Abstract: It is an object of the invention to provide an X-ray diagnosis apparatus having an X-ray plane detector capable of removing the influence of a scattered X-ray by using a grid and also preventing a Moire image. An X-ray image transmitted through a target object is sensed by a plane detector in units of pixels which are two-dimensionally arranged at a predetermined pitch. A scattered X-ray incident on the plane detector is removed by a scattered ray removing grid having plate-like X-ray shielding members and arranged on an X-ray incident side of the plane detector. The X-ray shielding members are arranged such that an X-ray shielding pattern on the X-ray incident surface of the plane detector has a pitch corresponding to an integer fraction of the arrangement pitch of the pixels. When a steady positional relationship is kept between the pitch of the X-ray detection elements and the period of the fringe pattern of the X-ray which is shielded by the grid, a Moire image can be prevented.
