<p><P>PROBLEM TO BE SOLVED: To provide a radiation image photographing device capable of reducing a photographing interval regardless of accumulation time in photographing, when performing the lag correction of a radiation image. <P>SOLUTION: The radiation image photographing device comprises: an image acquisition section for acquiring lag data of the previous radiation image when no radiations are applied before the next photographing, and for acquiring the data of the next radiation image after the next photographing; an offset correction section for performing the offset correction of the lag data in the previous radiation image and the data of the next radiation image; an accumulation time correction section for converting the lag data after the offset correction to data corresponding to the accumulation time of the radiation image data in the next photographing; a lag correction section for performing lag correction by subtracting the lag data after correcting the accumulation time from the data of the next radiation image after the offset correction; and a control section for controlling the operation of the photographing device. The control section performs control so that the lag data are read from the radiation detector in shortened accumulation time that is smaller than the accumulation time in the next photographing. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
