<p>PURPOSE: An X-ray grid and manufacturing method thereof are provided to improve image quality and to minimize a moire phenomenon by effectively eliminating image noise of an X-ray image. CONSTITUTION: An absorption pattern layer(22) absorbs an X-rays scattered from a subject. An X-rays permeable material is laminated at an upper part of the absorption pattern layer. A penetration layer(24) penetrates the X-rays. The absorption pattern layer and the penetration layer are repetitively laminated. The absorption pattern layer is formed into multiple layers. The interval of the line pattern formed in each layer gradually becomes narrow to an upper body.</p> |
