To provide a radiological imaging system unifiedly managing characteristic information of FPDs, highly efficiently calling the characteristic information and executing a computing process of radiation image data even if using mobile FPDs and a plurality of control terminals in a plurality of radiographic rooms.

When a radiation image detector 6 enters within a predetermined range of any of radiographic rooms, the radiological imaging system transmits identification information read by an RFID tag reader 8 to a control terminal 7 associated to the radiographic room, the control terminal 7 receiving the identification information previously acquires characteristic information corresponding to the identification information received from a management server 2 and, when acquiring radiation image data from the radiation image detector 6 corresponding to the identification information, performs the calculation process of the radiation image data by the acquired characteristic information.
