PROBLEM TO BE SOLVED: To provide an X-ray photographing device capable of easily comparing sections of a first region and a second region corresponding to each other even when individually photographing moving images of the first region and the second region including the parts of an object to be examined corresponding to each other.SOLUTION: An X-ray photographing device 100 includes: an X-ray tube 1 for irradiating an object to be examined 10 with an X-ray an FPD 2 for individually photographing moving images of a left lower limb and a right lower limb of the object to be examined 10 based on the X-ray that has transmitted the object to be examined 10 two lower limbs image synchronization processing part 6 for synchronizing a first image 71 photographing the left lower limb of the object to be examined 10 and a second image 72 photographing the right lower limb of the object to be examined 10 and a monitor 7 for displaying the synchronized first image 71 and second image 72 so as to compare the mutually corresponding parts of the left lower limb and the right lower limb.COPYRIGHT: (C)2015,JPO&INPIT【課題】被検体の互いに対応する部分を含む第1部位および第2部位を別個に動画撮影した場合でも、第1部位および第2部位の互いに対応する部分を容易に比較することが可能なX線撮影装置を提供する。【解決手段】このX線撮影装置100は、被検体10にX線を照射するX線管1と、被検体10を透過したX線に基づいて被検体10の左下肢および右下肢を別個に動画撮影するFPD2と、被検体10の左下肢を撮影した第1画像71と被検体10の右下肢を撮影した第2画像72とを同期させる両下肢画像同期処理部6と、同期された第1画像71および第2画像72を、左下肢および右下肢の互いに対応する部分が比較可能なように表示するモニタ7とを備える。【選択図】図1
