Abstract
A radiation image capturing apparatus that includes a radiation conversion panel comprises an input device for inputting a first distance from the position of the panel to a position serving as a reference position for a subject, a distance measuring unit for measuring a second distance from the radiation source to the panel, a first radiation field calculating unit for determining a radiation field at the position of the 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 panel based on the information of the calculated radiation field and the information of the calculated hypothetical radiation field.
