PROBLEM TO BE SOLVED: To provide an X-ray diagnosis apparatus which forms fluoroscopic images of a high resolution while forming fluoroscopic images of a normal resolution without increasing the X-ray exposure amount to a subject.SOLUTION: An X-ray diagnosis apparatus 10 includes an X-ray generating section 12, a displacing mechanism 25, a normal image forming section 31, and a high resolution image forming section 32. In this case, the X-ray generating section 12 radiates X-rays to a subject. The displacing mechanism 25 has a plurality of X-ray detecting elements which are arranged in a row at specified central intervals on a radiation surface facing the X-ray generating section 12, and repeats the changing of the relative position between the radiation surface of a flat-surface detector 24 and the X-ray generating section 12 to an initial position and a plurality of shifting positions which move in a direction being in parallel with the radiation surface from the initial position in order. The normal image forming section 31 forms an image corresponding to each of the positions conforming to a radiation detected by the flat-surface detector 24 at each position of the plurality of shifting positions. The high resolution image forming section 32 forms images having a resolution being higher than those of the plurality of images conforming to the plurality of images corresponding to the respective positions which have been formed by the normal image forming section 31.COPYRIGHT: (C)2013,JPO&INPIT【課題】被検体に対するX線被ばく量を増大させることなく、通常解像度のX線透視画像を生成しつつ高解像度なX線透視画像を生成するX線診断装置を提供する。【解決手段】X線診断装置10は、被検体へX線を照射するX線発生部12と、X線発生部12に対向する照射面に所定の中心間隔で行列に配置された複数のX線検出素子を有し、平面検出器24の照射面とX線発生部12との相対的な位置を、初期位置と、初期位置から照射面に平行な方向に移動した複数のシフト位置を順次変更することを繰り返す変位機構25と、複数のシフト位置の各位置で平面検出器24に検出された放射線にもとづいて、各位置のそれぞれに対応する画像を生成する通常画像生成部31と、通常画像生成部31により生成された各位置のそれぞれに対応する複数の画像にもとづいて、これらの複数の画像よりも高い解像度を有する画像を生成する高解像生成部32と、を備える。【選択図】図1
