<P>PROBLEM TO BE SOLVED: To provide X-ray photographing equipment capable of correcting the fluctuation of a pixel value caused by the error of X-ray quantity in a case that photographing is repeatedly executed. <P>SOLUTION: This X-ray photographing equipment is constituted so that the pixel value of an X-ray image measured in measurement on and after the second time is multiplied by the ratio of the integrated value of X rays operated in the first measuring process and the integrated value of X rays operated in the measuring process on and after the second time. Therefore, even in a case that the measurement of bone density is repeatedly executed, the fluctuation of a pixel value caused by the error of X-ray quantity can be corrected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
