1. An apparatus for capturing a radiation image, the apparatus comprising:

  • a radiation source configured to emit radiation;

    a wavelength converter having an entrance plane, wherein the wavelength converter is configured to receive the radiation emitted from the radiation source through the entrance plane after the emitted radiation has been transmitted by an object, to convert the received radiation to scintillation light, and to output the scintillation light from the entrance plane;

    a first optical system including at least one lens, the first optical system being configured to focus on the entrance plane and to image the output scintillation light, thereby generating a first radiation image of the object;

    a first image sensor configured to capture the first radiation image;

    a second optical system including at least one lens, the second optical system being configured to focus on an opposite plane that is opposite to the entrance plane in the wavelength converter and to image scintillation light output from the opposite plane, thereby generating a second radiation image of the object; and

    a second image sensor configured to capture the second radiation image.
