PROBLEM TO BE SOLVED: To reduce invalid exposure of an operator or health professional.SOLUTION: An X-ray apparatus includes: an X-ray generator 6 for generating X-rays a position detection part 93 for detecting a positional relationship between the X-ray generator 6 and a position measurement object and a determination part 92 for determining permission or denial of X-ray exposure from the X-ray generator 6 according to the detected positional relationship, and inhibiting or permitting the exposure of the X-rays. The position detection part 93 includes, for instance, a radio transmitter 31 for sending out radio signals and a radio receiver 32 provided near the X-ray generator 6, for outputting reception signals on the basis of the received radio signals, and detects the positional relationship between the radio transmitter 31 and the radio receiver 32 on the basis of the reception signals.COPYRIGHT: (C)2014,JPO&INPIT【課題】操作者や医療従事者の無効被ばくの低減を図る。【解決手段】X線を発生させるX線発生装置6と、X線発生装置6と位置計測対象体との位置関係を検出する位置検出部93と、検出された位置関係に応じて、X線発生装置6からのX線曝射の許否を判断し、X線の曝射を禁止又は許可する判断部92と、を備える。位置検出部93は、例えば、無線信号を送出する無線送信器31と、X線発生装置6の近傍に備えられ、受信した無線信号に基づいて受信信号を出力する無線受信器32と、を含み、受信信号に基づいて、無線送信器31及び無線受信器32の位置関係を検出する。【選択図】図2
