放射線源(18a~18c)を収容する放射線出力装置(20)と放射線検出装置(22)との間に被写体(14)を配置した状態で、該被写体(14)をカメラ(48)で撮影して被写体(14)の光学画像を取得し、該光学画像に基づいて、少なくとも2つの放射線源(18a~18c)から出力される各放射線(16a~16c)の線量の重み付けを行い、該重み付けに従って少なくとも2つの放射線源(18a~18c)から被写体(14)に放射線(16a~16c)を照射することにより放射線画像を取得する。【選択図】図6
