PROBLEM TO BE SOLVED: To highly accurately switch the visual field of the two-dimensional detector of different vertical axis length and horizontal axis length by a simple configuration.SOLUTION: The X-ray imaging apparatus of this invention is provided with a mechanism for rotating a detection surface centering on one point in a plane including the detection surface of the detector. A rotation center is determined corresponding to a purpose by matching one side of arrangement before rotation and arrangement after the rotation or matching a center line or the like.COPYRIGHT: (C)2009,JPO&INPIT【課題】縦軸長と横軸長の異なる2次元検出器の視野を、簡易な構成で高精度に切り替える。【解決手段】本発明のX線撮像装置は、検出器の検出面を含む面内で当該検出面を1点を中心に回転させる機構を備える。回転中心は、回転前の配置と回転後の配置との一辺を合致させる、中心線を合致させるなど、目的に応じて決定する。【選択図】 図5
