PROBLEM TO BE SOLVED: To ensure that scattered X-ray and injurious stripe patterns and artifacts which occur on an X-ray image by an absorbing board even with dynamic X-ray photography are in particular effectively suppressed with as low production cost as possible.SOLUTION: A grid for removing scattered X-ray (1) which is provided for a X-ray detector (11) having an active pixel matrix, comprises an absorbing board (4) arranged approximately parallel to a radiation direction of an X-ray (17) and reduces the scattered X-ray in X-ray equipment (10). In the grid for removing scattered X-ray (1), the absorbing board (4) can shuttle vertically to the radiation direction of the X-ray (17) at a minimum frequency of 10 Hz and at a maximum frequency in a step of 2-pixel size of the X-ray detector (11) which can be installed on the grid for removing scattered X-ray (1).COPYRIGHT: (C)2007,JPO&INPIT【課題】できるだけ少ない製造費用で、散乱X線と、動的X線撮像法においてもX線画像上に吸収板によって生じる障害的な縞パターンおよびアーチファクトとを、特別に効果的な抑制することを保証する。【解決手段】アクティブピクセルマトリックスを有するX線検出器(11)のための散乱X線除去用グリッド(1)であって、X線(17)の放射方向に対してほぼ平行に配列された吸収板(4)を備え、X線装置(10)における散乱X線を減少させる散乱X線除去用グリッド(1)において、吸収板(4)が、10Hzの周波数最小値および散乱X線除去用グリッド(1)に付設可能なX線検出器(11)の2ピクセルサイズの行程最大値にて、X線(17)の放射方向に対して垂直に往復移動可能である。【選択図】図1
