Abstract
The angle of each collimator plate with respect to an X ray focal point is determined by fitting the collimator plate in grooves formed in upper and lower supports each having an integral structure. In addition, the warpage of each collimator plate is corrected and its flatness is maintained by fitting the periphery of the collimator plate which is on the X ray detector side in a corresponding groove of an abutment plate provided on the X ray detection surface side of the upper and lower supports. Furthermore, each collimator plate is supported by the corresponding grooves of the upper and lower supports and the corresponding groove of the abutment plate on at least three sides.
