Abstract

　オフセット補正の精度を落とすことなく、補正時間を短縮することのできる放射線画像検出装置を提供する。 　電荷を生成し蓄積するフォトダイオード１５２と、フォトダイオード１５２において、放射線が照射されたときに生成する電荷を蓄積時間Ｔ０の間蓄積させた後、蓄積した電荷を撮像信号として読み出す信号読出し回路１７と、フォトダイオード１５２において、放射線が照射されないときに生成する電荷を蓄積時間Ｔ１の間蓄積させた後、蓄積した電荷をオフセット信号として読み出す信号読出し回路１７と、撮像信号に対して、オフセット信号をＴ０／Ｔ１倍した補正信号に基づくオフセット補正を行う画像データ補正部２８と、を備えている。
