<p><P>PROBLEM TO BE SOLVED: To provide a radiographic imaging apparatus capable of removing offset part caused by lag from image data accurately in continuous imaging or image paste. <P>SOLUTION: A radiographic imaging apparatus 1 makes the radiation transmit and reach one part of radiation detecting elements 7 where the radiation incidents without an imaging subject Hu, and it has a marker 43 having a plurality of sections 43a-43d with different transparency ratio ta-td of radiation, and the radiation dose I is estimated based on each image data d(43a)-d(43d) at each image area R(43a)-R(43d) where the sections 43a-43d of the marker 43 are imaged respectively, and a control device 22 estimates offset lag part Olag, where the lag generated by the former radiation imaging is overlapped with each image data d readout during the latter radiation imaging, based on the radiation dose I, and the control device computes the real image data d<SP>*</SP>by substraction treatment of the offset lag part Olag, which is generated by the lag estimated from each image data d readout during the latter radiation imaging. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
