Disclosed herein is an X-ray photographing apparatus. The X-ray photographing apparatus uses a moving source and a tension spring in order to let a grid reciprocate for removing a scattered radiation. The moving source generates moving force moving the grid toward one side, and the tension spring applies tension force moving the grid toward the other side. According to the present invention, since the grid moves at a velocity close to a constant velocity, image quality is improved. |
