When the photographing image which held down enlargement factor is acquired in, in order to offer the fluoroscopic X-ray apparatus and the x-ray perspective photographing manner which, can register the x-ray detector easily acquire the photographing image, the occasion where the photographing image of the suffering inspection body is acquired on the basis of the perspective image of the suffering inspection body which is displayed in the display, making provision for the x-ray sensing station, the x-ray detector range measurement sensor in order to prevent the collision for x-ray detector portable feature and the x-ray detector which variable it can point distance of x-ray source and, of making use, with the control section the x-ray detector the vicinity of the suffering inspection bodyTo it makes approach, it acquires the photographing image which held down enlargement factor vis-a-vis the perspective image.拡大率を抑えた撮影像を取得する場合において、容易にX線検出器の位置決めを行い、撮影像を取得することができるX線透視撮影装置及びX線透視撮影方法を提供するために、表示装置に表示される被検体の透視像に基づいて被検体の撮影像を取得する際、X線検出部に備えられ、X線源との距離を可変させるX線検出器移動機構と、X線検出器に対する衝突を防止するためのX線検出器距離測定センサーと、を用いて、制御部によってX線検出器を被検体の近傍まで接近させ、透視像に対し拡大率を抑えた撮影像を取得する。
