Abstract:
1. A radiation image capturing apparatus comprising: a radiation source; a radiation conversion panel for detecting radiation emitted from the radiation source, and which has passed through a subject, and converting the detected radiation into radiation image information; an input device for inputting at least a first distance from a position of the radiation conversion panel to a position serving as a reference position for the subject; a distance measuring unit for measuring a second distance from the radiation source to the radiation conversion panel; a first radiation field calculating unit for determining a radiation field at the position of the radiation conversion panel based on setting information of the radiation source and the second distance; a second radiation field calculating unit for determining a hypothetical radiation field at the reference position of the subject based on the setting information of the radiation source, the first distance, and the second distance; and a life-size correcting unit for correcting the radiation image information from the radiation conversion panel to provide life-sized image information based on the information of the calculated radiation field and the information of the determined hypothetical radiation field.
