Abstract

　この発明の放射線撮像装置は、照視野制御手段によって照視野を狭く絞った状態で検出された放射線に基づく複数の放射線画像を取得する撮像（スロット撮像）を１回で行う。それら複数の放射線画像は、照視野を狭く絞った状態で撮像された画像であるので、中心算出手段によって放射線画像のずれた中心を求めることができる。求められた放射線画像のずれた中心および放射線検出手段の照視野との位置関係からズレ算出手段はＸ線画像の中心のズレを求め、求められたズレに基づいて、複数の放射線画像自身に対してズレを補正するので、１回のスロット撮像でズレを補正することができ、スロット撮像の際に、各画像を取得した時点で中心点を求めたり、一連の画像を取得した後でまとめて中心点を求めたりなどしつつ、ズレを補正することができる。
