PROBLEM TO BE SOLVED: To provide a mobile radiation vehicle which performs radiography appropriately in a smaller space, a radiography device and a radiography system.SOLUTION: The mobile vehicle 12 moves a radiation application section 22 in the direction relative to a holding section 24 holding a radiation detection panel 14. A control section 30 adjusts the radiation angle of the radiation application section 22 to irradiate the radiation detection panel 14 with radiation in accordance with an imaging position, and performs radiography by synchronizing the radiation operation of the radiation application section 22 and the detection operation of the radiation detection panel 14 in accordance with a synchronization method set in a storage section 39.COPYRIGHT: (C)2012,JPO&INPIT【課題】従来の技術に比べて、狭いスペースにおいて、放射線画像の撮影を適切に行うことができる放射線回診車、放射線画像撮影装置、及び放射線画像撮影システムを提供する。【解決手段】回診車12が放射線照射部22を、放射線検出パネル14を保持する保持部24と相対方向に移動させる。また、制御部30が撮影位置に応じて、放射線検出パネル14に放射線が照射されるように、放射線照射部22の放射線の照射角度を調整し、かつ、記憶部39に設定された同期方法に応じて、放射線照射部22の照射動作と、放射線検出パネル14の検出動作とを同期させて、放射線画像の撮影を行う。【選択図】図2
