被検体にＸ線を曝射するＸ線発生系と、前記被検体を透過したＸ線を検出し光電変換して出力するＸ線検出系と、前記Ｘ線発生系と前記Ｘ線検出系を対向位置になるように支持するアーム部と、このアーム部を任意角度で回転自在に支持する支持器と、前記Ｘ線検出系から出力された電気信号を画像として画像モニタに表示するためのガンマ補正係数を計算するガンマ補正係数計算部とを備えたＸ線画像診断装置において、前記ガンマ補正係数計算部は、前記Ｘ線発生系に印加する電圧パラメータと、前記Ｘ線発生系と前記Ｘ線検出系の実効距離パラメータ、前記アーム部と前記支持器とのなす角度パラメータの各パラメータの少なくとも一つとの組み合わせからガンマ補正係数を計算することを特徴とするＸ線画像診断装置。an X-ray imaging diagnostic apparatus comprising an X-ray generation system that irradiates a subject with X-rays; an X-ray detection system that detects the X-rays that have passed through the subject, photoelectrically converts the X-rays, and outputs the detected X-rays; an arm that supports the X-ray generation system and the X-ray detection system so that they are opposed to each other; a support that supports the arm so that the arm can rotate at an arbitrary angle; and a gamma correction coefficient calculation unit that calculates a gamma correction coefficient for displaying an electrical signal output from the X-ray detection system as an image on an image monitor, wherein the gamma correction coefficient calculation unit calculates the gamma correction coefficient from a combination of at least one of the following parameters: a voltage parameter to be applied to the X-ray generation system; an effective distance parameter between the X-ray generation system and the X-ray detection system; and an angle parameter between the arm and the support. 前記ガンマ補正係数計算部は、前記各パラメータと前記Ｘ線検出系のＸ線受光面積の大きさパラメータの少なくとも一つとの組み合わせからガンマ補正係数を計算することを特徴とする請求項１に記載のＸ線画像診断装置。2. The X-ray imaging diagnostic apparatus according to claim 1, wherein the gamma correction coefficient calculation unit calculates a gamma correction coefficient from a combination of each of the parameters and at least one parameter of the size of the X-ray receiving area of the X-ray detection system. 前記Ｘ線検出系は、イメージ・インテンシファイアであることを特徴とする請求項１又は２の１項に記載のＸ線画像診断装置。3. An X-ray diagnostic imaging apparatus according to claim 1, wherein the X-ray detection system is an image intensifier.
