1. A radiation image capturing system comprising:
a radiation source for outputting a radiation to pass through a subject; a radiation source control apparatus for controlling the radiation source; a plurality of radiation conversion panels for being irradiated with the radiation which has passed through the subject, having different systems for converting the radiation into radiation image information of the subject; an image capturing condition storage for storing, in advance, image capturing conditions corresponding to the plurality of radiation conversion panels, the image capturing conditions including combinations of a target, a filter, and a tube voltage of the radiation source for outputting the radiation depending on sensitivity characteristics of the plurality of radiation conversion panels; a panel selector for selecting one radiation conversion panel to be used for capturing a radiation image among the plurality of radiation conversion panels; and an image capturing condition setting unit for reading out one of the image capturing conditions depending on the selected one radiation conversion panel from the image capturing condition storage, and setting the read-out one image capturing condition to the radiation source and the radiation source control apparatus; wherein the plurality of radiation conversion panels having different systems include at least a first radiation conversion panel having a solid-state detector for converting radiation directly into electric signals and reading out the electric signals and a second radiation conversion panel having a solid-state detector for converting radiation into visible light with a scintillator and then converting the visible light into electric signals and reading out the electric signals, and wherein the radiation source is adjusted based on the one image capturing condition set by the image capturing condition setting unit, and the adjusted radiation source applies the radiation to the subject.
