- 摘要：
PROBLEM TO BE SOLVED: To provide a radiographic apparatus acquiring a radiation transmission image suitable for diagnosis even when the behavior of a detecting element (undefined element) temporarily showing a defective property of the movement included in the radiographic apparatus is under an unstable condition.
SOLUTION: The X-ray imaging apparatus 1 prepares two maps used for removing a movement defective element reflected in the radiation transmission image. One of them is selected and the movement defective element reflected in the image is removed. A selecting section 16 selects either map for using. The selecting section 16 catches the radiation detecting element reduced over time which can not detect X-ray, and when the variation of increase and decrease is lowered to a predetermined level, the second map is selected as substitute for the first map. The result is that the defective movement detecting element reflected in the image is accurately removed, and regardless of the stability of FPD4, the radiation transmission image suitable for diagnosis can be always acquired.
