<p><P>PROBLEM TO BE SOLVED: To provide a radiation imaging device, acquiring the moving status of radiation imaging. <P>SOLUTION: In this radiation imaging device for obtaining a radiation image, an absorber 7 for a marker is separately provided so that the width of shading 33 in the disposition direction (Y direction) of an absorbing foil 6a to a flat panel type X-ray detector (FPD) 3 of the absorbing foil 5a by X-ray absorption of the absorbing foil 6a is at least larger than the width of one pixel, whereby a grid 6 is so constructed that the width in the disposition direction of an absorbing layer is made partially larger than each space between the pixels. Thus, only the width of shading 33 of a portion provided with the absorber 7 for a marker is larger than the width of one pixel so that even when the positional relationship in imaging shifts, moving of shading can be acquired to acquire the moving status of X-ray imaging. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
