20140056409 | RADIATION IMAGE CAPTURING SYSTEM, RADIATION DETECTING APPARATUS, IMAGE CAPTURING BASE AND RADIATION IMAGE CAPTURING METHOD - A radiation image capturing system includes a first image capturing apparatus for capturing a radiation image of a subject, a second image capturing apparatus for capturing a radiation image of the subject, the second image capturing apparatus having a specification different from that of the first image capturing apparatus, an image correcting device for correcting the radiation image of the subject which is captured by the second image capturing apparatus such that the radiation image of the subject which is captured by the second image capturing apparatus has the same magnification as that of the radiation image of the subject which is captured by the first image capturing apparatus, and a display unit for displaying the corrected radiation image. The radiation images captured by the image capturing apparatus of different specifications are corrected to have the same magnification. | 2014-02-27 |
