PROBLEM TO BE SOLVED: To provide an X-ray image diagnostic apparatus which suppresses the possibility of ineffective exposure even in a place near a subject being irradiated with X rays and which imposes no physical burdens.SOLUTION: An X-ray image diagnostic apparatus comprises: an X-ray source for irradiating a subject with X rays an X-ray detection unit disposed opposite the X-ray source via a space in which the subject is positioned, and for detecting the transmission X rays which penetrates though the subject and converting the detected transmission X rays into electrical signals an image processing unit for generating an X-ray image using the transmission X rays detected by the X-ray detection unit and an outer container formed with a shielding material included therein for enclosing the X-ray source, X-ray detection unit, and spaces.COPYRIGHT: (C)2015,JPO&INPIT【課題】 X線照射中の被検体の近傍にいても無効被曝をする虞が無く、さらに身体的な負担を強いることがないX線画像診断装置を提供する。【解決手段】 被検体にX線を照射するX線源と、被検体を配置するための空間を介してX線源と対向配置され、被検体を透過した透過X線を検出して電気信号に変換するX線検出器と、X線検出部により検出された透過X線を用いてX線画像を生成する画像処理部と、X線源、X線検出部、及び空間を囲いX線遮蔽材を有して構成される外容器と、を備えること、を特徴とする。【選択図】 図1
