Abstract:
A radiation image recording method, comprising the steps of:i) irradiating radiation to an object, and ii) detecting the radiation, which carries image information of the object, at a plurality of positions for image recording, which are set at different distances from the object, a plurality of radiation images of the object being thereby acquired, wherein the acquisition of the plurality of the radiation images of the object is performed by use of a plurality of two-dimensional detectors, such that the radiation, which carries the image information of the object, at a position for image recording, which is remote from the object, is detected with a two-dimensional detector having a sensitivity higher than the sensitivity of a two-dimensional detector for detecting the radiation at a position for image recording, which is close to the object, and wherein the radiation is at least one of: x-rays, alpha-rays, beta-rays, gamma-rays and cathode rays.
