Abstract
A collimator includes a collimator body formed by 3D printing technology and one or more side plates formed by non-3D printing technology. The collimator body includes first through holes, body side walls, and openings located on at least one side of the collimator body. The first through holes and the openings are enclosed by respective body side walls, extend through the collimator body, and are arranged in an array. The one or more side plates have a thickness smaller than a thickness of the body side walls, and are connected with the at least one side of the collimator body to constitute second through holes together with the openings. Each through hole has a square-frustum-like shape with extension lines intersecting at a focus of an emission source of X rays, such that the X-rays pass through the through hole.
