1. A radiographic system havinga radiation source that irradiates an object with radiation,a source controller that controls the radiation source, anda radiological image detector that receives the radiation passing through the object to detect a radiological image and that has an AEC sensor performing an automatic exposure control of detecting the dose of the radiation passing through the object and stopping irradiation with the radiation from the radiation source when the integrated value of the detected dose reaches a predetermined irradiation-stop threshold,the radiographic system implementing the automatic exposure control by exchanging any one of a detection signal of the AEC sensor and an irradiation stop signal based on a comparison result of the integrated value of the detection signal of the AEC sensor and the irradiation-stop threshold between the source controller and the radiological image detector,the radiographic system comprising:

  • an information acquiring part for acquiring type information on an installation convenience preference type in which convenience in connection between the source controller and the radiological image detector is preferred or an installation convenience non-preference type; and

    a switching part for selectively switching an output format of an automatic exposure control signal so as to exchange the detection signal between the source controller and the radiological image detector when the type acquired by the information acquiring part is the installation convenience preference type, and to exchange the irradiation stop signal between the source controller and the radiological image detector when the type acquired by the information acquiring part is the installation convenience non-preference type.
