PURPOSE: An X-ray grid and a manufacturing method thereof are provided to obtain a clear image by reducing amount of X-rays arrived to a film through a subject and an X-ray grid and enhance penetration ration of radiation. CONSTITUTION: An X-ray grid(10) is composed of a plurality of transmission holes(11a) transmitting X-rays, and a plurality of sheets(11) having an absorption part(11b) absorbing the X-rays. The plurality of transmission holes transmits the X-rays which is not scattered among the X-rays passing through a subject. The absorption part forms a clear image in an X-ray film by absorbing the X-rays which is scattered among the X-rays passing through the subject. The plurality of sheets is formed into a mesh shape or a beehive shape. The sheet of the mesh shape obtains structural stability and efficiently eliminates the scattered X-rays from all directions. |
