PROBLEM TO BE SOLVED: To provide a radiation imaging system not performing unnecessary X-ray radiation to a subject by reliably performing X-ray cooperation even when wireless communication has failed, in the radiation system including a wireless communication means.SOLUTION: This radiation imaging system includes a radiation generation device R, a radiation image detection part 22, an imaging control means 30, an irradiation detection means 220b, and an image processing part 13. When a control signal of a radiation irradiation start is input from the radiation generation device R or when irradiation of radiation is detected by the irradiation detection means 220b, the imaging control means 30 transfers detection elements into a charge storage state based on the control signal or the detection. The image processing part 13 applies first image processing to an image signal when the imaging control means 30 has transferred the detection elements into the charge storage state by the input of the control signal of the radiation irradiation start, and applies second image processing to the image signal when the imaging control means 30 has transferred the detection elements into the charge storage state by the detection of the irradiation of the radiation by the irradiation detection means 220b.COPYRIGHT: (C)2013,JPO&INPIT【課題】無線通信手段を備えた放射線システムにおいて、無線通信が失敗した場合においても、X線連携を確実に行い、被検体に無駄なX線放射を行うことがない放射線撮像システムを得る。【解決手段】放射線撮像システムは、放射線発生装置Rと、放射線画像検出部22と、撮像制御手段30と、照射検知手段220bと、画像処理部13とを有し、撮像制御手段30は、放射線発生装置Rからの放射線照射開始の制御信号の入力があった場合、および照射検知手段220bによる放射線の照射の検知があった場合に、制御信号や検知に基づいて検出素子を電荷蓄積状態へ移行させ、画像処理部13は、撮像制御手段30が放射線照射開始の制御信号の入力により電荷蓄積状態へ移行させた場合に画像信号に第1の画像処理を施し、撮像制御手段30が照射検知手段220bによる放射線の照射の検知により電荷蓄積状態へ移行させた場合に画像信号に第2の画像処理を施す。【選択図】図1
