Abstract: A radiographic device includes an radiation irradiator which can irradiate a subject with radiation, and which includes a collimator capable of selectively blocking radiation flux; an image acquisition unit for acquiring an image signal by receiving the radiation that has passed through the subject; a display unit for displaying a radiation image on the basis of the image signal; and a determination controller which can control the irradiation unit so that the irradiation range of the radiation corresponding to a selection area selected from the radiation image is implemented.

Abstract: A radiographic device includes a radiation irradiator; an image acquisition unit; a support member; a driving unit driving the support member; a position information detector which detects location information indicating the location of one or more of the radiation irradiator and the image acquisition unit; a storage unit which links reference location information, indicating the location of one or more of the radiation irradiator and the image acquisition unit, with corresponding radiation output information of the radiation irradiator, and stores same as positioning information; and a determination controller which, if the location information detected by the position information detector matches with the reference location information of the positioning information, controls the radiation irradiator so that the radiation irradiator emits radiation according to the radiation output information of the corresponding positioning information.
