Abstract

　この発明のＸ線撮影装置は、自動露出制御部１６でのＸ線照射停止したときのＸ線撮影条件でＸ線管のＸ線照射を行うように制御するとともに、自動露出制御部１６での自動露出制御をオフするＸ線撮影条件固定制御部１７を備えているので、撮影開始時にのみ自動露出制御を行い、そのときのＸ線撮影条件でロックし、自動露出制御をオフとした状態で、以後の連射撮影を行うことができる。また、現在の撮影部位から新たな撮影部位をＸ線撮影する場合には、連射撮影中に天板駆動が検出され、新たな撮影部位での撮影開始時にのみ自動露出制御を行うことができ、そのときのＸ線撮影条件でロックし、自動露出制御をオフとした状態で、以後の連射撮影を行うことができる。その結果、撮影収集モードを設定することなく、適切な自動露出制御を行うことができる。
