Abstract: A cradle for use with a radiation conversion device includes a cradle for carrying out charging of a radiation conversion device, the cradle being disposed in the vicinity of an image capturing apparatus which captures a radiation image of a subject, the radiation conversion device detecting radiation that has passed through the subject and converting the radiation into image information. The cradle includes a charging processor for carrying out charging with respect to a battery mounted in the radiation conversion device, an image information acquisition unit for acquiring the image information from the radiation conversion device, a correction information generating unit for generating correction information with respect to the radiation conversion device using the acquired image information, and a correction information memory for storing the generated correction information in association with the radiation conversion device.

Abstract: A radiation detection apparatus includes a casing, and a radiation detection device accommodated inside the casing, which detects radiation emitted from a radiation source and having passed through a subject, and converts the radiation into radiation image information. The radiation detection apparatus further includes a data compression circuit, which compresses the radiation image information to thereby create compressed radiation image information, and an infrared light communication unit which converts the compressed radiation image information into an infrared light signal and outputs the infrared light signal.
