<P>PROBLEM TO BE SOLVED: To provide a registration apparatus capable of preventing the turbulence of an image caused by the effect of the shade of a radiation grid in photographing using a radiation detector by precisely adjusting the relative position of the radiation detector and the radiation grid. <P>SOLUTION: This registration apparatus 10 is constituted so as to adjust the relative position of an FPD 4 with an X-ray grid 5. That is, a map (m) in which the position of the FPD 4 is connected with the incident quantity of radiation is formed by the actual irradiation with the radiation and the angle of inclination of the X-ray grid 5 to the FPD 4 is adjusted on the basis of the map (m) so that the width of the shade of absorption foil projected on the detection surface of the FPD 4 becomes small. By this constitution, the adjustment of the relative position of the FPD 4 with the X-ray grid 5 becomes precise and it can be prevented that the image is disturbed by the effect of the shade of the X-ray grid 5 in photographing using the FPD 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
