Summary:To provide an X-ray photographing apparatus that can quickly execute positioning of a subject, regardless of a position of a therapy beam irradiation head.SOLUTION: An X-ray photographing apparatus includes: a first X-ray photographing system comprising a first X-ray tube 11a and a first flat panel detector 21a; a second X-ray photographing system comprising a second X-ray tube 11b and a second flat panel detector 21b; a third X-ray photographing system comprising a third X-ray tube 11c and a third flat panel detector 21c; and a fourth X-ray photographing system comprising a fourth X-ray tube 11d and a fourth flat panel detector 21d. Then, two pieces of X-ray photographing systems where a therapy beam irradiation head is not arranged on an X-ray irradiation area reaching the flat panel detector from the X-ray tube are selected from among the first photographing system to the fourth photographing system, and thereby the X-ray photographing is executed.SELECTED DRAWING: Figure 2 【課題】 治療ビーム照射ヘッドの位置にかかわらず、被検者の位置決めを迅速に実行することが可能なX線撮影装置を提供する。【解決手段】 X線撮影装置は、第1X線管11aと第1フラットパネルディテクタ21aとからなる第1X線撮影系と、第2X線管11bと第2フラットパネルディテクタ21bとからなる第2X線撮影系と、第3X線管11cと第3フラットパネルディテクタ21cとからなる第3X線撮影系と、第4X線管11dと第4フラットパネルディテクタ21dとからなる第4X線撮影系とを備える。そして、第1撮影系から第4撮影系のうち、X線管からフラットパネルディテクタに至るX線の照射領域上に治療ビーム照射ヘッドが配置されていない2個のX線撮影系を選択してX線撮影を実行する。【選択図】 図2
