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, a pre-exposure image is acquired by performing pre-exposure in which radiation (16b) is applied to the subject (14) from at least one (18b) of at least two radiation sources (18a-18c), the doses of respective radiation (16a-16c) output from the at least two radiation sources (18a-18c) are weighted on the basis of the pre-exposure image, and in accordance with the weighting, a main exposure image is acquired by performing main exposure in which the radiation (16a-16c) is applied to the subject (14) from the at least two radiation sources (18a-18c).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)のうち、少なくとも一方の放射線源(18b)から被写体(14)に放射線(16b)を照射するプレ曝射を行うことによりプレ曝射画像を取得し、該プレ曝射画像に基づいて、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)を照射する本曝射を行うことにより本曝射画像を取得する。【選択図】図5
