PROBLEM TO BE SOLVED: To provide a technology advantageous for improving a degree of freedom of an observation region in a transverse direction in a system by which long-length radiography in a longitudinal direction can be performed.SOLUTION: A radiation imaging system that includes radiation imaging devices D1 and D2 having a plurality of pixels arranged in a two-dimensional matrix, and converting a radiation that is irradiated, passing through a subject, to an image signal which becomes a partial image of the subject, and acquires a radiation image of the subject based on a plurality of image signals. A holding part for holding the radiation imaging devices D1 and D2 holds the radiation imaging devices D1 and D2 so as to move them in a direction intersecting with a direction in which positions for acquiring a plurality of partial images line up.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】長手方向の長尺撮影が行えるシステムにおいて短手方向の観察領域の自由度を向上するのに有利な技術を提供する。【解決手段】2次元マトリクス状に配列された複数の画素を有して被写体を透過して照射された放射線を被写体の部分画像となる画像信号に変換する放射線撮像装置D1、D2を有し、複数の画像信号に基づいて被写体の放射線画像を取得する放射線撮像システムにおいて、放射線撮像装置D1、D2を保持する保持部は、複数の部分画像を取得する位置が並ぶ方向と交差する方向に放射線撮像装置D1、D2を移動可能に保持する。【選択図】図1
