<P>PROBLEM TO BE SOLVED: To suppress the variance in deterioration of a detector. <P>SOLUTION: In a radiation imaging method for obtaining radiation data corresponding to an object (10) by performing an imaging operation of detecting, by a detector (30), radiation irradiating the object and transmitted through the object, a plurality of imaging operations is executed with changes in thickness of areas (R1 to R3) through which radiation reaches a plurality of detection areas (A11 to A14) in the detector, of the object so that a dose of radiation reaching each of the detection areas (for example, a total dose of radiation or an average value of doses of radiation) is converged to a reference value after the execution of the plurality of imaging operations. <P>COPYRIGHT: (C)2012,JPO&INPIT |
