PROBLEM TO BE SOLVED: To provide an X-ray fluoroscopic apparatus capable of capturing images of a subject with the top board surface stuck with no deposits which affect the X-ray images.SOLUTION: An X-ray fluoroscopic apparatus 1 comprises: a top board 102 on which a subject 101 is placed an X-ray imaging system which includes an X-ray generation unit 103 for projecting X rays and an X-ray detection part 104 for detecting X rays projected from the X-ray generation unit, the X-ray generation unit and the X-ray detection part 104 being opposed to each other across the top board a support movement mechanism part 107 for moving the X-ray imaging system along the surface of the top board and a deposit determination unit 116 which determines presence or absence of deposits on the surface of the top board on the basis of an X-ray image of the top board surface captured using the X-ray imaging system and the support movement mechanism part with no subject placed on the top board and a reference image captured in advance, and displays the result of the determination on a display unit.COPYRIGHT: (C)2016,JPO&INPIT【課題】X線画像に影響を与える付着物が天板表面に無い状態で被検体のX線画像を取得するX線透視撮影装置を提供する。【解決手段】X線透視撮影装置1は、被検体101を配置する天板102と、天板を挟んで対向配置されるX線を照射するX線発生部103とX線発生部から照射されたX線を検出するX線検出部104を有するX線撮影系と、X線撮影系を前記天板の表面に沿って移動させる支柱移動機構部107と、X線撮影系及び前記支柱移動機構部を用いて被検体が配置されていない状態で取得された天板のX線撮影画像と、予め撮影しておいた基準画像と、を用いて天板の表面の付着物の有無を判定し、判定結果を表示部に表示させる付着物判定部116とを有する。【選択図】図1
