Abstract
One object of this invention is to provide radiography apparatus with suppressed exposure to a subject in tomography mode. An FPD provided in X-ray apparatus according to this invention converts X-rays into electric signals, and thereafter amplifies the signals to output them to an image generation section. According to this invention, an amplification factor is higher in a tomography mode than in a spot radiography mode. A tomographic image is obtained through superimposing two or more fluoroscopic image. In comparison of the fluoroscopic images, they differ from one another in appearance of the false image. Accordingly, superimposing the images may achieve cancel of the false images. In this way, the tomographic image finally obtained has no false image.
