Abstract
A gridarranged with a scattered radiation shielding platefor each column is arranged at a front face of a radiation detector. The distance between the gridand the radiation detectoris desirably a integral multiple of the height of the scattered radiation shielding plate. A true image signal of the pixel column including the shade is estimated from the image signal of the pixel column adjacent to the pixel column including the shade. The scattered radiation distribution is estimated from the image signals of the pixel column including the shade of the scattered radiation shielding plate and the image signals when considering that the shielding plate is not included in the shielded pixel. A clear diagnosis image without influence of scattered radiation is obtained by subtracting the estimated scattered radiation distribution from the estimated image signal distribution.
