Abstract
(EN)
This radiation imaging device captures a radiation image using a detection means in which a plurality of first pixels sensitive to radiation and a plurality of second pixels not sensitive to radiation are disposed within a pixel region, and is provided with a correction means for correcting a radiation image acquired from the first pixels under radiation on the basis of difference information between an image acquired from the first pixels without radiation and an image acquired on the basis of the output from the second pixels.
(FR)
La présente invention concerne un dispositif d’imagerie par rayonnement qui capture une image de rayonnement à l'aide d'un moyen de détection dans lequel une pluralité de premiers pixels sensibles au rayonnement et une pluralité de seconds pixels non sensibles au rayonnement sont disposés à l’intérieur d’une région de pixel, et est muni d’un moyen de correction pour corriger une image de rayonnement acquise à partir des premiers pixels sous le rayonnement sur la base des informations de différence entre une image acquise à partir des premiers pixels sans rayonnement et une image acquise sur la base de la sortie provenant des seconds pixels.
(JA)
放射線に対して感度を有する第1の画素と、放射線に対して感度を有さない第2の画素とが、画素領域内に複数配置された検出手段を用いて放射線画像の撮影を行う放射線撮影装置は、放射線を照射しない状態で第1の画素から取得した画像と第2の画素からの出力に基づいて取得した画像との差分情報に基づき、放射線を照射した状態で第1の画素から取得した放射線画像を補正する補正手段を備える。
