Abstract:
1. A radiographic system having a radiation source that irradiates an object with radiation, a source controller that controls the radiation source, and a radiological image detector that receives the radiation passing through the object to detect a radiological image and that has an AEC sensor used to perform 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 comprising: an information acquiring part for acquiring position information of a detection field of an old AEC sensor; a detection field selecting part for selecting a detection field of the AEC sensor so as to match the detection field of the old AEC sensor on the basis of the position information of the detection field acquired by the information acquiring part; and a first storage part for storing source information in which a source ID specific to the radiation source and the position information of the detection field of the old AEC sensor are correlated with each other, wherein the information acquiring part acquires the source ID and acquires the position information by searching for and extracting the position information corresponding to the acquired source ID from the source information.
