<P>PROBLEM TO BE SOLVED: To provide an X-ray radiographic apparatus, capable of setting automatically the optimum number of integration times of X-ray detection output by input of information on accuracy required for a radiogram, without having to depend on operator's experience, or the like. Ž<P>SOLUTION: This apparatus is provided with: an input means for inputting the information on accuracy required for the radiogram; and a detector output integration number-of-times setting means, wherein radiographic condition is set, which includes a tube voltage of an X-ray generation device 1 and a distance between the X-ray generation device 1 and an X-ray detector 3, and does not include the number of integration times of pixel output from the X-ray detector 3; thereby a relation between the number of integration times of each pixel output, when an approximately uniform X-ray enters a plurality of pixels of the X-ray detector 3 under the condition and mutual dispersion of integrated values of each pixel output, is determined; and the number of integration times is calculated and set automatically, capable of acquiring accuracy from the relation and the information on accuracy inputted by the input means 15. As a result, X-ray radiograph in the smallest number of integration times becomes possible, while acquiring a radiogram having the inputted accuracy. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
