PROBLEM TO BE SOLVED: To suppress excessive radiation irradiation onto a subject which is attributed to the delay in information transmission.SOLUTION: A radiation imaging system includes a radiation imaging apparatus for taking an image of a radiation ray that has passed through a subject by the irradiation of the radiation ray, and a communication control apparatus for controlling the communication between a radiation generation apparatus and the radiation imaging apparatus. The radiation imaging apparatus includes communication means for performing communication with the communication control apparatus, and communication control means for executing control so as to transmit irradiation information related to the radiation ray irradiation in priority to the transmission of the image of a radiation ray in an imaging period. The communication control apparatus includes control means for controlling taking of the image of a radiation ray.SELECTED DRAWING: Figure 1【課題】情報送信の遅延に起因した、被験者への過剰な放射線照射を抑制することを目的とする。【解決手段】放射線の照射により被写体を通過した放射線画像を撮像する放射線撮像装置と、放射線発生装置と放射線撮像装置の間の通信を制御する通信制御装置と、を有する放射線撮像システムであって、放射線撮像装置は、通信制御装置と通信を行う通信手段と、撮影期間中、放射線画像の送信に優先して、放射線照射に係る照射情報の送信を行うよう制御する通信制御手段とを有し、通信制御装置は、照射情報に基づいて、放射線画像の撮像を制御する制御手段を有する。【選択図】図１
