PROBLEM TO BE SOLVED: To solve a problem that, if a sample is radiographed with weak X rays of the order not saturating a detector for a thinner portion of the sample, information is not obtained at all or noise is increased for a thicker portion thereof in a visual field of photographing because of decreased amount of X rays, when the sample is fluoroscopically radiographed with X rays. SOLUTION: This X-ray radiographing method is used for an X-ray radiographing device made up of an X-ray generator and a detector provided in a position opposed to the X-ray generator and used for radiographing the sample put between the X-ray generator and the detector. A tube current of the X-ray generator is varied at least two times and received by the detector. At least two images received by the detector are synthesized. |
