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).
