PROBLEM TO BE SOLVED: To provide an X-ray fluoroscopic apparatus which allows an operator to easily confirm and correct an imaging range while reducing exposure of a subject.SOLUTION: A control part 50 comprises as a functional configuration: an imaging processing section 51 which executes various imaging processing such as display of an X-ray image on a display part 41 on the basis of an X-ray detected by an X-ray detector 14 an image acquisition section 52 which acquires an X-ray image for an instruction of fluoroscopy and a movement control section 53 which controls the operations of an X-ray tube movement mechanism 21, a top board movement mechanism 22 and an X-ray detector movement mechanism 23. The movement control section 53 executes such calculation as to convert the movement amount of the X-ray image moved on the screen of the display part 41 with the action of the image processing section 51 into the movement amounts in the longitudinal direction of a bed of the X-ray tube 12 and the X-ray detector 14 and the movement amount in the short direction of the bed of the top board.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2016,JPO&INPIT【課題】被検体の被曝を低減しつつ撮影範囲の確認および修正を容易に行うことが可能なX線透視撮影装置を提供する。【解決手段】制御部50は、機能的構成として、X線検出器14が検出したX線にもとづくX線画像の表示部41への表示等の各種画像処理を実行する画像処理部51と、透視の指示に対してX線画像を取得する画像取得部52と、X線管移動機構21、天板移動機構22およびX線検出器移動機構23の動作を制御する移動制御部53を備える。さらに、移動制御部53は、画像処理部51の作用により表示部41の画面上で移動させたX線画像の移動量を、X線管12およびX線検出器14の寝台の長手方向の移動量、ならびに、天板の寝台の短手方向の移動量に換算する演算を実行する。【選択図】図5
