<P>PROBLEM TO BE SOLVED: To easily expand the irradiation range of radiation and apply an optimal dose of radiation to a subject in the case of photographing the subject with a short SID using a field electron emission type radiation source. <P>SOLUTION: In the radiographic image capturing system and radiographic image capturing method, at least three radiation sources (18a-18g) are divided into at least three groups (54-58) including one or more radiation sources. The doses of respective radiation (16a-16g) are weighted so that the doses of radiation (16a, 16b, 16f, 16g) output from the radiation sources (18a, 18b, 18f, 18g) belonging to the groups (54, 58) at both ends with respect to the geometric center position of the radiation sources (18a-18g) are maximum doses, and the doses of radiation (16c-16e) output from the radiation sources (18c-18e) belonging to the group (56) in the vicinity of the geometric center position are low. <P>COPYRIGHT: (C)2012,JPO&INPIT |
