PROBLEM TO BE SOLVED: To achieve an appropriate offset correction in consideration of a form of power supply to a radiographic apparatus.SOLUTION: A radiographic apparatus that can be operated by at least one of a plurality of power supply forms including a battery and an external power source includes a power supply control part for determining a power supply form, and a control part for controlling the operation of the radiographic apparatus. According to the power supply form, the control part switches an acquisition mode between a first acquisition mode for acquiring offset correction data after imaging a subject each time the subject is imaged, and a second acquisition mode for acquiring offset correction data acquired in advance before imaging the subject.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】放射線撮影装置への電源供給の形態を考慮した適切なオフセット補正を実現する。【解決手段】バッテリ及び外部電源を含む複数の電源供給形態の少なくとも1つで動作可能な放射線撮影装置であって、電源供給形態を判定する電源制御部と、放射線撮影装置の動作を制御する制御部と、を備え、制御部は、電源供給形態に応じて、被写体の撮影ごとに当該被写体の撮影後にオフセット補正データを取得する第1の取得モードと、被写体の撮影前に予め取得されたオフセット補正データを取得する第2の取得モードとを切り替える。【選択図】 図1
