METHOD FOR MANUFACTURING LATTICE-SHAPED X-RAY GRID

Document Type and Number:

WIPO Patent Application WO/2020/138673

Kind Code:

A1

Abstract:

The present invention relates to a method for manufacturing a lattice-shaped X-ray grid and, more particularly, to a method for manufacturing a lattice-shaped X-ray grid, the method comprising: forming a plurality of grooves on a substrate made of an X-ray permeable material in each of horizontal and vertical directions by using a sawing machine so as to form lattice-shaped grooves in a checkerboard pattern as a whole; putting the substrate having the lattice-shaped grooves formed thereby into a storage tank filled with an X-ray absorbing material in a liquid state; and evacuating the inside of the storage tank into vacuum to cause the lattice-shaped grooves formed on the substrate made of the X-ray permeable material to be closely filled with the X-ray absorbing material in the liquid state. Therefore, the present invention can further simplify a process of manufacturing the X-ray grid and enable easy manufacturing of a lattice-shaped ultrahigh density grid, which is difficult to be implemented by a conventional laminating method.
