Summary:PROBLEM TO BE SOLVED: To provide a radiographic imaging system capable of reliably preventing an image in which a subject is not photographed from being displayed in an image display device even if a delay occurs in the transmission of an unlock signal from a radiographic imaging device to a control unit.SOLUTION: In a radiographic imaging system 100 that irradiates a radiation X onto a subject H a plurality of times and photographs a moving image, a control unit 70 transmits a synchronous signal S1 for reading to a radiographic imaging device 1, transmits a synchronous signal Sx for irradiation to a radiation irradiation device 50, and executes synchronous control between the radiographic imaging device 1 and the radiation irradiation device 50, adds additional information to the synchronous signal S1 for reading to be transmitted to the radiographic imaging device 1 after the transmission of the synchronous signal Sx for irradiation to the radiation irradiation device 50 is started, and transmits the synchronous signal S1 for reading. The radiographic imaging device 1 receives the synchronous signal S1 for reading to which the additional information is added, from the control unit 70, and then transfers image data D to an image display device 60.SELECTED DRAWING: Figure 4 【課題】放射線画像撮影装置から制御ユニットへのアンロック信号の送信に遅延が生じても、画像表示装置に被写体が撮影されていない画像が表示されることを的確に防止可能な放射線画像撮影システムを提供する。【解決手段】被写体Hに放射線Xを複数回照射して動画撮影を行う放射線画像撮影システム100において、制御ユニット70は、放射線画像撮影装置1に読出用同期信号S1を送信し、放射線照射装置50に照射用同期信号Sxを送信して、放射線画像撮影装置1と放射線照射装置50との同期制御を行うとともに、放射線照射装置50への照射用同期信号Sxの送信を開始した後に放射線画像撮影装置1に送信する読出用同期信号S1に付加情報を付加して送信し、放射線画像撮影装置1は、制御ユニット70から付加情報が付加された読出用同期信号S1を受信してから画像表示装置60に画像データDを転送する。【選択図】図4
