Abstract:
1. A radiographic image capturing apparatus having a plurality of radiation detection units equipped with radiation conversion panels capable of converting radiation into radiographic images and panel accommodating units accommodating the radiation conversion panels therein, and connecting sections for connecting each of the radiation detection units together respectively, wherein: the panel accommodating units each include, respectively, a front surface transmissive to the radiation, a rear surface opposed to the front surface, and side surfaces disposed between the front surface and the rear surface; the connecting sections comprise step portions, which are formed at the side surfaces; the front surfaces of each of the panel accommodating units comprise irradiated surfaces that are irradiated with the radiation that has passed through the subject, and regions within the irradiated surfaces, which are irradiated by the radiation, make up image capturing regions capable of converting the radiation into radiographic images; each of the panel accommodating units comprises a first panel accommodating unit having a first irradiated surface, and a second panel accommodating unit having a second irradiated surface; in the first panel accommodating unit, a surface proximate to step portions of the first panel accommodating unit comprises the rear surface, and a surface opposed to the rear surface and distanced from the step portions makes up the first irradiated surface; in the second panel accommodating unit, a surface proximate to step portions of the second panel accommodating unit makes up the second irradiated surface, and a surface opposed to the second irradiated surface and distanced from the step portions comprises the rear surface; and by interfitting the step portions so that portions of each of the radiation conversion panels are superimposed, and that irradiated surfaces are repeated alternately in a sequence of the first irradiated surface and the second irradiated surface, an image capturing surface of the radiographic image capturing apparatus, which is constituted to include the respective image capturing regions, is maintained in a substantially planar condition.
