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 first radiographic image is acquired by performing first image capturing in which radiation is applied to the subject (14) from at least one of at least two radiation sources (18a-18c), the doses of radiation (16a-16c) output from the at least two radiation sources (18a-18c) are weighted so as to supplement shortage of the dose of the radiation if the dose of radiation in the first image capturing shown in the first radiographic image has not reached an optimum dose for the subject (14), and in accordance with the weighting, second image capturing is carried out, in which the respective 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から被写体(14)に放射線を照射する1回目の撮影を行うことにより1回目の放射線画像を取得し、該1回目の放射線画像の示す1回目の撮影での放射線の線量が、被写体(14)の最適な線量に到達していない場合には、不足分の線量を補うように、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2回目の撮影を行う。【選択図】図5
