PROBLEM TO BE SOLVED: To provide an X-ray tomography method and apparatus which have a panorama imaging mode and a CT imaging mode switched to each other and having the same common trajectory of rotary arm moving means.SOLUTION: Even when the panorama imaging mode and the CT imaging mode are switched to each other, and has the common image forming trajectory of the rotary arm moving means in panorama imaging and CT imaging, the time and labor of a user for displacing a sensor before imaging can be eliminated, and further, the rotary arm moving means is configured by rotations only.COPYRIGHT: (C)2010,JPO&INPIT【課題】パノラマ撮影モード・CT撮影モードを切り替えても回転アーム移動手段の軌跡が同一で変わらず、それぞれ共通となるX線撮影方法および装置を提供しようとするものである。【解決手段】パノラマ撮影モードとCT撮影モードとを切換えても、回転アーム移動手段の画像形成軌跡は、パノラマ撮影・CT撮影それぞれ共通であり、ユーザーが撮影前にセンサを取り替える手間を省略することができ、その上、回転アーム移動手段を回転のみで構成する【選択図】図2
