PROBLEM TO BE SOLVED: To allow a user to determine a radiation dose measurement region corresponding to an imaging site of a subject and to easily align the radiation dose measurement region with the imaging site.SOLUTION: A radiographic apparatus includes: an imaging unit which includes pixels for generating a radiograph based on radiation transmitted through a subject and pixels for measuring radiation dose and a control unit which controls the projection of radiation by comparison between the measured radiation dose and a threshold value. The radiographic apparatus is also provided with: a region setting unit which sets a radiation dose measurement region of pixels for use in the measurement of radiation dose according to imaging site information of the subject and a region display unit which displays the radiation dose measurement region corresponding to the imaging site information.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】ユーザーが撮影部位に対応した線量計測領域を把握でき、被写体の撮影部位と線量計測領域との位置合わせを容易に行うこと。【解決手段】被写体を透過した放射線に基づく放射線画像を生成する画素と放射線の線量を計測する画素とを有する撮影部と、計測された線量と閾値との比較により放射線の照射を制御する制御部と、を有する放射線撮影装置は、被写体の撮影部位情報に応じて線量の計測に使用する画素の線量計測領域を設定する領域設定部と、撮影部位情報に対応する線量計測領域を表示する領域表示部と、を備える。【選択図】 図1
