ABSTRACT:
In order to realize a filter that can make a fine spectrum adjustment in a wide rage and can be miniaturized, and to realize an X-ray imaging apparatus provided with the filter, a filter of the present invention is provided with plural filter plates that can form a layer crossing X-ray and adjusting means that adjusts a combination of filter plates forming the layer by individually moving the plural filter plates so as to come in and out the X-ray passing space. The plural filter plates are formed such that the thickness of each filter plate is successively doubled with the thinnest filter plate defined as a reference. The adjusting means has a pair of moving in/out mechanisms for moving, every its half number, the plural filter plates in and out from both sides of the X-ray passing space.
