PROBLEM TO BE SOLVED: To provide a radiographic system which suppresses the degradation of image quality due to lack of synchronism between a radiation irradiation period and an electric charge accumulation period in a radiographic apparatus.SOLUTION: An FPD cassette control unit of the radiographic system, after reading electric charges from a plurality of radiation detection elements to generate one frame image of a moving image, re-reads electric charges from some of the plurality of radiation detection elements, and determines, based on the amount of re-read electric charges of the radiation detection elements, whether or not radiation is irradiated not in the electric charge accumulation period of the radiation detection elements. When it is determined that radiation is irradiated not in the electric charge accumulation period of the radiation detection elements, the control unit adjusts the electric charge accumulation period such that radiation is irradiated in the electric charge accumulation period for the generation of the next frame image.SELECTED DRAWING: Figure 4【課題】放射線照射期間と放射線撮影装置との電荷蓄積期間の同期のずれによる画質劣化を抑制する放射線撮影システムを提供する。【解決手段】放射線撮影システムのＦＰＤカセッテの制御部は、動画像の一のフレーム画像の生成のために複数の放射線検出素子からの電荷の読み出しを行った後、複数の放射線検出素子の一部から電荷の再読み出しを行い、再読み出しされた放射線検出素子の電荷量に基づいて、放射線検出素子の電荷蓄積期間外に放射線が照射されたか否かを判断し、放射線検出素子の電荷蓄積期間外に放射線が照射されたと判断した場合は、次のフレーム画像の生成において電荷蓄積期間内に放射線が照射されるように電荷蓄積期間を調整する。【選択図】図４
