Large area X-ray imager with vented seam and method of fabrication

摘要

A method for forming a large imaging panel by assembling a plurality of smaller submodules, the method comprising providing an adhesive filler between two abutting edges of a first and a second submodule, and forming a degassing channel in the adhesive filler extending along the length of the abutting edges. The method may further comprise adhering the submodules onto a top surface of a base plate, beveling the abutting edges of the submodules, and forming the degassing channel in the space between the beveled edges and the base plate. The method may produce an X-ray image capture panel comprising a base plate; a plurality of discrete array submodules juxtaposed over the base plate, each adjacent to at least one other submodule to form a two-dimensional mosaic of submodules having seams therebetween, each seam being filled with filler material and a vented channel in the seam adjacent to the top surface of the base plate; and a continuous radiation detecting layer disposed over the plurality of array submodules.
